9 2 INTRODUCTION ORTEC Detective series, Detective EX/DX series handheld and Detective -200 high-purity germanium (HPGe) radioisotope identifiers (RIIDs) are widely used around the world by law enforcement, security agencies, military and customs agents in the fight against illicit nuclear materials trafficking. ORTEC Detective identifiers and the Detective -SPM spectroscopic portal monitor combine the superior resolution of HPGe detectors with the speed and accuracy attributable to ORTEC advanced algorithms to be the most accurate and sensitive means for search and identification of radioactive material. Incorporation of Detective -200 rugged identifiers and comprehensive GPS location mapping capability with powerful software makes the Detective-Remote Search System effective for mobile search and identification on land, sea, or air. To summarize Detective-Remote provides real-time radionuclide detection and identification for Homeland Security, Customs and Emergency Response in mobile or stationary monitoring applications. Detective-Remote System Applications Mobile Surveys Detective-Remote analyzes for the presence of radionuclides as it is transported through areas of interest. Stationary Monitoring Detective-Remote is used for static monitoring at chokepoints for pedestrians, autos, trucks or boats. Detective-Remote System Features Available system configurations and mounting options are flexible and subject to change without notice. See our website or contact your ORTEC Representative for current product information. When purchased with Detective instruments, Detective-Remote is shipped as a turnkey solution, factory-configured and ready to use after the Detective units are powered and cooled. Detective-Remote performs searches in energy, time, and position for the highest probability of detection of point-source or distributed radionuclides. Fixed or flexible arrays of Detective subsystems 2. Each Detective unit is comprised of an HPGe detector, Stirling cycle cooler, an integrated computer and application interface. Integrate your existing ORTEC portable identifier or IDM into a Detective-Remote system. Consult Appendix B.1 to determine the compatibility of your identifier with the system. Contact your ORTEC Representative or our Technical Services Group to obtain the necessary software. 2 The Detective-Remote system is designed for use with ORTEC ultra-sensitive Detective -200 identifiers. Detective - Remote may be integrated with a variety of other Detective series instruments into a system. In this manual, the term detector subsystem is used when emphasizing the hardware or software components of the standalone, intelligent identifiers. 9

10 Data streaming from detector groups in 1-second, loss free measurements, are analyzed as a series of rolling-average data integration windows. These data integration windows, hereafter referred to as data integrators, are set for multiple strategic time periods for data analysis. Detective- Remote combines the data from multiple detectors for the most sensitive, accurate detection and identification capability. All survey and analysis data, including spectra, gross gamma count rates, (and optionally neutron count rates 3 ) GPS locations, and radionuclide identifications, are captured in a Microsoft SQL Server database. A new database is created and saved for each survey. Integral GPS and mapping software provide a complete history of the survey route and source locations. Detective-Remote is supplied with the OpenStreetMap (OSM) open-source world map software 4. Detective-Remote is compatible with other map systems including ESRI Shape File, Oracle JNDI, PostGIS, H2, GeoTIFF, ArcGrid, Gtopo30, ImageMosaic, WorldImage, WMS, Bing Maps, and Google Maps. -based reach-back simplifies communicating field data to anyone with internet access. IEEE wireless or wired USB communication may be used to transfer data from detectors to the host computer(s). Both wireless and wired connection types may be used simultaneously. Easy-to-use software interface with extensive rollover tool tips describing the controls and tools. Flexible user interface lets you customize the data views available in idle, search, stand-in, background, and review modes. Optionally generate ORTEC.CHN-format survey and background spectra from the Spectrum or Reach-back tab for any system detector. These spectrum files can be viewed with the accompanying MAESTRO MCA Emulation Software or its WINPLOTS spectrum plotting program. The CHN spectrum output may also be read with Peak Easy. An experienced spectroscopist can use the LCX (Low-Confidence Expert) identification mode (see Section 4.3.3). 3 Helium-3 neutron detectors currently have restricted availability. Please contact your ORTEC Sales Representative to determine their availability for your application. Alternative Li6 Neutron detector panels are available for inclusion into the Detective Remote system. 4 Open source map contents subject to change without notice. 10

11 One- and Two-Computer Configurations In the standard configuration, all computer software components are installed and run on a single computer. In the optional two-computer configuration, the User Interface program runs on computer #1, (the user interface computer); and the Analysis, Database Maintenance, and GPS Server programs run on computer #2 (the analysis computer). Both computers have the complete Detective-Remote software suite, but Microsoft SQL Server 2012 and map software are installed only on computer #2. During initial installation, computer #2 (the analysis computer) is configured to receive the stream of survey data provided by computer #1 (the user interface computer) through computer #2 s ad hoc wireless network. This setup is the same whether detectors are connected to computer #1 via IEEE wireless or USB connections. An alternative is to connect computers 1 and 2 via wired Ethernet. Setting up additional User Accounts The Detective-Remote computer(s) are factory-configured with a Detective-Remote user account. You may create additional accounts tailored for different detector and group configurations. Contact your ORTEC representative or ORTEC Technical Services Group for more information. Low Maintenance, 24/7 Readiness ORTEC Detective series instruments are essentially maintenance- free as they have no user-serviceable components and are designed for years of continuous duty. The instruments do not need to be returned to factory for calibration as this function is readily performed by the user or in newer models it is done automatically when the background is performed. Between uses, these units should be connected to an external power source with the coolers running to keep the detector at operating temperature. Computers and network hardware can be powered off and on as needed. 2.1 Hardware and Software Components 5 One to eight Detective -200s or compatible detector subsystems, factory-configured with all supporting Detective-Remote software applications. One or two 64-bit Microsoft Windows 7 computer (s) running the Detective-Remote application and ancillary software. Garmin GPS 18x USB global positioning device or equivalent. A valid TCP/IP network that connects all of the computers and detectors. The network can be wired; or IEEE wireless using either ad hoc (peer-to-peer) or infrastructure (point-source) mode. The computer(s) and detector(s) can be connected via USB cable, or a combination of wired - USB and wireless - TCP IP LAN connections may be used. 5 Visit our website, or contact your ORTEC Representative for the most up-to-date product information and system specifications. 11

12 2.2 General Receiving and Inspection Unpacking instructions are posted on the outside of all shipping containers Shipping Damage If a shipping carton arrives with externally visible damage, do not unpack it. Notify the carrier and make arrangements to file a damage claim. In all cases of shipping damage, it is the customer s responsibility to file a damage claim. If, during unpacking, you find concealed damage, notify the carrier and file a claim. Packing materials, way- bills and other such documentation should be preserved to establish claims. Contact our Global Service Center, (865) , for further instructions. Outside the U.S., contact your local ORTEC Representative Unpacking Instructions Open all shipping containers and immediately inspect the contents for physical damage. If any of the contents appear to be damaged as a result of shipping, see Section How This Manual Is Organized This manual generally assumes you have the turnkey system comprising one or two computers and one to eight Detective 200s (or other compatible ORTEC Detective products), with the connection method (wireless or wired, USB) pre-configured at the factory. However, Appendix B tells how to incorporate additional detectors into your system. Chapter 3 System setup quick-reference. Chapter 4 Overview of key concepts and system operating pre-cautions.

13 3 PREPARING FOR FIELD USE This chapter highlights the steps involved in Detective-Remote system setup and includes references where to find additional detail information in subsequent chapters and appendices. These instructions assume you will initially be setting up the system indoors to test component connectivity, configure the user interface, and seed (pre-cache) the map for your local search area. However, all the setup steps may be performed in the search vehicle, one exception being that the analysis computer must temporarily be connected to the internet for map seeding. Most users will have a one-computer system, and can ignore dual system setup reference to analysis computer and user interface computer, which apply only to the dual computer setup. 3.1 Detector Cool down TIME: 8 24 hr Collect the hardware manuals for all portable identifiers (with integrated computer) and interchangeable detector modules, (no computer) hereafter referred to as IDM s. For the IDM, you must know how to apply power, and turn the unit on to begin cooling the detector. For the identifiers, you must know how to connect them to external power, start the ORTEC Launcher application then start the unit s identifier application to turn on the cooler, monitor the hardware status screen during cool down, and exit to the Launcher or to Windows Mobile. It will also be good to know the anticipated time required to cool and charge the internal and auxiliary battery for each type of instrument. While the detectors are cooling, continue with system preparation and ignore any system alarms in the Detective-Remote User Interface program. 3.2 Start Computer(s) and Prepare Mapping TIME: 1 6 hr For wireless systems, start the analysis computer first and log in on the Detective-Remote user account. The factory default password is ORTEC (all uppercase, no parenthesis). Follow the instructions in Section 5.2 and Appendix B for instructions on how to connect to the wireless LAN. In 2 computer systems next, start the user interface computer and log in using the same credentials. 3.3 The Default Open Street Map When using the default OpenStreetMap (OSM) map, it is already installed on the analysis computer and pre- configured. OSM should be ready for you to pre-cache (seed) the map tiles for your planned search area that is, download them from the ORTEC mapping service for offline (field) use 6. After any map download for a particular area, the information is retained in the database for future use without seeding. See Section 9.3 for seeding instructions. 6 Detective-Remote can also access the map server in real time (where signal strength permits) if you have a cellular modem or are tethered to a mobile phone. However, the turnkey Detective-Remote system does not have real-time access, so this manual discusses pre-caching. Consult your IT department or our Technical Services Group for more information on real-time access. 13

14 3.3.1 Installing Your Own Map System TIME: hr If using your own map, you must first copy it to the analysis computer (Section 9.2). It is then treated as a layer on the Map tab, and can be turned on and off, and optionally used in combination with the OSM map and other map layers. NOTE: Alternate map layers are stored in their entirety on the analysis computer. Therefore, if you intend to use only your added map layers, rather than the default OSM, there is no need to connect to the internet and download a cache of map tiles from the map server before going into the field. However, if you plan to use the OSM as well as your own map(s), you must pre-cache the OSM tiles. 3.4 Integrate Additional Detector Modules into the System TIME: hr /detector If you will be adding other identifiers or interchangeable modules to the system, follow the procedure in Appendix B for each new wired or wireless detector connection 7. The final step of this procedure will be to run the Setup and Options program, as discussed in Section 3.5 below. Note: You can temporarily remove your standalone identifier (e.g., Detective or trans-spec series units) from the Detective-Remote system to take a closer look at an object of interest. For additional information see Appendix B. 3.5 Connect the Detectors to the Computer TIME: hr Wired Systems On startup, the identifier touchscreens should show the Mobile MCB Server set to the USB Control option (see Figure 7). Detective -100 and trans-spec-100 series units must be wired from the rear-panel CONTROL port to the analysis computer. All other identifiers have only one USB port. Cable all interchange- able detector modules from the USB connector to the analysis computer. If this is a turnkey system and you are not adding more detector modules to it, skip to Section 3.6. If you have added more detector modules to your system (Section 3.3), you are now ready to start the Setup and Options program (Section 3.5) Wireless Systems (Identifiers Only) On startup, the touchscreen should show the Mobile MCB Server set to the Wireless/ActiveSync option. The identifiers should connect to the analysis computer s ad hoc network within a few minutes. If this is a turnkey system and you are not adding more detector modules to it, skip to Section 3.6. If you add additional detector modules to your system follow instructions in (Section 3.3 and Appendix B) to incorporate them into the system. You are now ready to start the Detective-Remote Setup and Options program (Section 3.5). 7 After you integrate an additional identifier into Detective-Remote, you can remove it for use in its standalone portable identifier mode, then reconnect it. In standalone mode, you can perform any function in the various identifier/ spectroscopy applications, including running backgrounds, without any effect on Detective-Remote. Likewise, none of the Detective-Remote settings affect standalone identifier operation. 14

15 3.6 Run the Setup and Options Program TIME: hr ORTEC Detective -Remote (780490) There are limited circumstances which require the user to access and make changes through the Setup and Options program. Those circumstances are as follow: On first startup of a new system to modify data integration times, detector group assignments, or reachback settings. To enable a new detector in the system and assign it to one or more detector groups. If you add a new detector module to an existing system, you need visit the Startup and Detector Groups tabs in the Setup and Options program. After installing an upgrade of Detective-Remote software. To acknowledge multiple outstanding alarms from the last work session (for instance, if you trigger a series of hardware alarms by using the computer[s] without the detectors, e.g., for survey review). NOTE: There are three general interfaces within Detective-Remote 1) System Startup, which launches /marshals various programs to incorporate their functionality, including GPS, data acquisition, database management etc. 2) Detective-Remote User Interface, This interface allows the operator will run the program. 3) Set up and Options. This is the location where changes in the setup control how Detective- Remote User Interface operates. Anytime Set up and Options is accessed the two other interfaces must be closed (shutdown) or changes made will not take effect. The Detective-Remote System Startup program automatically starts each time the computer is booted, therefore, the first step is to close it by hovering the cursor above the DR icon ( ) in the system tray. When the popup appears, click the ( ) in the upper-right corner to close. Shutdown takes about 5 seconds after this is done. If the Detective-Remote User Interface program is open, it will also need to be closed before making changes to Detective-Remote Setup Options program. 15

16 Start the Detective-Remote Setup and Options program. Before the first use of a new system, check the settings tabs as follows. Startup Verify that all of the detectors in your system are listed in the Detectors section, and that the checkbox beside them is marked. Otherwise, they will not be used for data collection. Detector Groups On factory-configured Detective-Remote systems, an ALL detector group (containing all the system detectors) is defined at the factory. To create one or more new detector groups, or to add a new detector to existing groups, see Section 3.4, and Appendix B. If any of the detectors you plan to use are missing from the list or are displayed in red, go to Section 5.3.3, to troubleshoot. Display To change the default settings in DR setup, see Section For additional information on setting up the display screen in the User Interface, refer to Chapter 5. Acquisition The default background count time is 1200 seconds. Your CONOPS will determine the length of your minimum background count period; we recommend 1500 seconds as a minimum. The suppress background ID alarms option is enabled by default to minimize nuisance alarms. To change the default settings, see Section For more information about performing a background measurement refer to section 7.2. Alarms The optional speed-limit alarm default setting is 8 mph (13 kph). To change the alarm speed, see Section Integration Times ORTEC strongly recommends that initial use of the default, generalpurpose 8- and 30-second integrators. Be sure to read the system concept and integration time discussions in Chapter 4. Reach-back Optionally enter a reachback recipient s information, refer to Section for details. Status Graphics Controls the appearance of the User Interface program s Status tab. To reposition the detector group icons and/or change the vehicle.jpg, see Section Manage Surveys - Survey database file exports, imports and deletions are performed using the Manage Surveys tab, see Appendix C. You are now ready to close Setup and Options and start the System Startup program. If you have not entered an Recipient in reach back settings, a pop-up reminder will be displayed when you exit the Setup and Options program. Click No to ignore the message and close Setup and Options. 16

17 3.7 Start the System Startup Program TIME: 0.1 hr ORTEC Detective -Remote (780490) On the analysis computer, start the Detective-Remote System Startup program, wait for it to initialize and display the DR icon ( ) in the system tray. Click the icon, and ensure all items on the popup window have a green check mark. If any of the System Startup components have a problem, the DR icon will be flagged with a yellow caution indicator. If any of the detectors show a yellow or red icon, go to Section 5.4 for troubleshooting instructions. If the icon for either of the top two entries is yellow or red, contact our Technical Services Group. If the GPS antenna is disconnected from the analysis computer, the DR icon will be flagged with a yellow caution, the GPS Server entry on the DR popup will display a yellow indicator, and the Franson GpsGate tray icon will be red ( ). When the system is mounted in the survey vehicle and the GPS antenna is connected (Section 5.5) and receiving satellite signal, the Franson Gps- Gate icon and GPS Server indicator will turn green. IMPORTANT: Leave the System Startup program running. It must run together with the User Interface program in order to analyze detector data streams for IDs and alarms, capture comments, record GPS coordinates for each measurement (where GPS signal can be detected), and save survey and background data to the survey database. If Detective-Remote System Startup is accidentally closed during a survey, the User Interface will continue in Survey Mode, but no data analysis will take place and the search will be invalid. If it is inadvertently closed follow these steps, 1) End the search, 2) restart System Startup, 3) restart the survey. 17

18 3.8 Start the User Interface Program TIME: 1 hr Start the User Interface program on the User Interface computer. The User Interface application has five modes (Idle, Background, Search, Stand-in, and Review); and 10 data display tabs (Detectors, Measurements, Events, Alarms, Detector Health, Strip Charts, Status, Map, Spectrum, and Reachback). Not all data display tabs are available in all modes, there is a reference table of tabs available from each mode in the overview of major screen features in Section 6.1. The Detective-Remote User Interface into the mode last used. Whenever possible return to Idle mode before closing the program. A new system opens the first time in Idle mode, with the Detectors tab displayed on the left side and the Detector Health and Events tabs on the right. The Detectors tab should show a detector status indicator for each detector in the system. When the system is ready for radiation surveying, all status indicators will have a white background and the lower-left corner will indicate Idle mode, as shown in Figure 37. See also Figure 38, which shows examples of detector operational and error states. If a status indicator is amber and indicates a communication error, go to Section 6, and troubleshoot. If an indicator is amber and indicates a warm detector, allow the system to continue cooling If an indicator is amber and indicates an expired background, gain stabilizer, or FWHM error, ignore for now; these will be resolved when you perform the Background measurement. Each mode (Idle, Search, Stand-In, Background and Review) has its own default selection and layout of tabs. Add as many as you wish from the tab selection list (see Figure 28), and arrange them as needed (Section 6.3). After all detector temperature errors are resolved, click the Background button. You may wish to add the Detectors tab to the Background mode and monitor the status messages. To do this, click the upper-right Show... button and click Detectors Tab. At the end of the Background measurement, the system will automatically return to Idle mode. On the Detectors tab, ensure all expired background, gain stabilizer, and FWHM errors are no longer displayed, all backgrounds are white, and all are in Idle mode. If any detectors still show errors, contact your ORTEC Representative or Technical Services Group. *** You are now ready to transfer the system to the search vehicle *** 3.9 Mount the System in the Search Vehicle TIME: Variable Two options for placing system in the vehicle: One option is to leave the hardware and software running in its current state and migrate it to the vehicle. Second option is to lose Detective-Remote Startup by hovering over the DR Icon in the tray and when the status box appears click the X in the upper right corner to close. Shutdown the computer. 18

19 In wired systems, disconnect the detectors from the analysis computer, install the units, in the vehicle and reconnect. Mount the laptop in the vehicle and attach the GPS antennae. Start the computer and launch the Detective-Remote System Startup. Most often DR will reestablish network communication within about 5 minutes. In wireless systems install the units in the vehicle, mount the laptop, install the GPS, then start the computer. Launch Detective-Remote System Startup. Most often DR will reestablish network communication within about 5 minutes. However, if communication with all identifiers is lost, follow the troubleshooting instructions in Section 10. Connect the GPS antenna to the analysis computer (if it is not connected, or is connected to the user interface computer, no map data will be collected during surveys). For best results mount the antenna on the outside of the vehicle although for temporary installations mounting in the dashboard of the vehicle may work adequately. When connected the Franson GpsGate tray icon will change from red to green ( ) and the DR icon will no longer display the yellow caution indicator. (If the Franson GpsGate icon remains red, see the troubleshooting steps in Section 10.3.) On the User Interface computer, click the Detectors tab and confirm all detector status indicators are white and in Idle status. Acknowledge any alarms. You are now ready to perform an initial search, preferably with a test source, to familiarize yourself with system behavior and the appearance of alarms on the various tabs. Choose the tabs you wish to display in the various modes. The Detectors, Events, and Map tabs are displayed by default for both Search and Stand-In surveys. You may also wish to display the Alarms, Charts, Status, and Measurements tabs Survey Site Background Measurement TIME: 0.75 hr The first steps when you arrive at the survey location will be to obtain a GPS fix then perform a Background measurement (See Chapter 7). *** Your system is now ready for radiation monitoring. See Chapter 8 *** 19

20 4 OVERVIEW AND KEY CONCEPTS This chapter discusses the key concepts to data collection and analysis in Detective-Remote. Additionally it provides an introduction to the system s software components and operation modes; and discusses alarms and alarm, data management, and system operating cautions and limitations. 4.1 Problem and Solution Wide-area radiation searches pose a substantial four-dimensional challenge. Depending on the situation and survey site, objects of potential interest may be in orderly arrays at known distances in a well-defined area (e.g., rail cars, a harbor of closely moored ships, containers stacked in a freight yard), or sparsely and randomly scattered across broad expanses of soil or water, or secreted in one vehicle somewhere among thousands at a major city s holiday celebration. How do you sweep miles of territory for one or multiple threat radionuclides at one or multiple distances? How do you isolate a threat identification apart from all of the innocent radiation sources surrounding us? How do you collect and analyze the survey data to solve this four-dimensional problem? The solution to these challenges is the Detective-Remote Mobile Search System: Comprised of one to eight of our Detective -200 high-resolution HPGe identifiers mounted for mobile survey, and coupled with GPS and a mapping capability. Detective-Remote can utilize almost any map system, including but not limited to OpenStreetMap (the system default), or your ESRI Shape File, Oracle JNDI, PostGIS, H2, GeoTIFF, ArcGrid, Gtopo30, ImageMosaic, WorldImage, WMS, Bing Maps, or Google Maps. You deploy the Detective instruments in pre-defined groups (say, one group of eight forward-facing; or two groups of four, left-facing and right-facing). Each detector continually streams spectral data, which the software analyzes approximately once per second. The net result of each once-per-second evaluation of all integration times for all groups is called a measurement. Each measurement in a survey is numbered and tracked on the User Interface program s Measurement tab (see the left side of Figure 39). The stream of measurements for all detectors in a group are combined and simultaneously analyzed as a rolling series of shorter-duration windows and longer-duration windows. You select the duration of the rolling analytical windows, which we will call data integrators. The selection of data integrator windows will be based upon your knowledge of: 1) The speed at which the survey will be conducted. 2) The expected distance(s) between source(s) and the detector group. 3) The detector group s effective field of view (FOV). The effective FOV is dependent upon the horizontal and vertical spacing of the detectors. 20

21 These factors allow you to estimate the number of seconds that sources will be in the detector group s effective FOV at varying distances. As a rule of thumb, short-duration analyses will tend to identify sources closer to the detectors while longer-duration analyses will tend to find the source at a greater distance. Figure 1 depicts a detector s data stream, processed as 1-second measurements that are subsequently analyzed in 8-second rolling windows for radionuclide IDs. Figure 1 Rolling-Window Analysis of Detector Data Stream at 1sec intervals. Figure 2 illustrates the effects of the vehicle speed, source-to-detector distance, and detector group FOV for a survey conducted at 5 mph (~7 ft/s) and a detector group FOV of 120 degrees. Detective-Remote is factory-configured to use 8-second and 30-second data integrators, a solid, general purpose pair of integrators. However, the Setup and Options program lets you choose the number and duration of data integrators for your detection scenario (see Section 4.1.1). 21

22 IMPORTANT Changing integration times can dramatically reduce the system s ability to locate radionuclides. Figure 2 Speed, Source Distance(s), and Detector Group FOV Interactions in Mobile Searches. Integrator intervals should reflect the amount of time the source is in each detector s field of view (FOV) and in the entire array s FOV. Thus, a vertical stack of detectors might use shorter integration times than a horizontal array. Array FOV should be determined on the basis of your system s geometry relative to the anticipated location of the radioactive source and multiple integrators should be used when you anticipate a wide range of source-to- detector distances. Note: The number of detector groups multiplied by the number of data integrators determines the number of passes the analysis engine must make each second. More detectors and multiple data integration times increase the amount of computer power and time to process data. To avoid throughput issues, we strongly recommend not more than four data integrator times. The lowest useful integrator interval is 2 seconds. The 2 second integrator is likely only practical for a controlled-speed portal monitor configuration with a vertical array of detectors. Modeling the expected sources, distances, vehicle speed, shielding, collimation, and other factors will help determine the appropriate set of data integrators for a fixed number and type of detectors to provide the best results for your application. Contact your ORTEC Representative or ORTEC Technical Services Group for more information Changing Data Integrators Can Improve Source Resolution What happens when two sources of the same kind are so closely spaced that both are detected within one data integration period? In the upper part of Figure 3, an 8-second data integrator is in use, and the two sources generate a single ID event in rolling windows

23 The lower part of the figure shows that a 4-second data integrator detects the two sources separately, in rolling windows and NOTE: If the second ID occurs less than 4 seconds after the end of the first ID, Detective-Remote treats it as a continuation of the first ID. Stated another way; in this instance while using an 8- second integration window if a second source passes into the FOV within 8 seconds, Detective-Remote treats the second source as a continuation of the first ID. Changing the integration window to 4 seconds, and keeping source passing through 5-8 seconds after the first source passes, Detective-Remote will see both sources. This diagram is intended to illustrate the kind of effect that changing a data integrator may have on source detection. In the field, the effects of changing data integrators may not be this predictable and must be explored with scenario modeling! 23

24 Figure 3 Changing Data Integration Time May Help Resolve Closely Spaced Sources. 24

25 4.1.2 Rolling-Window Analysis vs. Data Display in Detective-Remote ORTEC Detective -Remote (780490) For simplicity, let us say Detective-Remote typically identifies a radiation source 0.75 second to 1.0 second after the source enters a detector group s FOV 8. This means that as a detector group moves into view of a source, the source ID will be posted in the last 1 second of the oldest live rolling window (for an 8-second integrator that would be the window that started 7 seconds ago), and that ID will persist for one integration period (8 seconds) after the source exits the detector group s FOV. This is illustrated in Figure 4, which shows approximately 22 seconds of detector data. Data stream measurements 9 through 31 are shown here. They are analyzed in fifteen 8-second rolling windows. During this time, the detector sees a threat source for approximately 2 seconds, beginning at the end of rolling window19. Identification occurs in rolling window 20 and ends shortly after the start of rolling window 28. Rolling window 29 does not see the source. Thus a 2-second radiation exposure affects nine 8-second rolling windows and nine measurements. Note how the various aspects of this ID event are reflected in the User Interface program s data displays. Measurements tab When you start a search, the Measurements tab begins tracking the1-second data stream measurements. Measurements that do not generate IDs have a white background. You can see that when the threat ID Neutrons on Fe is posted in rolling window, measurement 20 (see Figure 4), the display background turns red and the threat ID is posted. The red background and threat ID name persist through Measurement 28. Measurement 29 (not shown) will have a white back- ground. Events tab The Events tab registers an ID event for the threat Neutrons on Fe. Note the red background; the event duration of 2.0 seconds; and the event date and time, which match the date and time of Measurement 20. Charts tab The Signal and Threat Index data scroll from right to left, so the oldest data are on the left. The two charts show 22 data stream measurements, from measurements 9 through 31; with the identification of a threat beginning in measurement 20 and ending in measurement 28. The low amplitude of the Signal Index indicates that the radiation source was relatively weak; however, the very high Threat Index value indicates the analysis engine identified the threat at very high confidence. Both charts registered the 2-second radiation exposure across nine measurements, after which both indexes dropped to zero. Alarms tab Not shown here, the entries on this tab drop off after (1) they are acknowledged and (2) the data integrators no longer see the ID event. In this case, the alarm entry was displayed for nine measurements. 8 The brief period from the detector s first view of a source until the analysis engine identifies it and posts an ID event is affected by numerous factors, including source strength, vehicle speed, data integrator times, source to detector distance, the number and type of detectors in a group, their horizontal and vertical spacing, hardware and software timing and throughput rates and counting statistics. 25

26 Figure 4 ID Event and Data Display in Detective-Remote. 26

27 4.1.3 Data Display on the Map Tab An ID event posts simultaneously on all tabs as soon as the confidence level reaches a threshold value specific for the detected radionuclide (i.e., different radionuclides post ID events at different confidence levels; this is internal to the analysis engine). Depending on source strength and location, this alarm may display only a fraction of a second after the source enters the detector s FOV. Then, because of the wide FOV, the source may remain in the detector s view for several seconds after the ID event is posted, during which time the confidence level for the ID will likely increase. As a result, the point at which the analysis engine calculates the ID with highest confidence may occur after you have passed the source (this effect will be more exaggerated with longer data integration times). The Map tab tracks this change in confidence level. It posts a triangular ID Event icon ( ) on the map at the same time the other tabs respond. Then, as long as the confidence level for the ID increases with each subsequent measurement. The Event icon shifts in the direction of travel until the measurement with the highest confidence level is calculated. The Event icon is then fixed at the site of that measurement 9. Thus, a time period of a few seconds may separate the posting of the alarm and the final position of the Event icon on the Map tab. As a consequence, the Event icon s position on the map may not mark the actual source location. Keep this in mind during surveys and data review, and use all of the User Interface data visualizations together to derive the best information about source location. Example: At a vehicle speed of 8 mph (12 ft/s), if the User Interface posts an ID event at the measurement Max cps in Figure 5, then another 4 5 measurements elapse before the highest confidence level is calculated for the ID (Max Q), the final position of the Event icon may be feet beyond the actual source location. Figure 5 Rolling-Window Analysis of Detector Data Stream. 9 To visualize this, observe the Measurements and Map tabs for a survey that includes an innocent or threat ID event. On the Measurements tab, click each measurement for the event, and note how the confidence level (Q value) changes from one to the next. Locate the entry with the highest Q and observe that it correlates with the position of the ID Event icon on the Map tab. 27

28 Note: In the previous figure, the user has changed the default blue breadcrumb color and assigned a color gradient based on increasing count rate. The color of the count-rate breadcrumbs peaks in intensity at Max cps, a few measurements before the red ID Event icon and detection zone reach their final position at Max Q. This is a good indication that the source is located west or northwest of the event icon. The Signal Index on the Charts tab also provides information about source location. As you approach a source, the Signal Index almost always increases before an ID event is posted. If the source is a threat nuclide, the Threat Index begins to increase as well. Taken together with the timing of the alarm (and an optional color gradient for the breadcrumbs), they should be helpful in pinpointing the source. 4.2 Software Overview Software Components Detective-Remote has four software components. Setup and Options (Section 5) System Startup (Section 5) This program identifies and governs the detectors to be used and their optional distribution into detector groups, data analysis parameters, background count time, and how alarms will be presented to users. Always run Setup and Options with the other two components closed, also close Setup and Options before starting the other two components. Must be running to analyze detector data streams for IDs and alarms, capture comments, record GPS coordinates for each measurement (where GPS signal can be detected), and save survey and background data to the survey database. User Interface (Chapter 6) Controls only the display of the user interface screens and Review mode data. Note that you can review existing surveys with just the User Inter- face program. However, to collect data and monitor the detectors, the Detective-Remote System Startup program must also be running. Sensor Portal Mapping Platform (Section and Chapter 9) Provides real-time, map-based monitoring and review of historic map data. GeoServer open-source map tile server supplies worldwide streetlevel map display, can optionally serve maps from almost any source, and mediates caching of map data on the Detective-Remote analysis computer for use in the field/offline. 28

29 4.2.2 Operation Modes There are four operating modes: Mode Idle (Figure 26) Survey (Section 8) Description The User Interface home screen. Gamma count-rate, gamma dose- rate, and (where applicable) neutron count-rate meters are active and displayed, but no data are saved. Search Manually timed survey intended primarily for mobile searches. The system events, measurements, IDs, ID durations, alarms, strip charts, and measurement-to-measurement detector status for a survey are saved in a database, one database per survey. Stand-in Designed for stationary monitoring, performed to a user- defined counting preset in the Setup and Options program. All survey data are saved in a database, one database per survey. Background (Section 7) Review (Section 8.2) Performed to a user-defined counting preset (1200 seconds minimum) in the Setup and Options program. The frequency and duration of back- ground measurements will depend on your site operating procedures. Select any survey and review the map and all events, measurements, IDs, alarms, strip charts, and spectra. 4.3 How Survey Data Are Collected and Analyzed As discussed in Section 4.1, each detector in the system transmits a continuous stream of spectrum data, which the software measures approximately once per second. The data streams for all detectors in each group are then combined for analysis. The combined group data stream is analyzed differently in the two Survey modes Search Mode vs. Stand-In Mode Search Mode In the mobile Search mode, the combined data stream from each group is simultaneously analyzed with (by default) rolling 8-second and 30-second integrations. This focuses the analysis on different distances normal to the search system. The Setup and Options program lets you use a different number of integrators and different durations (see Section 8) Stand In Mode Stationary Stand-In counts are designed to maximize the system s ability to detect radiation. Instead of the rolling-window analysis, each detector group s combined data stream is analyzed cumulatively each second for IDs and alarms. Thus, the survey contains analyses for the data periods from (t = 0 to t = 1 s), from (t = 0 to t = 2 s), then (t = 0 to t = 3 s), and so on to the end of the measurement period. 29

30 4.3.2 Background Peak Filtering In gamma spectroscopy, the concepts of background measurement and background subtraction may have different meanings for different types of detectors. For high-purity germanium (HPGe) spectra, peak-by-peak background subtraction is used. Detective-Remote uses HPGe detectors, but takes a slightly different approach to the background measurement. The Background function determines, peak-by-peak, the net background count rate for each of the 72 peaks listed in A.2. These peak energies are associated with innocent background NORM (naturally occurring radioactive material) radionuclides. The peak-specific, net background count rate is used as a filter with each survey spectrum before it is analyzed for alarms. The filtering of these 72 peaks minimizes the frequency of alarms for naturally occurring radioisotopes to prevent them from becoming a nuisance when trying to focus on real threats. This filter can be turned off as discussed in Section While performing a background with the instruments, the Background routine also aligns the 1460 kev peak of K-40 in the factory-specified energy channel and pinpoints the gain stabilizer to the area around that channel. This minimizes gain stabilization errors. See Chapter 7 for instructions on how to perform instrument background measurements. IMPORTANT: Although the Detective -200 and other standalone Detective instruments have their own background measurement capability, all background measurements for the Detective-Remote System must be performed in the Detective-Remote user interface program. Backgrounds performed in the Detective s standalone program are not used by Detective-Remote. 30

31 4.3.3 LCX (Low-Confidence Expert) Identification Mode Detective-Remote has two radionuclide identification modes: ORTEC Detective -Remote (780490) Standard This posts only threat and innocent IDs made at a high confidence level (this confidence level is also referred to as the Q value). With exceptions as noted, this manual discusses only the standard identification mode. LCX LCX mode displays suspected threat alarms and IDs at a lower confidence level than the standard ID mode. The confidence level is user-selected and can be set between 50 90%. This results in more hits on suspected threat nuclides. Although detection is arguably improved in LCX mode, the false alarm rate will increase to a level which may be unsuitable for many applications. For example, at a 70% setting, the Detective-Remote software will issue approximately two false suspect threat alarms every hour in LCX mode. Therefore, it is recommended that LCX mode be used only by an experienced spectroscopist who can monitor and verify the data. In LCX mode, Suspect ID measurements, events, Signal and Threat Index peaks will have a yellow background. See AppendixA.1 for the suspect messages exclusive to LCX mode. To switch between Standard and LCX modes, go to the Acquisition tab in the Setup and Options Program (for more information see Section 5.3.3). 31

32 4.4 Alarms and Alarm Handling There are four alarm types in Detective-Remote, each with a distinctive background color and unique audio tone or synthetic voice signal. Threat (red) Suspect (yellow; LCX mode only) Innocent (green) Indicates a high-confidence ID of a threat radionuclide. The threat alarm tone sounds, the bottom button bar and Acknowledge button turn red, the back ground for alarm-related events and measurements is red, and red peaks are displayed on the Signal Index and Threat Index graphs. On the Map tab, the detection event is marked with a red triangle. Suspect alarms are generated only in the LCX mode, which is intended for use only by experienced spectroscopists (Section 4.3.3). The suspect alarm signal sounds, the bottom button bar and Acknowledge button turn yellow, the background for alarm- related events and measurements is yellow, and yellow peaks are displayed on the Signal Index and Threat Index graphs. On the Map tab, the detection event is marked with a red triangle. LCX mode has an Elevated radiation or beta ID that indicates the gamma count rate is higher than can be accounted for based on the peaks in the radionuclide library. The implication is that either an unexpected nuclide or a beta emitter is present (beta emitters typically producing counts over a broad range of energies). Move closer to the source and count longer to determine the nature of the suspect item Indicates a high-confidence ID of an innocent radionuclide. The innocent alarm signal sounds, the bottom button bar and Acknowledge button turn green, the background for alarm-related events and measurements are green, and green peaks are displayed on the Signal Index and Threat Index graphs. 32

33 System Error (amber) Each time an ID is posted: Indicates non-radiation errors, such as detector, software, or network problems. The error alarm signal sounds, the bottom button bar and acknowledge button turn amber, and the background for alarm-related events and measurements is amber. On the Detectors tab, the detector status indicator may display one or more system error messages on an amber background. If the error affects the detector subsystem s readiness, the detector status indicator changes to Status: Not Ready. (See also Figure 38) Any number or combination of alarm types can occur simultaneously. When multiple alarms are generated, they are presented highest-priority alarms first (e.g., reds, yellows, greens, ambers). The Alarms tab shows active alarm entries. Alarm background mirrors the alarm color. Even after acknowledgment, they persist until the identified radionuclide is no longer detected by any of the system s detector groups. The bottom of the screen changes color according to the current highest-priority alarm. The color persists until the alarm drops off the Alarms tab. At the same time, the bottom right of the screen displays an Acknowledge button listing the ID or error and mirroring the alarm color. The Acknowledge button remains displayed until acknowledged, even if you exit and restart the User Interface program. Event notification can instead be displayed in a color-coded pop-up box that has an Acknowledge button and comment field. See Figure 13. Click Acknowledge. This logs the alarm as acknowledged on the Events and Alarms tabs. If using the ID pop-up box (Section 5.3.2), you can acknowledge alarms by clicking in either the pop-up box or the Acknowledge button. The ID or error is noted on the Events tab as an event for this survey, and the event background mirrors the alarm color. Until the identified radionuclide is no longer detected by any of the detector groups, the Measurements tab posts once-per-second measurement entries colored according to the highest- priority alarm determined for that time slice. (As discussed in Section 6.2.2, clicking a measurement displays a complete list of all alarms and IDs for that time slice.) 33

34 4.4.1 Acknowledging an Alarm Does Not Clear the Condition That Caused It The radiation condition causing the alarm must be considered present until the detail box for new measurements no longer show it to be present. Once the alarm for a particular ID is acknowledged, the alarm indicator does not reactivate for that ID event. However, if the source is moved away from the detector(s) until no longer detected, then reintroduced, a new ID of the same source could generate another alarm Important Note about False Alarms Because the Detective-Remote software is designed to operate at very sensitive detection thresholds, a Threat alarm may occur from time to time when no threat nuclide is present (typically once every several hours), depending on the ambient background at your site. Acknowledge the alarm(s) and see if it recurs while measuring the same object. If it does not recur, there is typically no need to investigate further (however, your response will depend on your CONOPS). If it does recur for the same object, refer to your site operation procedures to determine the action to be taken. 4.5 Data Collection, Storage, and Management In the Search and Stand-In modes, the Detective-Remote system surveys the space within the detectors FOV for the presence of the radionuclides in the ID library. All spectroscopic data, location data, and analysis results from the survey are saved in a Microsoft SQL Server database, one database file per survey. The maximum database size is 10 GB 10. Each survey database records the following: Raw spectrum data from each detector, collected approximately once per second. The list of the IDs found, along with their confidence values and the detector group(s) and data integrator(s) that produced each ID. The date and time associated with each 1-second data measurement. The Signal Index and Threat Index values (see page 54). The GPS coordinates associated with the data, where GPS signal can be detected. All data necessary to recreate the map interface for all survey measurements and events. 10 To exceed this file size, you would have to perform a continuous, multi-week survey! 34

35 Survey names are assigned to the Survey Database by the system and displayed in the detail box for the survey when you click the Start Search or End Search event for a particular survey (see Figure 6). Survey names cannot be modified, the Review mode lists surveys by date and time, as well as an optional survey Description which the operator may enter (see Figure 60). We suggest assigning informative survey description that, in addition to the date and time, will help you locate the desired survey(s) for review and optionally annotate the contents. Figure 6 Survey Database Name Displayed in the Search Started and Search Ended Event Boxes Data Backup and Management Appendix C tells how to export (back up) and import (restore) Detective-Remote survey database files using SQL Server Management Studio. Database Backup Exporting your surveys is the surest way to produce data backups that can be easily restored. NOTE: While a third-party archival program can be used to copy the analysis computer s entire hard drive, database recovery from this type of backup is difficult and time-consuming. For more information on backing up and restoring large numbers of SQL Server databases, see the Microsoft website 11. Portable Survey Data Exported surveys can be imported and reviewed by anyone with the Detective- Remote suite of software components. Surveys cannot be imported from a newer version of Detective- Remote. Survey files created with an older version of Detective-Remote are updated by the User Interface program the first time you open them in Review mode. 11 There are also third-party SQL Server database backup tools, but ORTEC has not tested any so caution is advised. 35

36 IMPORTANT Other than creating backup sets and archiving your hard drive, do not make any changes to the Detective- Remote database contents. Doing so may cause loss of data. For more information, contact your ORTEC Representative or our Technical Support Group. 4.6 System Cautions and Operating Limitations When positioning Detective instrumentss, securing them with tie-down straps, etc., take care not to bump the touchscreen and change settings, especially the wireless-or-usb radio buttons. Be sure to observe the cautions and limitations with respect to operating conditions, for each of the components in the system. See the hardware manual for details and restrictions for any Detector system. The coolers and detectors are shock-sensitive. Consult the hardware manual for your identifier type for handling recommendations. Protect the system components from prolonged or heavy rainfall and from immersion. On instruments with integral dust caps on the data and power ports, keep all unused connectors capped. You can turn a Detective s cooler off for a brief period (e.g., minutes) without significantly warming the detector. As soon as the cooler is restarted, the computer touchscreen typically shows the word Ready within a few seconds. The cooler can be restarted at any time without harming the detector crystal, regardless of detector crystal temperature. The mechanical coolers for the Detective-Remote detector subsystems are designed for years of continuous operation. We strongly recommend that you leave them on and the detectors fully cooled except during shipping, some storage conditions 12 or maintenance. However, the computer and network hardware can be turned off between surveys, if you wish. The unit can be shipped as soon as the cooler is turned off. There is no need to wait until the detector warms up. Commercial transport regulations require that the internal battery be sealed in its compartment during shipping. Follow the shipping instructions in the hardware manual. 12 Caution: read the hardware owner s manual before storing ORTEC Detective identifiers, in a warm condition, for periods longer than a month. Periodic startup and operation for 1-2 days is recommended on a monthly basis. 36

37 5 STARTUP AND SETUP DETAILS This chapter provides the system startup details for the steps in the Chapter 3 quick-start guide. Preparing the Detective-Remote system for field use requires: Starting the detectors and cooling them to operating temperature. Starting the Detective-Remote computer(s). Establishing wireless or wired USB communication between the computer(s) and detectors. Configuring system parameters such as the number and composition of detector groups, default background count time, and alarm notification options. Pre-caching (seeding) the map tiles for the survey region. Once these steps are completed, you re ready perform a background measurement for the survey site (Chapter 7), then begin radiation monitoring (Chapter 8). NOTE: Except where noted, these instructions are written for the one-computer configuration. If your system uses two computers, all instructions for the User Interface program are run on the user interface computer; all instructions for the Setup and Options and Detective-Remote System Startup programs are run on the analysis computer; and the user interface computer must be connected to the analysis computer s WLAN. 5.1 Start Up and Cool the Detectors 1) Connect each identifier or interchangeable detector module to an external power source as described in the unit s hardware manual. Be sure to note all of the hardware operating conditions and cautions. 2) Power up the Detective -200's computer by pressing the On/Off button at the bottom-right of the touchscreen bezel. The unit will boot up (which may take several minutes) then auto-start the Mobile MCB Server application, which will take another seconds to initialize (during which time the Windows Desktop and other screens will briefly be displayed). 3) When startup is complete, the touchscreen should appear as shown in Figure 7. For wireless systems, the Wireless/ActiveSync radio button on this screen must be marked. For wired systems, the USB Control button must be marked. IMPORTANT: Do not change the factory-set communication mode. This is particularly important if you are using the wireless setting. Changing to the USB mode then switching back to wireless mode may cause the Windows Mobile operating system to reset certain networking characteristics such as the IP address. Any changed settings will need to be restored before the system will function properly. See Appendix B. 37

38 Figure 7 The Mobile MCB Server Screen Indicating USB or Wireless Control. 4) Tap Exit to Windows to exit to the orange ORTEC Launcher interface (Figure 8). Confirm the Mobile MCB Server box is marked to ensure the system self-recovers after power loss. Figure 8 The ORTEC Launcher Screen. 5) From the orange Launcher screen, tap the Detective button. This will take you to the Detective Home Screen 6) The home screen is labeled Survey Mode ( shown in Figure 9). If the Status indicator on the display reads Cooler Off, start the cooler as follows. If the cooler is On, skip to the next step. 38

39 Notes: Figure 9 The Detective Software Home Screen. 7) Referring to the Detective -200's hardware manual, tap the Advanced button to display the first Advanced Setup menu page and tap the button Turn Cooler ON. Within a few seconds, the cooler will start, although you may or may not be able to hear or feel the cooler running. When you tap the Back button to return to the Detective application s Survey Mode screen, the status indicator will read Status: Cooling. 8) There are two ways to monitor detector and hardware status: A) On the Detective s screen. To do the latter, tap Advanced, Status. Until the detector has cooled and the HV has automatically turned on, Detector Temp, Cold Tip Temp, and HV Volt will read ERR, when they have reached operating temperature, they will switch to OK. B) On the Detective-Remote User Interface program s Detector Health tab (6.2.5). On two-computer systems, both computers must be running and connected to the analysis computer s ad hoc network. See the next section for computer startup instructions. A warm Detective -200 typically requires < 14 hours to cool to operating temperature, but may take longer. When the detector reaches operating temperature, the bias voltage will automatically turn on. During the cool down period, ignore any status indicators on the Detective-Remote Idle screen. As noted in the Detective -200 Operator s hardware manual, the internal battery will not charge until the detector has reached operating temperature. After that, the battery will typically reach full charge in 3 4 hours. All background measurements and other functions are handled from the computer s Detective-Remote user interface. 39

40 9) Exit the Detective application by tapping Advanced, Next>>, Next>>, and Exit. This will return you to the orange Launcher screen. Tap Mobile MCB Server to reopen the screen shown in Figure 7, and wait seconds for it to fully initialize. 5.2 Start the Computer(s) and Network Hardware 1) Power up the analysis computer and log into Windows on the Detective-Remote account 13. The factory default Windows password for this account is (all uppercase, no parenthesis) ORTEC. Key system data including the computer login, password, ad hoc network name, network security, network security key, and IP addressing are factory pre-configured and should only be changed in consultation with your ORTEC Representative or our Technical Services Group. 2) For wired systems, you need only login on the computer(s). The wired network icon ( ) will be displayed in the system tray. 3) For wireless systems, the analysis computer does not automatically reconnect to the ad hoc wireless network after reboot so you must manually connect it. On the analysis computer, click the WIFI signal strength icon in the lower-right system tray, then click the network named for the analysis computer s serial number. Figure 10 illustrates the appearance of the system tray as you connect to the network. NOTE: Note that you must also manually reconnect to the network after restarting the computer(s) or if all detectors are disconnected from the network. 4) For the two-computer system, start up the user interface computer, log into Windows on the Detective Remote account, and connect to the analysis computer s ad hoc network. 13 To run any of the Detective -Remote applications from a user-defined account (as distinguished from the factorydefined account), Windows will ask for the Detective -Remote install disk. If you cancel the install prompt, none of the program shortcuts will work. Completing the wizard will fix the shortcuts. 40

41 Figure 10 Click the WIFI Icon and Connect to the Computer s Wireless Network Ready to Run Setup and Options Program 1) When the detectors reach operating temperature, the bias voltage will automatically turn on and self-adjust to the proper setting. 2) If the detectors are communicating with the computer(s), the Detectors and Detector Health tabs in the User Interface program will display the detector status information as the detectors continue cooling. When the detectors are ready to use, the detector status indicators on the Detectors tab will change to Idle status. Acknowledge any errors which may occur. 3) While the detector subsystems are cooling, you can open and run the Setup and Options program to check the system configuration. Just be sure to close DR User Interface and DR Startup before opening Setup and Options. 41

42 5.3 Run the Setup and Options Program The Setup and Options program governs system configuration settings including the detectors to be used; if and how they will be distributed into detector groups; the number and duration of data integrators; how alarms will be presented to the user; and other global parameters. NOTE: The Setup and Options program affects the Detective-Remote system s core functionality and should only be modified by knowledgeable users. The User Interface and Detective-Remote System Startup programs must be closed when this program is running; otherwise, they will not register any changes you make on this page. The default settings for factory-configured systems will typically not require changes, so run Setup and Options only in the following cases: On initial system startup after purchase of a new system. To modify data integration times, detector-group assignments, or reach back settings. To add a new detector module to the system and assign it to one or more detector groups. After upgrading the Detective-Remote software. To acknowledge a significant number of outstanding alarms from the last work session (numerous hardware alarms may accumulate hardware if you use the computer[s] without the detectors, e.g., for survey review). The System Startup program auto-starts each time the computer is rebooted, therefore, the first step is to close it. Click the DR icon,, in the system tray, then click the upper-right corner ( ) on its popup screen. Shutdown takes about 5 seconds. (The Detective Remote User Interface program should already be closed, if not, close it.) Start Setup and Options by entering setup in the Search programs and files box on the Windows Start panel and clicking the Setup and Options search result; or open the going to the Windows Start menu and open the file ORTEC Detective-Remote, then click on Setup and Options. On first use of a new system, check the settings on the tabs as described in the following sections. If adding a new detector module to an existing system, you need visit only the Startup and Detector Groups tabs. You will then be ready to exit the Setup and Options program, click the Close [ ] box, and start the Detective-Remote System Startup and Detective-Remote User Interface programs. 42

43 5.3.1 Server Tab Figure 11 shows the Server tab. IMPORTANT: The System Number, SQL Server Address, SQL Server User ID, and SQL Server User Password entries on this tab are pre-set during system installation. Any changes to these settings will prevent the system from collecting, analyzing, and storing data. Contact your ORTEC Representative or our Technical Services Group if you have any questions about the information in these fields. The Check for upgrade and/or repair button should only be used to activate a new software upgrade or to acknowledge all outstanding alarms from preceding work sessions. The latter can be useful if, for instance, you have generated numerous hardware alarms by using the computer(s) without the detectors connected (for example, to review previous surveys) 14. Figure 11 All Components Found, No Errors; System Ready for Operation. 14 Note that ORTEC service personnel may also instruct you to click this button as part of resolving system problems 43

44 5.3.2 Display Tab The check boxes on this tab (Figure 12) give you options for displaying and annunciating ID alarms; displaying neutron count data; and hiding the Threat Index. Figure 12 The Display Tab. The Show popup on source identification option opens a pop-up box (Figure 13) that parallels the operation of the Acknowledge button (see Secs and ). The box is color-coded according to threat level (red, yellow [LCX mode only], green, amber). The pop-ups persist until acknowledged. If multiple alarms are generated at one time, they are presented highest priority first. Before clicking the Acknowledge button in this box or on the button bar, you may enter a Comment for this event that will be recorded in the Events log. NOTE: If multiple alarms are generated and you enter a comment in a pop-up box, all subsequent popup boxes for this alarm event will display the same comment. Edit or delete it as needed before acknowledging. The auto-text is cleared at the end of the alarm event (so the comment field will be blank the next time a pop-up box opens). 44

45 Synthetic Speech Alarm Annunciator Figure 13 Pop-Up System Error and Innocent ID Alarms. Marking the Use speech output checkbox changes the audio signal alarms for the four threat types to alarms annunciated with the currently selected Windows synthetic speech voice Show Neutron Data This is useful only if one or more of your detectors are equipped with a neutron detector. This adds a virtual strip chart to the Charts tab in the User Interface program Show Threat Index Unmarking this box hides the Threat Index virtual strip chart (also see Section 6.2.6) so that the Charts tab displays only the Signal Index. 45

46 5.3.3 Acquisition Tab The settings on this tab (Figure 14) determine: the ID mode (high- or lower-confidence); the maximum time between background measurements; the default count times for Background measurements and Stand-In surveys whether to suppress or display IDs of NORM (naturally occurring radioactive materials). Figure 14 The Acquisition Tab. 46

47 LCX Mode Low-Confidence Expert Mode is discussed in Section To switch to LCX mode, mark the checkbox and set the slider to the desired confidence level. The data point detail box for each Event displays the LCX mode (disabled/enabled) for the survey and, if LCX mode is enabled, the % of Normal Q-Value Threshold setting (Figure 15). The background color associated with suspect IDs is yellow. Figure 15 LCX Mode and Setting in the Data Point Detail Box on the Events Tab Background Count Preset and Expiration We recommend a count time of at least 30 minutes, 1800 Seconds and the system minimum background count length is 1200 seconds. You may change this preset to any value > / = 1200 seconds (20 minutes). If you end the background count early, before the minimum 1200 seconds, the new background is not saved and the previous background files will be used. If you end the background count early and 1200 seconds has transpired the new background will replace the previous and will immediately be used by the software. The Background expiration is the number of days between required background measurements. If this period is exceeded, all detectors will display expired-background error messages. A new background count must be performed before radiation surveys can be performed Count Preset for Stand-In Surveys Your site operation procedures or your current circumstances will dictate the count length to collect a spectrum for reach back. In Detective-Remote this would be a Stand In Survey. On the Acquisition tab shown in Figure 14, you set the default preset count period. This preset can be changed as needed. Note: Users can stop a Stand-In survey before the preset count time expires, or extend it in increments of 30 seconds as dictated by the circumstances Filter Background NORM IDs The table in Section A.2 lists the gamma peaks which the Detective-Remote analysis engine treats as innocent, NORM background radiation. As discussed in Section 4.3.2, the Background function performs a peak-by- peak analysis to determine the net background count rate for each of these peaks. If the Background checkbox is marked, the net background count rate for each of the NORM peaks is subtracted from the survey spectrum before it is analyzed for alarms. This background filtration step significantly reduces the frequency of nuisance alarms. If you unmark the checkbox, (Figure 17) the NORM peaks are analyzed for alarms without the filtration step Alarms Tab The Alarms tab (Figure 17) has a survey vehicle speed alarm, in miles per hour, and individual control over NORM Identifications, Innocent identifications, Suspect Identifications, and Threat identifications. 47

48 Exceeding Speed Alarm The speed alarm provides an option for users to set a speed alarm for performing surveys. This is very effective in implementing minimum detectible levels of threats during a survey scan. If the vehicle exceeds the Speed Limit, the Acknowledge button and the lower edge of the screen will change to amber, and a system health error will be posted to the Events and Alarms tabs. Slow the vehicle and acknowledge the alarm Alarm on NORM Identifications Figure 16 Acknowledge Speed Alarm. The NORM alarm provides an option for users to set receive an alarm when NORM isotope concentrations have exceeded background limits. This is very effective in adjudication of secondary or separate instrument alarms from handhelds, backpacks etc Alarm on Innocent Identifications other than NORM The innocent alarm provides an option for users to control the alarms for innocent identification while performing surveys. This is very effective in reducing the number of alarms displayed that are a function of testing or when operating in a location with known innocent sources of radiation Alarm on Suspect Identifications other than NORM The suspect alarm provides an option for users to control the alarms for suspect identifications while performing surveys. This is very effective in reducing the number of alarms displayed that are a function of testing Alarm on Threat Identifications other than NORM The threat alarm provides an option for users to control the alarms for threat identifications while performing surveys. This is very effective in reducing the number of alarms displayed that are a function of testing. 48

50 5.3.5 Startup Tab Before setting up detector groups on the Detector Groups tab, use this screen (Figure 18) to choose which Detectors will be active in your detector group(s). Activate them by clicking their checkboxes. These settings can be changed at any time. If a detector is highlighted with red text, it has been part of your Detective-Remote system sometime in the past but is currently not on the MCB Configuration list. If you have temporarily disconnected one or more detectors, ignore the red highlighting and select the detectors (highlighted or not) you intend to use. IMPORTANT The settings in the Programs section of this tab are factory pre-configured for your one- or two-computer system. Do not change these settings without consulting your ORTEC Representative. Changing the GPS Serial Port Number will inactivate the GPS causing a loss of GPS coordinates. Figure 18 Startup Tab Select Detectors. 50

51 Troubleshooting System Configuration Errors If one or more of the Detective s in your system are not listed in the Detectors section of this screen, or if one or more entries are displayed in red: Make sure the missing Detective s are showing the correct connection method either: 1) wireless / active sync or 2) USB Control, on the Mobile MCB Server screen (Figure 7). Check to make sure the GPS is connected and the symbol for the Franson GPS Gate is visible on the Laptop Windows taskbar and is displayed as green not red. With the cursor hover above the DR symbol to see whether either the GPS or Detective instruments has a yellow triangle. For wired USB systems, make sure the cables for missing Detective s are connected correctly, and are not defective. For wireless systems, the Detective Mobile MCB Server display shows a count for instruments and wireless connections. i.e. Instruments: X Connections: X, be sure that it has a 1 under connections. If it displays Connections: 0 the Detective is not communicating with the laptop. On the computer, if the Windows Taskbar does not show a wireless symbol but rather a red antennae, locate and turn on the wireless switch. Click on the wireless symbol, find the computer name click on it and connect if the status is not Connected. Wait seconds to see if communication is established. To check wireless communication setup on the missing instrument (s): o On the Detective, from Mobile MCB Server tap Exit, when prompted answer yes to exit program. The display will return to the orange ORTEC Launcher interface (Figure 8), o From the Launcher tap exit and exit to Windows returning to Windows Mobile o Beneath the START button, look for the blue wireless antennae symbol. o Next to the symbol it should list Wi-Fi: DR-[computer S/N] or (WLAN: ON). o If this is displayed, you should be OK. Go to Start > Launcher to restart the Detective Mobile MCB server program. (alternately you may reboot by holding the power button through the 5 second countdown to initiate a reboot ) o The Mobile MCB Server should auto-start directly to the screen shown in Figure 7. If it goes to Launcher be sure the checkbox beside the Mobile MCB Server button is checked then tap the button. o Confirm the display shows the correct connection method. (wireless / active sync) o Return to the computer(s), reconnect to the LAN as discussed in Section

52 o Repeat this process for each Detective not communicating with DR. If one or more Detective s still cannot be found, but they indicate that they are connected to the DR computer Wi-Fi or LAN o Close DR, o From the shortcut on the Windows Desktop double-click the MCB add new icon. The resulting dialog (which is discussed in detail in the accompanying CONNECTIONS and MAESTRO user documentation) should display all of the Detective s in your system. If the units are identified in MCB add new, close this window and return to DR Setup and Options program (discussed in Sec 4.2.1), select the Startup tab, confirm that all detectors are now displayed, and check the box for the instruments to be used. If any Detective Units are still missing, go to Section 10 to continue troubleshooting. 52

53 5.3.6 Reach-back Tab The Reach-back option lets you specify an Recipient to whom detection event information can be sent from the User Interface program s Events and Reachback tabs. NOTE: All reach-back communications include an N42.42-format.xml file containing the survey and background spectra for each detector in the group that had the highest-confidence identification for the event. As noted at the top of the tab, the default sender is DetectiveRemote@gmail.com, an ORTEC account. To designate another sender, unmark the Use default settings checkbox and complete the fields in the SMTP server settings and Sender settings sections of the screen. Figure 19 The Reach-back Tab. Enter a valid Recipient address and optional Recipient name. If you do not enter these fields, a popup reminder will be displayed when you exit the Setup and Options program. Click No to ignore and close. To send more detailed information about an alarm event, in the Setup and Options tab mark the box for Show Reach-back Questionnaire option. Instead of sending an automatic , the form shown in Figure 20 will open when you right-click an ID event and select it for Reach-back (Section ); or 53

54 will be displayed on the Reach-back tab in the User Interface program. Complete the form and click Save to transmit. You can optionally develop your own reach-back questionnaire based on the default questionnaire, Standard.quest.xml, located in \ORTEC \Detective-Remote in the current user account s AppData folder. To access the default questionnaire, open Windows File Explorer and enter the location %appdata% Figure 20 Default Reach-back Questionnaire. 54

55 5.3.7 Detector Groups Tab Use this screen (Figure 21) to optionally distribute your Detective s into detector groups, to create new detector groups, or to add a new detector module to one or more existing groups. The list of available detectors is based on the instruments activated on the Startup tab. A red detector entry means the detector has been incorporated into the system, but is not currently accessible (it may not be communicating, it may not be checked on the startup page, it may have been removed, etc.). The commands at the bottom of the screen let you add, rename, or remove a group; or listen to the Microsoft synthetic speech module read out group names. Expand each group to display the list of available detectors, mark the checkbox of the detectors you want included in each group. Any detector may be included in multiple groups without limitation. The changes you make to group names here, will display on the Status Graphics tab in Detective- Remote User Interface, (Section 5.3.9). NOTE: Once a detector group is created, you may add or remove detectors at will. It is permissible to completely restructure the type and number of detectors within the group or delete a group and start over. You may find it useful to assign simple group names distinct with their location or area monitored (Left, Right, Forward, Rear, etc.) and simply rearrange their list of detectors, as needed. Figure 21 Adding a Detector Group. 55

56 5.3.8 Integration Times Tab Figure 21 shows the Integration Times tab. Data integrators are discussed and illustrated in Section 4.1. To add a new data integration time, enter the new value in the field at the bottom of the tab, then click Add. To delete an existing integrator, click to highlight it then click Delete. Figure 22 Add or Remove Data Integrators. 56

57 5.3.9 Status Graphics Tab This is the setup screen for the detector group diagram on the User Interface Program s Status tab (see Figure 39). The Status Graphics Tab displays a default vehicle diagram and one rectangular icon displaying the name of each detector group currently defined on the Detector Groups tab. This is an optional feature intended to show which detector group(s) in the vehicle has made the highestconfidence ID of a particular nuclide. In some cases, this information may help you locate a source. However, using or not using the status graphic has no effect on detection, analysis, or IDs. Before setup, the group icons are clustered in the upper-left corner of the tab. Simply click and drag the box with a detector group name to the desired location on the diagram. You may reposition the group icons at any time Using Custom Images Two custom.jpg images (yacht view from above.jpg and SUV view from above.jpg) are supplied with the Detective-Remote software, and may be substituted for the default vehicle diagram. In addition, you may substitute your own.jpg image. Different user accounts can optionally have different Status tab images. To change images: If using your own image, copy it to the Windows clipboard. If using the supplied yacht or SUV images, navigate to the C:\Program Files (x86)\ortec \Detective-Remote folder, and copy the desired image onto the Windows clipboard. In the address bar in Windows Explorer, enter the location %appdata%, Navigate to \ORTEC\Detective Remote to paste the image file into that folder, and rename it to backgroundimage.jpg. Close all Detective-Remote applications. The next time you restart the Detective-Remote System Startup and User Interface applications, the new image will be displayed in the Status tab. The example Status tab images in Figure 23 depict the default vehicle, the supplied yacht image, and an array of Detective -200s for a stand-in or walk-through configuration. Figure 23 Optionally Customize the Status Tab s Detector Layout Diagram. 57

59 Manage Surveys Tab Figure 24 Manage Surveys Tab. Detailed instruction on exporting, deleting and importing surveys is found in Appendix C. 59

60 5.4 The Detective-Remote System Startup Program This application runs in the background and starts automatically each time you reboot the computer. It should only be stopped if a system parameter must be changed in the Setup and Options program. IMPORTANT: If you accidentally close DR Startup program while performing a survey, data is no longer being acquired or saved. Therefore, a gap of unrecorded data will exist in your database until the DR System Startup program is restarted. Because of the data gap, the Survey analysis would likely be considered invalid so the user will want to: End the current survey, launch DR System Startup program, then begin a new survey. To start the Detective-Remote analysis-related programs: Go to Start > type Detective in the Search programs and files box > click on Detective-Remote System Startup or the shortcut for the program you want. Alternately: Start > All Programs> Detective-Remote file > click on System Startup, User Interface or Setup and Options. To view the DR System Startup application; hover over or click on the DR icon ( ) located on the Taskbar. This will display the screen shown in Figure 25. If the GPS antenna or one or more detector(s) are not connected to the analysis computer, the DR icon will display a yellow caution indicator ( ). 60 Figure 25 The Detective-Remote System Startup Tray Application. The pop-up screen displays green, yellow, and red OK/caution/error status icons for the analysis-related programs, GPS server, and system detectors. Roll over a yellow or red icon to see information about the issue. Errors for the Analysis Program and DB Maintenance entries require consultation with our Technical Services Group. GPS Server errors typically indicate that the GPS antenna is not connected to the analysis computer. Any detector that is not connected to the analysis computer or has a current hardware error will be marked with a red or yellow icon.

61 To shut down the Detective-Remote System Startup application, click the upper-right corner ( ) box. Shutdown typically takes approximately 5 seconds. 5.5 Connect and Test the GPS Antenna 1) Connect the GPS antenna to the analysis computer (in two-computer configurations, if you connect the GPS to the user interface computer, the analysis and mapping software will receive no GPS input and the mapping feature will be automatically disabled). The tray icon for the Franson GpsGate GPS server should change from red ( ) to yellow, indicating that the GPS antenna is communicating with the server but does not have a satellite fix. 2) If the Franson GPSGate symbol does not change from red to yellow or green automatically, Close Detective-Remote Startup, close Franson GPSGate, reopen Franson GPSGate and wait for the symbol to turn yellow or green, then reopen Detective Remote Startup. 3) Start the User Interface program by Typing user inter in the Search programs and files box on the Windows Start panel then selecting User Interface. 4) Take the computer and GPS antenna outside and wait for the system to acquire a GPS fix (this will be displayed in the upper right corner of the User Interface screen). The Franson GpsGate icon will change from yellow to green and the DR icon will no longer display the yellow caution indicator. If the FransonGps Gate icon remains red, see the troubleshooting steps in Section ) In Idle Mode, click the upper-right Show... button and select the Map tab to add it to the Idle Mode view. 6) On the Map tab, verify that the map cursor is shown at the current GPS location. 5.6 Ready to Use the User Interface Program The next step is to learn the User Interface program features and use, which are discussed in detail in the next chapter. 61

62 6 USER INTERFACE PROGRAM This chapter discusses the Detective Remote User Interface program features and use. Remember the Detective-Remote System Startup application must be running before the User Interface program will function correctly. To start the User Interface program: or Windows Start> Search programs and files box enter user inter > select User Interface Windows Start > Program Files >Detective-Remote file >select User Interface. On first startup, the User Interface program opens in Idle mode, with the Detectors tab displayed in the left pane and the Detector Health and Events tab on the right. On subsequent startups, it opens in the mode which it was last closed. It is good practice to always close in the Idle mode. Figure 26 shows a system with two detectors, both of which are connected, cooled, and ready for data acquisition. See Figure 38, for examples of status indicators for a detector in various states of readiness and operation. NOTE: Until the detector subsystems are cooled to operating temperature, the status indicators will have an amber error background, and will indicate the detectors are too warm. You may also see background or full-width-half-maximum (FWHM) errors until you perform a background measurement. 62

63 6.1 Main Screen Features Figure 26 User Interface Program Idle Mode, Detectors Ready. Figure 27 illustrates various screen features which may be selected for display. The Events History tab for a survey in progress, displays alarms which have been generated for threat IDs Am-241 and Neutrons on Fe, and innocent IDs Eu-152 and Unknown beta emitter. 63

64 Figure 27 User Interface Screen Features. At initial startup, the Detectors, Detector Health, and Events tabs are displayed. 64

65 To open additional tabs, simply click the upper-right Show button and select from the available entries (Figure 28). The list of available tabs changes with the operating mode, e.g., Search, Idle, etc. (see the table on the next page). In each mode (Idle, search, Stand In, Background, and Review) the tab arrangements are independent. This allows you to choose which tabs to display, as well as how they are arranged and their size on the screen (for detail see Section 6.3). Figure 28 Tab Selections. The following table summarizes the tabs available in each operating mode. IDLE SEARCH STAND IN REVIEW BACKGROUND Detectors T T T T T Measurements T T T - Events T T T T T Alarms T T T T Detector Health T T T T T Strip Charts T T T - Status T T T - Map T T T T T Spectrum T T T - Reachback T T T Features Common to Multiple Tabs Function Tabs The function tabs shown in Figure 29, display real-time detector status and count-rate information; current radionuclide IDs; a graphic representation of the detector group(s) contributing to the ID; a continuous stream of all event and measurement information stored on the analysis computer during the survey; and a continuous stream of state of health information for each detector. 65

66 These functions are discussed in greater detail in Section 6. Figure 29 The Function Tabs. Each mode (Idle, Search, Stand-In, Background, Review) has its own selection and arrangement of default tabs. Add as many as you wish from the tab selection list (see Figure 28), and arrange them as needed (Section 6.3). When opening a new tab, it opens on top and to left of currently open tabs. If the user interface footprint is too narrow to display the names of all the open tabs, those that not displayed are listed on a tab list. Click the arrow icon to open the list, and select the tab you wish to display. (Figure 30). Figure 30 Hidden Tabs Indicator. The Detectors, Detector Health, and Alarms tabs always represent the live system state (never the review survey state). The Measurements, Events, Map, Strip Charts, Status, Spectrum, and Reach-back tabs always represent the current survey status (i.e., review in Review mode and live in Survey mode). The Map tab has reduced function mode when in Idle mode Button Bar These buttons control data acquisition and review. Different modes display different buttons. Figure 31 shows the button bar in Idle mode. It allows you to (create) a new mobile Search, stationary Stand-In survey, start a Background count, Review an existing survey, or add a Comment to the Pop Up Alarm and Event Log Figure 33 below (also see section ). Figure 31 Start Surveys, Backgrounds, and Reviews; and Add Comments to the Event Log. 66

67 Alarm Acknowledgement Button Each time an alarm is generated, the ID is posted in the Acknowledge button in the bottom right corner of the screen. Figure 32 shows the Acknowledge button for a nuclide ID and a detector state-of-health error. If multiple alarms are posted at the same time, they are presented highest priority first. As you acknowledge each one, it is removed from the bottom right of the screen. If the Show pop-up box on source identification option is marked in the Setup and Options program, (see section ), a pop- up box opens at the same time the Acknowledge button is displayed (Figure 33). If you wish to enter a comment tap the comment button, type a comment, then click Acknowledge in the pop-up box or on the button bar to close both alarm windows. Figure 32 Acknowledge Button. Figure 33 Acknowledge the Pop-Up Alarm. 67

68 Data Point Detail Box The Events and Measurements tabs have a data point detail box. This indicator: Tracks each new data point in the current search, updating about once per second Shows the information for a data point chosen from the Events or Measurements tab in either the current survey or when reviewing a past survey. In an active survey, this area updates in real-time unless you click a specific data point on one of the tabs. Doing this stops real-time tracking and displays analysis or other event-related details for the selected point. To resume real-time updates, click the Track Latest button at the upper right of the screen. Figure 34 shows the data point detail box for the Measurements tab. Figure 34 Data Point Detail Box Measurements Tab. The upper fields show the Point number, acquisition date and UTC time, GPS Location, and gamma and optional neutron count rates. The lower section shows the IDs for this data point, their associated alarm colors, the data integrator, and the detector or detector groups which generated each ID. Figure 35 shows examples of data point detail boxes on the Events tab. Figure 35 Data Point Detail Box Events Tab. 68

69 EVENT-TYPE FILTER LIST available with the EVENTS, REACHBACK, AND MEASUREMENTS TABS The Events, Reach-back, and Measurements tabs have a filter list in the upper-right corner (Figure 36). Events tab Filter for Information (non-alarm events), Operator Entries Only (Pop-up box comments), system alarms, or radionuclide ID alarms, all alarms. Reachback tab Filter for radionuclide ID alarms. Measurements tab Filter for radionuclide ID measurements. Figure 36 Event-Type Filter List for the Events, Reachback, and Measurements Tabs Data Synchronization Across Tabs The Measurements, Charts and Status tabs are always synchronized with one another. During a survey, single- or double-clicking an entry on the Measurements or Events tabs suspends realtime tracking on all but the Map tab (which has its own Auto-Tracking feature; see Section ). While suspended the measurements and events are recorded and continue to accumulate, but you must scroll down to see them. To return to real-time tracking, click the Track Latest button. Double-clicking an ID event on the Events tab scrolls the Measurements tab to the highest-confidence measurement for that ID; aligns the corresponding entries on the Status, Charts, and Spectrum tabs; and repositions the map to select the ID event. On the Map tab, double-clicking the popup window for an ID event performs the same synchronization as double-clicking an ID event on the Events tab. Double-clicking in the pop-up for a measurement selects the corresponding measurement on the Measurements tab, and aligns the corresponding entries on the Status, Charts, and Spectrum tabs, but has no effect on the Events tab. 69

70 6.2 Function Tabs Detectors Tab This tab displays a status indicator for each detector in the system and displays real-time data including: Detector number and description. Operation mode of the system (idle, search, stand-in, background). Real-time gamma count rate, gamma dose rate, detector % dead time, and optional neutron countrate meters. These meters change from green to yellow to red as count and dose rates increase. A battery status indicator, and an electrical plug symbol if a detector is connected to external power. System error/status messages (see Section 10.5 for troubleshooting errors). The type of system error determines the color of the background. Note that as long as the indicator background is white, the detector can be used for surveys. If the background is pink, the detector is out of service. Figure 37 is a Detector Status Indicator showing a detector in Idle Mode. Figure 37 1 DR-8066J in Idle Mode. 70

71 The next figure, Figure 38, shows a variety Detector Status Indicator boxes displaying different count rates. Also pictured are examples of comments which may be displayed on the bottom of the Detector Status Indicator. Figure 38 Detector Status Indicator and various status messages which may be displayed on the bottom of the status indicator box Removing a Detector from the system After a detector is added to the system, its status indicator will stay on the Detectors tab until you delete it. Even when a detector has been removed from all detector groups and is no longer listed in the Setup and Options program. The indicator for a disconnected detector is amber and says Not Communicating. This is the same whether the detector is in a detector group and not communicating or if it has been removed from the system but still shows up on the detector tab. If you wish to delete it from the Detectors tab, place the cursor over the Detector Status Indicator, rightclick and choose Delete. Should you accidentally delete the indicator for an active detector that is amber because it is not communicating, it will automatically appear in the display when the detector resumes communication. 71

72 6.2.2 Measurements Tab The Measurements tab (location shown on the left side in Figure 39) displays a chronological list of all system measurements for the currently open survey, newest data point at the bottom. The order of measurements displayed is the same whether this is a count in progress or an existing survey in Review mode. Figure 39 User Interface Program Measurements and Status Tabs. Measurements can be filtered by type; select a filter from the drop list symbol located directly above the right corner of the measurement list (Section ). Information about the currently selected measurement in the list is displayed in the data point detail box. Also the associated point will be displayed on the Charts tab, and on the Status tab. In an active survey the measurements update in real-time until you click on an entry. Clicking an entry suspends the real time aspect of the display while you view the point you have selected. To resume realtime updates on this tab, click the upper-right Track Latest button and it will skip forward to the current measurement. Note that Figure 39 also shows the Status tab, which presents a depiction of the search vehicle. For the selected measurement #28 in this figure, the highest-confidence-level ID (Q = 10.8) was made by the detectors in Group 1 so the Group 1 indicator is highlighted in the Status tab. 72

73 6.2.3 Events Tab The Events tab (shown on the right side in Figure 40) displays a chronological list of all survey events, newest entry at the bottom. The list includes: search start and end, stand-in start and end, background start and end, IDs, alarms, system errors, and comments added via the pop-up ID alarm box. Event information and the associated N42.42-format spectrum files can be sent from this tab via reachback as discussed in Sec Figure 40 User Interface Program Events Tab. There are four (4) alarm states on the Events tab: Alarm State Description of Alarm State Active The alarm condition still exists and has not been acknowledged by an operator. Unacknowledged The alarm condition has ended but an operator has not acknowledged the alarm. Acknowledged The alarm condition has been acknowledged and still exists. None (blank) The alarm has ended and has been acknowledged. The events can be filtered by event type with the drop list at the top right corner above the tab (refer to Section ). During a survey, the event list updates in real-time until you click a particular event to display its data point details. All real time updates to measurements, events and alarms are suspended until the user clicks the Track Latest button at the upper right of the tab. 73

74 Alarm events are posted both to the Events and Reachback tabs and can be sent to Reachback from either tab Send to reachback Figure 41 Sending Alarm Event Information and Spectra to Reach- back Recipient. This information is pre-defined on the Reachback tab as discussed in Setup and Options (Section 5). This function is available from either the Events tab or the Reachback tab but only while using the Survey and Review modes. To learn more about using the Reachback tab, see Section Right-click the event of interest, select Send to Reachback (Figure 41), and confirm that you wish to your Reachback contact information about this event. Included in this will be the N format survey and background spectra for each detector in the group that posted the highest-confidence ID for the event. If the Show Reach-back Questionnaire option is enabled in the Setup and Options program, the form shown in Figure 20 will open in a popup window. Fill it out according to your operating procedures and click Save to transmit. Reachback events are sent one-at-a-time. The questionnaire attachment is named Reach-back questionnaire.xml and the N42.42 filename is based on the radionuclide identified. For example, spectra for identification of U-235'.xml. If you are sending multiple reachback events to the same recipient, questionnaires and N42.42 files with the same filename must be renamed to avoid overwriting the previous file sent. 74

75 6.2.4 Alarms Tab The Alarms tab (Figure 42) is a quick visual reference to all outstanding alarms. This tab is similar in layout to the Events tab except that it only shows Active, Unacknowledged, and Acknowledged alarms. The Duration field tracks the length of time an alarm is present. Figure 42 User Interface Program Alarms Tab With Acknowledged and Unacknowledged Alarms. 75

76 6.2.5 Detector Health Tab When the System Startup program is running, all properly connected and communicating detectors are polled sequentially every 10 minutes and the results displayed on the Detector Health tab (Figure 43). In addition to polling date and time and detector name, the state-of-health information includes parameters such as bias voltage, detector temperature, gain stabilizer settings, detection mode (e.g., Idle, Search, Background, etc.), the cooler s elapsed run time since the most recent startup, gamma and neutron count and dose rates. Any detector that is included in the system configuration but not connected generates an alarm but does not create a health record since it is not communicating and therefore cannot transmit information. Figure 43 Detector Health Tab. 76

77 6.2.6 Charts Tab Signal and Threat Indexes The Charts tab displays the Signal Index and Threat Index, and the optional Neutron Count Rate chart (see Figure 44). These virtual strip charts can indicate nearby radioactivity even before IDs and alarms are generated. Both charts scroll from right to left with time, providing short-term data trends. Keep in mind that these are indirect indicators meant as quick visual tools, not count-rate or dose-rate meters. NOTE: The most recent point on the charts always reflects the current measurement on the Measurements tab. During a survey, to see the most recent measurement update in real time, click the Track Latest button at the upper right of the Measurements tab. Figure 44 Charts Tab Signal and Threat Index Strip Charts for Am-241 and Neutron Alarms. The Signal Index is based on the sum of the net gamma count rate from all detectors for all detected radionuclides. The peak height on this chart increases as you move the detector subsystem(s) closer to a gamma source. When an alarm is generated, the section of chart for that time interval is assigned the same color as the alarm. For simultaneous alarms, the chart displays the color of the highest-priority alarm. The Threat Index is a function of the maximum confidence factor for all threat nuclides in the library, and always reflects the highest-confidence ID of threat nuclides from any one detector. Threat nuclides include U, Pu, Np, Am, and neutrons (see also Appendix A). The peak height on this chart increases as you move closer to a threat material. The Neutron Count Rate chart is only displayed if you select the Show Neutron Data option in the Setup and Options program (not all Detective series instruments have a neutron detector). 77

78 Figure 44 shows an ID and alarm for the threat IDs Am-241 and Neutrons on Fe. Note that the Signal Index indicates a relatively weak radiation source, while the Threat Index and Neutron Count Rate chart reflect a high probability that the source includes threat nuclides as well as a neutron emitter. NOTE: The most recent point on the charts always reflects the current measurement on the Measurements tab. During a survey, to see the most recent measurement update in real time, click the Track Latest button at the upper right of the Measurements tab Status Tab Detector Group Diagram Figure 39 shows the Status tab, which provides a visual representation of your search vehicle and detector array for each measurement in a survey. For each measurement associated with an alarm, the detector group with the highest-confidence-level ID is highlighted with the corresponding alarm color, as shown in the figure. The appearance of this tab is configured in the Setup and Options program (see Section 5.3.9) Map Tab The Map tab (Figure 45) displays real-time measurement locations and detection events on almost any map system. Figure 45 Map Tab Features. For location data to be collected and displayed on the Map tab: The map tiles for the current survey area must be seeded (pre-cached) on the analysis computer to make them available on the Map tab, unless you have internet access during the survey; (see Section 9.3). The GPS antenna must be connected to the analysis computer and receiving satellite data or no mapping data will be collected (however, all other survey data will be available). For instance, if you pass through a tunnel and lose GPS signal, the breadcrumb trail on the map will be interrupted until the GPS signal is restored. 78

79 Toolbar The toolbar at the bottom of the map (Figure 46) controls the major map features. The Settings button on the left lets you customize the appearance of the breadcrumbs and detection zones (Section 9.1). These changes can be made at any time in any mode that displays the Map tab. Figure 46 Map Toolbar. The next button is the droplist of available maps (the default Street Maps is shown here). The third button lets you choose the measurement type being tracked by the breadcrumbs. Use the Show/Hide Layers to control display of the data layers. Auto Tracking determines whether or not the map automatically repositions as the detector group changes location 15. When all entries on the list are disabled (unmarked), you can pan to any point on the map. Note that this auto-tracking feature is independent of the tracking feature for the other tabs. 15 In most systems, all detector groups will be mounted in the same monitoring vehicle. However, as long as all groups remain in range of the analysis computer s WLAN, they can be parsed into one or more vehicles and /or stationary arrays. Consult your ORTEC Representative for more information. 79

Click and Drag Click on the map and drag the mouse to pan the map location. Double Click Double click on a specific point on the map to zoom in one level. Shift + Double Click While holding the shift key, double click on a specific point on the map to zoom out one level. Keyboard Navigation Arrow keys Pan across the map. Plus (+) Key Zoom in one level. Minus (-) Key Zoom out one level. 80

81 Data Markings There are four map icons / indicators types: Location The car -shaped location icon marks the current position of the search system. Measurement The survey path and analysis results are represented by measurement icons frequently referred to as breadcrumbs, which represent one of the five Detective-Remote measurement types: 1) Gamma count rate (cps) 2) Gamma dose rate (mrem/hr) 3) Signal index 4) Threat index 5) Neutron count rate (cps) Single breadcrumbs represent one measurement (approximately 1 per second). Double breadcrumbs represent two or more measurements, depending on the map zoom level. The default breadcrumb color is light blue; Figure 45 shows bread-crumbs color-customized to the Threat Index value. Hover over a breadcrumb to display its Measurement information in a pop-up (Figure 47). This pop-up displays information about each measurement under the breadcrumb. To see all measurements under the breadcrumb, click View All. Double-click a measurement to synchronize it with the corresponding entry on the Measurements tab. 81

82 Event Marks the location at which an alarm was generated with a triangle. For nuclide IDs, it marks the measurement at which the highest-confidence ID was calculated by the analysis engine. You can customize the color of the triangular ID event icons (Section 9.1). By default, innocent ID events are blue ( ) and threat ID events are red ( ). Hover over an Event icon to open its Event information popup (Figure 48). This popup lists information about each event under the triangle. To see all events under the triangle, click View All. Double-click an event to synchronize it with a corresponding entry on the Events tab (Figure 49). Detection Zone, Field of View diagram Optional diagram of the detector group FOV for ID events. This is an aid for locating the source. The color and extent of the detection zone can be customized to your preferences (Section 9.1).

84 6.2.9 Spectrum Tab Use the Spectrum tab (Figure 50), together with the Measurements tab, to view a specific detector s spectra and optionally generate.chn-format survey and detector background spectrum files. We recommend arranging the screen with the Events and Measurements tabs (also, optionally, the Reachback tab) stacked together on one side and the Spectrum tab on the other. To create a spectrum: Choose a Detector from the droplist, Figure 50 Spectrum Tab. Double-click the measurement number at the end of the desired data slice, Enter the desired Duration in seconds, and the spectrum window will display the summed spectra from the start time to the Measurement time. (The start time is the measurement time minus the duration, in seconds) The Display options allow you to adjust the color and vertical scaling. 84

85 Creating Spectrum and Background Files for any Measurement ORTEC Detective -Remote (780490) Detective-Remote lets you generate ORTEC.CHN format spectrum and background files for any system detector or detector group. This can be done in either the Survey or Review modes. The procedure involves locating a particular measurement, loading its information into the Spectrum tab, selecting a specific detector, and choosing how much data (in terms of detector live time) to include in the.chn file. As noted above, we recommend arranging the screen with the Events and Measurements tabs (and optionally, the Reachback tab) stacked together on one side and the Spectrum tab on the other. Note that you can also generate N42.42-format survey and background spectra for your own use by sending yourself a reachback . See Section ) On the Events tab, double-click an ID event of interest. This will synchronize the Events and Measurements tabs such that the latter highlights the measurement with the highest cumulative Q value for the event. The measurement s detail box will list the data integrator(s), group(s), and Q value(s) for each radionuclide ID made during that measurement. The measurement time in the Date column will be the ending live time for the.chn file. 2) On the Spectrum tab, select the desired Detector and enter the Duration of the data slice you wish to save in the.chn file. The maximum duration is the measurement time minus the survey start time. 3) Return to the Measurements tab and double-click the measurement to load the time slice into the Spectrum window. NOTE: If no spectrum is displayed, try increasing the Duration and doubleclicking the desired measurement again. 4) Click Save and select the Destination Folder. Each save operation creates the specified spectrum file plus the detector s currently valid background spectrum. These files can be viewed in MAESTRO or its accompanying WINPLOTS spectrum plotting application. 5) To create a.chn file with a different Duration, enter the new value, return to the Measurements tab and double-click the measurement again, then Save. 6) To create a.chn file from a different measurement, enter the desired duration, go to the Measurements tab and double-click the desired measurement, then Save. 85

86 Figure 51 illustrates this process, starting with identification of an event of interest on the Reachback tab. The.CHN file contains 30 sec of data starting at 5:32:54 pm and ending at the measurement time. NOTE: As of this release of the User Interface program, the Reachback tab is not synchronized with the Events tab. Therefore, switch to the Events tab, locate the desired event and double-click it, then work between the Measurements and Spectrum tabs as described above. 86 Figure 51 Create.CHN Files for the Selected Measurement and Duration.

87 Spectrum File Naming Convention The naming convention for survey spectra is: DR[sysno][surveytype]-[database].YYYYMMDDhhmmssUTC.det[#].[dur]Sec.chn Where: DR[sysno] is the Detective-Remote system number (for users with more than one system on the same computer[s]); surveytype is Search or Standin; the database name is displayed in the Unique ID column in the Review dialog (Figure 65); YYYY is the acquisition year, MM the month, DD the day, hh the hour (UTC), mm the minutes, ss the seconds; # is the detector system number (described below); dur is the Duration in seconds, where the number of digits is 3 or more (i.e., all times from seconds are expressed in 3-digit format). The convention for background filenames is: DR[sysno][surveytype]-[database].det[#].bkg.chn Where: bkg indicates this as a background file for the indicated database and detector. The detector system number (#) is shown on the Detector listbox on the Spectrum tab, and reflects the order in which the instruments were added to the system, not the detector names and numbers displayed in the Setup and Options program and MCB Configuration. Example: Figure 51 shows that this measurement was collected during a Search on March 11, 2014, at 5:33:24 pm Eastern Standard Time. The spectrum for Detector 1 was saved, and the Duration setting was 30 seconds. Given the database name 56531ffe-a3ab cf5-56ee6932e069, the resulting.chn files are named: DR1Search-56531ffe-a3ab cf5-56ee6932e UTC.det1.030Sec.chn DR1Search-56531ffe-a3ab cf5-56ee6932e069.det1.bkg.chn The files in the example above, the first file is the search spectrum and the second one is the Detector 1 background file. 87

88 Reachback Tab The reachback settings are selected / defined in the Setup and Options program (see Section 5.3.6). This tab, on the left side of Figure 52, is available in the Search, Stand-In, and Review modes, and displays the list of events that can be sent to a reachback recipient. Figure 52 Reachback Tab. If you select an event for reachback and no Recipient information has been entered in the Setup and Options program, a window will open in which you can enter recipient information. The information you enter at this time will subsequently be saved / displayed on the Reach-back tab in Setup and Options for future use. A reachback transmission always includes an N42.42-format file containing the survey and background spectra for each detector in the group that generated the highest-confidence ID for the selected event. If the Show Reach-back Questionnaire option is enabled, the questionnaire will be displayed below the list of events. Otherwise, the lower section of the tab will be blank, and only a brief description of the event will accompany the N42.42 file. 88

89 The questionnaire attachment is named Reach-back question- naire.xml, and the N42.42 filename is based on the radionuclide identified, for instance, Spectra for identification of U-235'.xml. Reachback events are sent one-at-a-time. If you send multiple reachback events / alarms to the same recipient, and the questionnaires and N42.42 files have the same filename, they must be renamed to avoid overwriting prior attachments. When finished entering information, Click Send. 6.3 Rearranging the Tabs The User Interface program lets you choose which tabs will be displayed in each mode, as well as their grouping, order, and size. You can make any tab a new tab group simply by clicking the tab name and dragging to one of the five destination hotspots left, right, up, down, center illustrated on the layout guide, which appears as soon as you start dragging a tab (see Figure 53). This guide allows you to specify where you want the tab to be positioned with respect to other tab(s). If you drop the tab on the right side of the guide, you will position the tab to the right of other tab(s). The same is true for the top, bottom, and left positions on the guide. If you drop the tab in the center of the guide the tab will be stacked with the other tab(s). You can also undock a tab and allow it to float. The following figures demonstrate tab regrouping. Figure 53 The Layout. 89

90 Figure 54 shows the Alarms tab being moved to the right side of the window, according to the following instructions. 1) Click and drag a tab until it undocks from the others. This will display the layout guide. 2) Move the undocked tab to the desired part of the screen then, still holding down the left mouse button, roll the mouse arrow over the desired hotspot on the layout guide. The corresponding part of the screen will change color. 3) Release the left mouse button and this tab will form a new tab page arrangement. 4) To add another tab to the new arrangement, drag it over the new group, roll the mouse arrow over the center hotspot on the layout guide, and drop the tab. 5) Click and drag tab names within a group to rearrange them left to right, and click and drag the boundaries of the groups to adjust the size of the various elements. 6) To ungroup, simply drag all tabs over the same section of the screen and drop them in the guide s center position. Figure 54 Grab the Alarms Tab and Regroup It on the Right Side of the Window. 90

92 7 BACKGROUND MEASUREMENTS This chapter describes how to perform background measurements to minimize both nuisance alarms and detector gain stabilizer errors. See Section for a conceptual overview of the background NORM filtration technique employed by Detective-Remote. 7.1 General Guidelines Your site operating procedures should determine how frequently and when to perform background measurements as well as how long to count. However, the following are best practices and we strongly recommend their incorporation in your site procedures. IMPORTANT All background measurements must be performed within in the Detective-Remote program. Backgrounds performed in the identifier s standalone user interface program are not used by the Detective-Remote program. Perform a background measurement each time the system is moved to a new site. This will reset the Detective -200's gain stabilizer and determine the local net background count rate for each of the NORM peaks listed in Section A.2. The Default count time preset and Background expiration period are on the Acquisition tab in the Setup and Options program (Section ). The minimum background count time is 1200 seconds (20 minutes). However, we recommend a minimum count time of 1500 sec (30 minutes) for best system performance. If a Detective is turned off, warmed above operating temperature, and re-cooled, you must run a new background which will automatically center the K-40 peak in the factory-set calibration channel and zero the gain stabilizer around that channel. If you use a Detective as soon as it cools to the maximum operating temperature, perform a background before use. After a few hours, when the detector is cooled to the operating set point, run another background to reset the gain stabilizer. If at any time a Detective posts a gain stabilizer or FWHM (full width at half maximum) error, note the detector temperature and cooler drive voltage as discussed in the hardware manual, and run a new background to reset the gain stabilizer. If the error recurs, consult your ORTEC Representative or contact ORTEC Technical Services Group. 92

93 IMPORTANT If you are operating where there is little or no naturally occurring K-40 (for instance, at sea), we strongly recommend the use of a K-40 source (e.g., a low-sodium salt substitute containing potassium chloride). If K-40 is absent during a background measurement the gain stabilizer is disabled, and remains disabled until another background is performed with K-40 present. Operating with the gain stabilizer off can reduce system performance. 7.2 Performing the Background Measurement 1) To start a background measurement, remove all nearby radiation sources (except an optional K- 40 source) and click the Background button. Figure 56 shows a count in progress. Figure 56 Background Measurement In Progress. 2) Check the detector indicators to ensure all are counting. If one or more detectors are still in Idle mode, click End Background then restart the count. If all detectors do not start counting, begin troubleshooting network and detector problems (start at Section 10). 3) The background routine performs one or more adjustment cycles to re-zero the gain stabilizer aligning the 1460 kev K-40 peak. The current adjustment cycle is displayed in the detector status indicator, as shown in Figure 56. After the final adjustment cycle the background is performed. If one detector in a multi detector system requires multiple adjustment cycles, the background count time restarts for all detectors after the final adjustment cycle. 93

94 4) If you wish, you can extend the count time by clicking the Add 5 minutes button as many times as desired. (Note that you can only use this feature before the count time elapses; i.e. you cannot restart a completed background measurement and add more count time to it.) 5) To manually abort a background count, click End Background. If the minimum count has not elapsed yet for all detectors, an are you sure? dialog will open (Figure 57). If you abort now, the previous set of background spectra will remain in use until the next background measurement is completed. Note : If the Background expiration period specified in the Setup and Options program (Section ) has transpired, you must complete a new background measurement before the system will enter Survey mode. If you abort after the minimum count time has elapsed, the new background measurement will be put into effect. When the are you sure? dialog opens, click End Now. Figure 57 Abort Background Measurement or Continue? 6) When the background count reaches the count preset (or is manually stopped after the minimum1200 seconds have elapsed for all detectors), the user interface and detector status indicators will return to Idle mode. The comment for the BKG Ended event will list the number of cycles and total count time for each detector in the system (Figure 58). Figure 58 Background Measurement Information on Event Tab. 94

95 7) The new background data for each detector will be stored in the system database on the analysis computer, and will be used in all data analysis until the next background measurement is performed. 7.3 Viewing the Detector Background Spectra To generate a detector s background spectrum in the.chn format, see Section

96 8 SURVEYING FOR RADIATION This discussion assumes that all Detective-Remote System Startup software components are running during the entire survey. If for any reason the Detective-Remote System Startup program is closed during a survey, see Section 10.1for recovery instructions. If a detector stops communicating, see Section 10. If the User Interface program is closed during a survey, simply restart it. 8.1 Starting a Search or Stand-In Survey To start a survey, click Search or Stand-In (Figure 59). Figure 59 Start a Survey. The top left of the screen will switch from the System Is Idle display to the Collecting Search or Collecting Stand-In header. Figure 60 Enter Optional Description. An optional search description field will be displayed to the right of the Collecting... header (Figure 60). We recommend an entry, in addition to the timestamp, which will help you locate older surveys for review. An entry in this field will be displayed with the search date and time. The description can be changed any time during the survey or in Review mode. When the search is started, the status indicators on the Detectors tab will switch from Idle mode to the mode selected, (Search, Stand In, Background, or Review). If you have selected the Strip Charts Tab from the Show menu to be displayed, the strip charts on the Charts tab will begin scrolling from right to left. At the same time, new measurements will begin posting on the Measurements tab. Search Figure 61 depicts a Search in progress. The screen is arranged into three tab groups displaying the Maps, Charts, and Measurements tabs. Note the unacknowledged alarm for Am- 241 at the bottom of the Event History list. This ID is reflected by the Signal Index and Threat Index, as well as the Acknowledge: Am-241 button. To end this survey, click End Search. Stand-In Figure 62 shows 3 screen shots of selected screen features from the Stand-In survey. Note the countdown timer below the Collecting Stand-In header. To end the survey before the preset count time, click End Early. To extend the length of the Stand In survey, click Add 30 Sec. To extend the count you must do this before the end of the preset count length. 96

97 The count length may be extended as many times as needed, as long as it is extended before the time ends. LCX Mode Figure 63 shows a Search performed in the LCX mode (Section 4.3.3), in which low- confidence IDs are posted as suspects on a yellow background. Note that the data point description for each Event includes the LCX setting. Figure 61 IDs and Alarms during a Search (Standard ID Mode). Figure 62 Stand-In Survey screen features. 97

98 Figure 63 IDs and Alarms shown are during an LCX Mode Search Adding Comments to Pop-Up Alarm Boxes If the Show popup box on source identification option is marked in the Setup and Options program, you can enter a comment for alarm notifications. Comments are saved to the Events log of the survey. Figure 64 shows the pop-up alarm box for a Eu-152 alarm with a comment noting where the ID was made. Note that the Event log shows a comment has been entered for this ID event. Clicking the event displays the comment text. 98

99 Creating Spectrum and Background files for a Detector ORTEC Detective -Remote (780490) See Section Note also that you can generate N42.42-format survey and background spectra by sending yourself a reachback . See Section Review Mode Figure 64 Adding a comment to the Event Log. Review mode allows you to view any survey stored on the analysis computer. You can optionally generate survey and background spectrum files, detection event information and spectra to a reachback contact, and add or edit the survey description. In addition, this dialog enables you to identify survey database files for export, as well as review imported survey databases. See Appendix C. To locate a survey for export, click the Review button to open the Review Survey dialog (Figure 65), locate the desired survey, and view the survey s Unique ID. To review a survey, scroll to the desired survey and double-click it or highlight it and click Open all tabs except Alarms are available in this mode. As you move through the entries on the Measurements tab (by clicking on a measurement or press the up/down arrow keys), the strip charts, Status tab, and data point detail box will display the data for each measurement (Figure 66). Other data synchronization features are discussed in Section Double-click an event or measurement to load the relevant map tiles. 99

100 IMPORTANT If you review a survey for which the map tiles are not cached on the analysis computer, for instance, an imported survey or a survey in which you accessed the OSM map in real-time via a cellular modem, you must connect the computer to the internet and either access the ORTEC web-based map server in real time, or pre-cache the surveyed area s map tiles for offline review. Otherwise, the Map tab will not display the survey s map data. If an alternate map system has been loaded on the analysis computer (computer 2 on a dual computer system), no internet connection or pre-caching is required. Figure 65 Choose a Survey for Review. To generate measurement and detector background files in the ORTEC.CHN format, see Section On the Map tab, you may change the color of the measurement types, detection zones, and event icons as needed to better visualize the survey data (see Section 9.1). Reachback information can be sent from the Event and Reachback tabs. See Sections or

101 NOTE: Should a live system error occur while you are in Rreview mode, the live Acknowledge button (and Alarm popup, if configured) will activate and the interface will turn amber, however, you will not see the alarm on the review Events tab. This is because you are reviewing the events from a stored survey. When you exit Review mode, the live Events tab will display the error entry. Figure 66 Reviewing the Charts and Measurements from a Past Survey. 101

102 9 MAPPING Detective-Remote uses the powerful, versatile Sensor Portal Mapping Platform to generate real-time maps during your mobile surveys. The mapping function displays route, measurement points, and the location of any ID events. This chapter tells how to customize your maps, how to add and configure an alternative map source to the analysis computer, and how to pre-cache (seed) map tiles for field use. For more detailed instructions on the Sensor Portal s extensive capabilities, see the accompanying Sensor Portal and Map Control, User Guide. 9.1 Customizing Your Map Graphics This section tells how to change the default appearance of the event icons, measurement breadcrumbs, and detection zone graphics on the Map tab in the Detective-Remote User Interface program. The Settings menu on the toolbar, (Figure 67), is the access point for these options. All colors and settings can be changed at any time from the Map tab in the User Interface program. NOTE: Colors are not saved with the survey data. Rather, the current color settings are applied when you review a survey. Figure 67 The Settings Menu. 102

103 9.1.1 Edit Event Colors This function (Figure 68) lets you change the color of the five Detective-Remote event levels, e.g., Low, Normal, High, Urgent, and Immediate (no other settings can be changed). Detective-Remote uses the Normal level for innocent ID events and Immediate for threat ID s or in LCX mode for suspect IDs. To change the Event colors, first select the desired measurement type from the map toolbar, then click Settings / Edit Event Colors. After making changes Click OK to accept and save any changes or Cancel to exit without saving changes. Figure 68 Edit the Event Icon Color. 103

104 9.1.2 Edit Measurement Colors The default breadcrumb for all five measurement types is a medium blue. To change color, first select the desired measurement type from the map toolbar, then click Settings / Edit Measurement Colors. To change the breadcrumb color, you must create at least one entry in the Choose Measurement Colors dialog, shown on the left in Figure 69. If no initial entry has been defined in this dialog, click the +Add button. This will open the Set Measurement Threshold dialog (right side, Figure 69). Figure 69 Change Breadcrumb Color and/or Create Color Gradient. NOTE: Set the threshold value (at the top of the dialog) to zero. Otherwise, measurements that fall below your lowest threshold will be the default blue. Click the desired color on the color wheel and click OK to return to the Choose Measurement Colors dialog. The new entry will be displayed as a thumbnail of the color and threshold value, along with Edit and Remove buttons. 104

105 You may add as many entries as you wish. For example, Figure 70 shows a five-color gradient for the Threat Index. Figure 70 Creating a Color Gradient. Click OK to accept any changes or Cancel to exit without changes. NOTE: As of this release, Remove entries from the end (bottom) of the list; otherwise, the User Interface program may lock up or crash. If this happens, simply restart the User Interface and return to the Map tab. 105

106 9.1.3 Edit Detection Zones This screen lets you customize the color and extent of the detection zone indicator displayed on the map with each ID event icon. All existing detector group sensors are listed on the Detection Zone Configurations screen (left side, Figure 71), and depict the orientation of the detection zone as the survey vehicle points up (i.e., in the same direction as the vehicle/array graphic on the Status tab). Figure 71 Configuring a Detector Group s Detection Zone Graphics. Click the Change button for any group to access the Detection Zone Configuration screen. To change the color, click the desired spot on the color wheel. To adjust the zone size and extent, click the Settings tab. Use the Arc Width slider and Depth field to adjust the size of the zone (typically, this will be based on the maximum detection distance and detector group FOV). Then use the Angle slider to orient the detector group FOV with respect to the survey vehicle/array. Click OK to accept any changes or Cancel to exit without changes. NOTE: We recommend setting the Min. Display Speed to zero. Otherwise, if the survey vehicle is traveling below the minimum speed when an ID event occurs, the detection zone for that event will not be marked on the map. 106

107 Note that overlapping detection zones combine each zone s color and opacity. Figure 72 illustrates this for the three detection zone colors shown on the left in Figure 71. Figure 72 Detection Zone. 9.2 Adding Alternate Map Layers to Detective-Remote This section is applicable only if you will be using a map source other than the default Open Street Maps. IMPORTANT Alternate map layers are stored in their entirety on the analysis computer. Therefore, if you intend to use only your added map layers, rather than the default OSM, there is no need to connect to the internet and download a cache of map tiles from the map server before going into the field. However, if you plan to use the OSM as well as your own map(s), you must pre-cache as discussed in Section ) Before starting if the User Interface program is running, close it. 2) Obtain the alternate map data. This data will likely be in one of the following formats: Directory of spatial files (shapefiles) ArcGrid PostGISGeo TIFF PostGIS (JNDI) Gtopo30 Properties ImageMosaic ShapeFile WorldImage Web Feature Server WMS 107

108 3) Copy the alternate map data to the following folder (Figure 73): C:\Program Files (x86)\geoserver\data_dir\data Figure 73 View of Alternate Map Folder. 4) Start the Mapping Setup interface by typing map in the Start Menu Search programs and files box and select Mapping Setup from the search results. Or select: Start > All Programs > Sensor Portal > Mapping Setup This will open the GeoServer map server interface in the default web browser (Figure 74). Figure 74 Log In to GeoServer. 108

109 5) At the top of the Welcome screen, log in using the following credentials (all lowercase). Username: admin Password: geoserver After login, the Welcome screen will appear as in Figure 75. Figure 75 Logged In. 6) In the Data section on the left sidebar, click Stores (Figure 76). Figure 76 Begin Setting Up New Data Store. 109

110 7) At the top of the screen, click Add new Store (Figure 77). Figure 77 Add New Data Store. 110

111 8) Click the appropriate data source hyperlink. In this example, (Figure 78), the ShapeFile - ESRI link in the Vector Data Sources section has been selected. Figure 78 ShapeFile selected. 111

112 9) In the Basic Store Info section, enter the appropriate Data Source Name (USA_Roads in our example) and optional Description. Then, in the Connection Parameters section, click the Browse link and navigate to the Shapefile location (in our example, file:data/usa_roads.shp). The screen will appear as shown in Figure 79. Figure 79 Enter the Data Source Name and Location. 112

113 10) At the bottom of the screen, click the Save button. The resulting screen will look similar to Figure 80. Figure 80 Alternate Map Source Ready to Publish. 113

114 11) Under the right-hand Action column, click the Publish link. This will display the Edit Layer screen shown in Figure 81 (note that each map is treated as a layer). 114 Figure 81 Enter the Coordinate Reference System and Bounding Box Parameters.

115 12) Enter the following information: In the Coordinate Reference Systems section, enter the value EPSG:4326 in the Declared SRS field. NOTE: This value is valid for most maps that are compatible with Detective- Remote. If you obtain unexpected results, contact our Technical Services Group. In the Bounding Boxes section, click the Compute from data link under the Native Bounding Box and Compute from native bounds link under the Lat/Lon Bounding Box. 13) At the bottom of the screen, click the Save button. Your new map source will now be added below the default OSM map entry. The example in Figure 82 shows the addition of the USA_Roads data source. Figure 82 New Map Source Added. 115

116 9.2.1 Registering the New Map in Sensor Portal Now that your map (layer) has been linked to the GeoServer interface, you must make it available to the Sensor Portal interface. To do this follothese steps: 1) The first step is to ensure you know the new map s name, including uppercase and lowercase letters, symbols, etc. To do this, click Layers on the left sidebar to open the Layer Preview screen. The new layer s name will be displayed in addition to the name of the default Open Street Maps. In the example shown in (Figure 83), the new entry is Maps:USA_ roads. Figure 83 Maps:USA_roads. 116

117 2) Start the Sensor Portal interface by entering sens in the Search programs and files box on the Start panel. Select the Sensor Portal search result. Or Start > Program Files > Sensor Portal. It may take several minutes for the interface, shown (Figure 84), to load into the web browser. Figure 84 Sensor Portal Interface. 117

118 3) Click the red Administration tab (Figure 85). Figure 85 Select Administration. 4) Click the System Settings icon to display the screen shown in Figure 86. On first use, it may take several seconds for this screen to open. On the right side of the Map Layers section, click the +Add link. Figure 86 System Settings. 118

119 5) In the Add Map Layer window (Figure 87), enter the following information: ORTEC Detective -Remote (780490) Enter a descriptive Display Name for this layer (our example: USA Roads). From the Layer Type droplist, select the WMTS Layer entry. NOTE: This layer type will be valid for almost all maps compatible with Detective-Remote. If you obtain unexpected results, contact our Technical Services Group. In the URL field, enter the following URL seen below, be sure to correctly spell the lowercase, 13-character server name detective-rmt:. o In the Layer Name field, enter the name identified in step (1) of this section (in this example it was Maps:USA_roads ), be certain that the name is entered exactly as written in Step 1. The remaining fields can be left blank. Figure 87 Add Map Layer. 119

120 6) Click the Add button in the lower right corner. Figure 88 shows the new entry USA Roads in the area labeled Map Layers. Figure 88 New Map Layer Added to List. 7) To confirm the new layer is correctly registered in Sensor Portal, click its corresponding Preview/ Seed link. After a few seconds of initialization, verify that the preview dialog shows the map contents (Figure 89). Figure 89 Preview Displays New Map. 120

121 8) Close the GeoServer and Sensor Portal interfaces by exiting the web browser. ORTEC Detective -Remote (780490) 9) The next time you start the User Interface program, the lower-left corner of the Map tab will display a droplist menu in the lower left corner as shown in Figure 90. This droplist will contain all the available map layers. You may switch between map layers at any time. Figure 90 New Map in User Interface Map Tab. 121

122 9.3 Seeding (Pre-Caching) Maps Detective-Remote mapping requires you to pre-cache or seed the analysis computer with a targeted set of map tiles for your area(s) of interest when connected to the internet 16. You can seed maps without exiting the User Interface or System Startup applications. Each time you prepare to survey a new region, you must pre-cache its map tiles from the map server. Once you have downloaded map tiles for a particular area, they are retained on the analysis computer for use without reseeding. The map cache is located in the C:\Program Files (x86)\ GeoServer\Data_dir\gwc folder. The time required to download map information depends on the size of the area, the level of map detail you request, and the speed of your internet connection. It can take from several minutes to many hours. A little experimentation will show you the amount of time required to download the map data needed for your next set of surveys. If time is a factor, a good way to test the speed is by seeding less detailed maps first. Add more detailed layers as needed or as time allows. IMPORTANT Seeding requires internet access. For wired systems, you may connect via any means, wired or wireless. For wireless systems, connect via wired eethernet, or a Bluetooth or wired USB tether. If you connect to another wireless network, in almost all cases the current ad hoc network s fixed IP address will be incompatible with the other network. In such cases, Windows will offer to automatically fix the problem. If you allow this fix, Windows will switch the computer to dynamic IP addressing and erase the fixed IP address. You must restore the ad hoc wireless network s fixed IP address (Section B.5) before you can reconnect to the Detective-Remote system. To pre-cache map tiles: 1) Connect the analysis computer to the internet. 2) Launch the Sensor Portal interface by entering sens in the Search programs and files box on the Start panel then selecting the Sensor Portal search result (or select Start > Program files > Sensor Portal). It may take several minutes for the interface to load in the default web browser (Figure 84). 16 Unless you have real-time internet access in the field via cellular modem or tethering to a mobile phone. 122

123 3) Click the red Administration tab (Figure 85), then on the lower-left select System Settings icon to display the screen shown in Figure 91. Figure 91 System Settings Screen. 123

124 4) In the Map Layers section, click the Preview/Seed link for the desired map (Street Maps in the example figure). This will open the map preview window (Figure 92). Figure 92 Pan and Zoom to Display the Desired Map Area. 124

125 5) Click and drag (or use the arrow keys) as needed to pan the mapto your area, then click the +/- buttons in the map window to zoom in until the desired survey area is bounded by the preview window (Figure 93). Figure 93 Right-Click to Open Menu, then Select the Map Detail Level to Begin Seeding. 6) Right-click the map window to display the popup menu shown in Figure 93, then click on the level of map detail to be downloaded. Most users select the Seed everything (very slow) option. Map seeding will start immediately. 7) Right-clicking on the Preview map will display the seed progress as a percentage. The Abort button is located below the progress indicator. If seeding takes too long, you may abort at any time. This will return you to the map preview window. Select a smaller map area or a lower level of detail and try again. 8) When seeding is complete, close the web browser and disconnect the system from the internet. The seeded map content will now be available offline. 125

126 10 TROUBLESHOOTING 10.1 If You Close an Application or Sleep the Computer During a Search Closing the User Interface does not affect an in-progress survey (or a review or background measurement). Simply restart the application. Closing Detective-Remote System Startup program is interrupted during a survey, either by accidental program shutdown or by putting the computer in sleep mode, when the program is restarted, the survey will still be in Search mode and will register the survey as being in progress. However, there will be a gap in the data corresponding to the amount of time both programs were not jointly operating and this gap may render the analysis invalid. The survey must be stopped and restarted. 1) If the Detective-Remote System Startup program was accidentally closed: a. End the survey b. Restart the System 2) If the computer was put into sleep mode: a. End the survey b. Close both programs c. Reboot the computer(s) d. Reconnect the analysis computer to its ad hoc network e. Reconnect the user interface computer and detector modules to the network f. Restart the System Startup g. Restart the User Interface programs. In all cases, the virtual strip charts on the Charts tab will show no interruption in the data even though a gap does exist. The gap will be evident on the Measurements and Events charts. 126

127 10.2 Wireless Issues, Detective (s) or Computer Not Responding ORTEC Detective -Remote (780490) Actions that interrupt communication between the analysis computer and one or more detectors: Allowing the computer to enter a sleep/hibernate/power-saving mode. Restarting the computer. Running the MCB Configuration program. Clicking the Check for upgrade and/or repair button on the Setup and Options program s Server tab while the System Startup application is running. Connecting the computer to another WLAN, which will delete the wireless adapter s fixed IPaddress. Moving one or more detectors out of range of the analysis computer. 1) Check the Detective (s) that is/are not responding to ensure that the Mobile MCB Server screen is displayed on the touchscreen (Figure 7) and the radio button for your system s connection method (Wireless/ActiveSync vs. USB Control) is selected. 2) If your wireless system has been switched to the USB Control setting, tap the Wireless/ ActiveSync radio button then restart the system as follows: a. If all of the Detective s have left the network, reconnect the computer(s) to the ad hoc network according to Section 5.2. b. Restart the disconnected Detective -200(s): Press and hold the Detective s On/Off button for 1 3 seconds to display the power menu, then tap the Restart option (If the Detective does not respond to a quick press of the On/Off button, press and hold the button for about 30 seconds until the unit reboots.) Restart takes a few minutes, after which a series of screens including the Windows Mobile desktop will briefly be displayed before the Mobile MCB Server screen is presented. The connection method you selected before restart will still be selected (reboot does not change it). 3) For a USB system: a. Confirm the USB Control radio button is displayed on the Detective s touchscreen. b. Ensure all cables have continuity and are connected correctly. c. There is no need to restart the computer(s) or Detective (s). 127

128 4) If using a wireless system, the network connection may have failed. This occurs when: a. The computer is rebooted b. After running the MCB Configuration program (which is typically done only to add a new detector to the system or troubleshoot a detector that does not show up in the system configuration test), c. If you accidentally run the Setup and Options program while the Detective-Remote System Startup application is running. i. To recover restart the Detective -200 computer as discussed in 2) b) above, then reconnect the computer to the network according to Section 5.2 of this manual. 5) Very infrequently a Detective s Windows Mobile operating system stops responding to external commands. a. To recover, restart its computer as in 2) b) above GPS Issues (Franson GpsGate Icon is Red) When the Franson GpsGate GPS server is running and the GPS antenna is connected and receiving satellite input, the Franson GpsGate icon in the system tray should be green ( ). When the GPS antenna is connected but does not have a satellite fix, the icon is yellow and the DR icon is flagged with a yellow caution indicator. In all other cases, the icon is red ( ). 128

129 If connecting the GPS antenna does not change the icon to yellow or green: 1) Disconnect the GPS antenna. 2) Right-click the Franson icon and select Settings from the context menu (Figure 94). Figure 94 Franson Conext Menu. 3) In the Set input from where data is received section of the Settings dialog, click the Close button. The button name will change to Open.

135 B. ADDING DETECTORS TO YOUR SYSTEM This appendix tells how to add ORTEC identifiers and interchangeable detector modules to an existing one or two computer Detective-Remote system. NOTE: Most of this can be done with just the computer(s) and the new detector(s) i.e., if your existing system is mounted in a search vehicle, there is no need to sit in the vehicle to perform most of the procedure. B.1 Supported Instruments This Detective-Remote release supports the following ORTEC instruments and connection modes: Wireless or Wired USB Detective -100 T(firmware DETF-305 or later) Detective -200 (DX and EX) Detective -X Detective-TDM micro-detective (including HX and DX) Wired USB Only ICS IDM-200, IDM-200-V LDM (firmware DETL-010 or later) Micro-trans-SPEC (including UF6) trans-spec-100 T(firmware TSDX-305 or later) B.2 Required Materials and Resources All necessary software and firmware upgrades are available from ORTEC. The hardware manual for the detector module. For wireless configurations, the current release of the ORTEC Mobile MCB Server. For all configurations, the current release of the ORTEC Connections Driver Update Kit (P/N ). B.3 System Checks and Software Upgrades For a two-computer configuration, perform these system checks and software upgrades on both computers unless otherwise indicated. B.3.1 Ensure All Power-Saving Settings are Disabled In the Windows Control Panel Power Options utility, ensure all power-saving and sleep/hibernate options for the display, hard disk, wireless adapter, processor, USB ports, and all other computer components are set to Never/Disable/Off for both plugged in and battery power sources. This will prevent interruptions of data acquisition and wireless communication. 135

136 B.3.2 Ensure ORTEC CONNECTIONS v8.04 or Later is Installed This release of Detective-Remote requires CONNECTIONS v8.04 or later to mediate communication between the ORTEC detectors and the system computer(s). If CONNECTIONS is already installed on your computer(s). Check the version by opening Windows Explorer, navigating to C:\Program Files (x86)\common Files\ORTEC Shared\UMCBI, then hovering the mouse pointer over the mcbcon32.exe application to display its File version, as shown in Figure 95. Figure 95 Check the CONNECTIONS Version. If necessary, obtain the latest CONNECTIONS Driver Update Kit (P/N ) from your ORTEC representative or our Technical Services Group. Install according to the update kit s instructions, noting the following: 1) Accept the default installation location. 2) On the Instrument Setup screen, select the USB-based instruments option. 3) To conserve computer memory resources and CPU time, unmark the Allow other computers to use this computer s instruments checkbox (unless you have a specific need to share the system detectors with other network computers). B.3.3 If Adding a Newly Purchased Detector New identifiers and detector modules are shipped with the latest version of CONNECTIONS and MAESTRO, both of which must be installed (on both computers in two-computer systems) in order to obtain full performance from your new instrument. Install these new applications first, according to their installation instructions. 136

137 B.4 Add New Detectors B.4.1 Detector Modules without an Integrated Computer These instruments the IDM-200, LDM, and ICS can only be connected via wired USB. Power the module on, then cable it to the analysis computer. In most cases, Windows will install the instrument by itself. However, if the Found New Hardware wizard opens, complete it according to the instructions in the module s hardware manual. Then return to Section 3 of this manual and continue installation and configuration. B.4.2 Portable Identifiers with Integrated Computer These instruments the Detective -200, micro-detective (including HX or DX), Detective EX or DX-100, Detective EX or DX-100T, trans-spec-100, trans- SPEC-100T and Micro-trans-SPEC (including UF6) support both wireless and wired USB connections. 1) For wired configurations, refer to the hardware manual (and the following content) and switch the identifier to the MCA (spectroscopy) mode, then connect the identifier to the analysis computer via USB cable. After the hardware installation routine has completed, upgrade/install Mobile MCB Server, then go to Section 3 and continue installation and configuration. 2) For wireless configurations, go to Section B.5.1 and upgrade/install Mobile MCB Server. Then go to Section B.5 for instructions on assigning the identifier a fixed IP address and connecting to the analysis computer s ad hoc wireless network. B.5 Wired Configurations Install the Identifier on the Analysis Computer In wired configurations, portable identifiers must be in the MCA (spectroscopy) mode, as distinguished from the ActiveSync or Data (standalone identifier/data transfer) mode. Refer as needed to the identifier s user manual. 1) For Detective -100 and trans SPEC-100 units, connect the rear-panel CONTROL port to the analysis computer with a USB cable. 2) For Detective -200s, micro-detective series units (including HX and DX), and Micro-trans- SPEC series units including UF6, navigate to the identifier application s USB control or communication screen and tap the MCA Mode radio button. Then connect the unit to the analysis computer with a USB cable. 3) In most cases, Windows will install the new identifier by itself. However, if the Found New Hardware wizard opens, complete it according to the instructions in the identifier s hardware manual. 4) You are now ready to go to B.5.1 and install Mobile MCB Server. 137

138 B.5.1 Upgrade Mobile MCB Server on all Identifiers NOTE: If you have also purchased new ORTEC spectroscopy applications for your identifier(s) e.g., the Micro-Detective, trans-spec, or UF6 application install them first and Mobile MCB Server last, otherwise the new Mobile MCB Server version may be overwritten. 1) The Mobile MCB Server program (P/N ) is supplied on an SD card. Install it according to its accompanying instruction sheet, and update all other identifiers in your system so all are using the latest Mobile MCB Server and Launcher. 2) Referring to the identifier s user manual, restart its computer. Boot-up may take several minutes. The Mobile MCB Server will then auto-start, and will take seconds to initialize (during which time the Windows Desktop and other screens may briefly be displayed). 3) When startup is complete, the Detective touchscreen should appear as shown in Figure 7. 4) For wired systems: a. Detective -100 and trans SPEC-100 units Disconnect the identifier from the analysis computer, tap the USB Control radio button on the touchscreen, then reconnect (the rearpanel CONTROL port) to the analysis computer. i. NOTE: To switch this type of identifier from wired USB connection to wireless, disconnect from the analysis computer first, then tap the Wireless/ ActiveSync radio button on the touchscreen. b. All other identifiers Tap the USB Control radio button on the touchscreen (no need to disconnect the USB cable). i. Tap Exit to Windows. This will display the Launcher screen (Figure 8). ii. Confirm that the Mobile MCB Server checkbox is marked to ensure the system self-recovers after power loss. iii. Restart Mobile MCB Server and go to Section B ) For wireless systems, tap the Wireless/ActiveSync radio button on the touchscreen. i. Tap Exit to Windows. This will display the Launcher screen (Figure 8). ii. Confirm that the Mobile MCB Server checkbox is marked to ensure the system self-recovers after power loss. iii. Restart Mobile MCB Server and go to Section B

139 B.6 Wireless Configurations Connect to the Ad Hoc Wireless Network B.6.1 Confirm the Wireless Network Connection Settings Before assigning fixed IP addresses to the new detector(s), confirm wireless network adapter settings for the computer(s). NOTE: If your IT department assigns IP addresses for your network devices, the computer (or both, in a two-computer system) will need an Internet Protocol Version 4 (TCP/IPv4) IP address and subnet mask. 1) If connected to a wired network, disconnect the Ethernet cable from the computer. 2) Start with the analysis computer. In the Windows Control Panel, open the Network and Sharing Center utility (Figure 96). Figure 96 Open Network and Sharing Center. 139

140 3) On the next screen s left sidebar, click Change adapter settings (Figure 97). Figure 97 Change Adapter Settings. 140

141 4) Right-click Wireless Network Connection (Figure 98), then select Properties to open the dialog shown in Figure 99. Figure 98 Select the Wireless Network Connection Entry. Figure 99 Properties Dialog. 141

142 5) Make sure the checkboxes for all items except Internet Protocol Version 6 (TCP/IPv6) are marked as shown in Figure 99, then double-click Internet Protocol Version 4 (TCP/IPv4) to display its Properties dialog (Figure 100). Figure 100 Set IP Address. 6) Confirm the following IP address settings for the analysis computer: IP address Subnet mask ) Click OK twice. 8) From the Control Panel, reopen the Network and Sharing Center utility and select Change adapter settings from the left sidebar. 9) Right-click the ad hoc wireless network connection and select Connect/Disconnect. 10) Find the new ad hoc network s listing. If not connected, click the new entry then click Connect. 11) You may wish to record the IP address(es) for the computer(s) s wireless adapter in a text file on the analysis computer for easy access/recovery. To connect the computer to another network, we recommend using wired Ethernet, or Bluetooth or wired USB tethering. 142

143 12) In two-computer systems, repeat for the User Interface computer, except that the IP Address in step (6) above, should be (i.e., increment the last digit in the fourth triad from 100 to 101). B.6.2 Assign a Fixed IP Address to the New Identifier(s) NOTE: If your IT department assigns IP addresses for your network devices, each identifier being added to Detective-Remote will need an Internet Protocol Version 4 (TCP/IPv4) IP address, subnet mask, and gateway; and these must be compatible with the IP address(es) assigned to the computer(s) in the preceding section. Most ORTEC identifiers use the Windows Mobile 6.1 Classic operating system; however, some early units used v6.0 Classic, which in places used slightly different tab, button, and screen names. These are noted in parentheses 17. 1) The analysis computer must be within range and connected to its ad hoc wireless network. 2) On the identifier, exit all currently running ORTEC applications including any spectroscopy applications, Mobile MCB Server, and Launcher. 3) Turn on the identifier computer s wireless adapter: On the Desktop, tap the Start button, then the Settings entry, Tap the Connections tab Tap the Wireless Manager icon to display the Wireless Manager screen If the Wi-Fi (or Wireless LAN) button indicates the adapter is Off, tap to enable it. The button will change from pale to bright green (blue), and the name of a wireless network may be displayed below the button. Tap Done to return to the Connections tab. 17 At a glance, the v6.1 Desktop is green and v6.0 is blue. To confirm the operating system version, tap Settings, System, About. 143

144 4) Tap the Network Cards icon to display the Configure Network Adapters screen (Configure Wireless Networks screen, Network Adapters tab). Tap the entry for the wireless card (Marvell SDI08686 Wireless card). This will open the setup screen. If your Detective-Remote system was factory-configured as a wireless system, its original identifiers should already have fixed IP addresses starting with for Detective 1, for Detective 2, and so on; i.e., only the last triad in the address changes, incrementing by 1 for each subsequent identifier. All original detectors should all be using the factory-assigned Subnet and Gateway address ; and all new detectors will use these same settings. For the first identifier you add to the system, assign the next IP address in the series. That is, if the original system has four Detective s, your first additional identifier, unit 5, should be assigned NOTE: If your organization has more than one Detective-Remote system, assign an IP address that has not yet been used in either system. This will make it easy to transfer Detective s from one system to another. Enter the factory system s Subnet entry, , and Gateway entry, Tap OK twice to return to the Connections tab. 5) Repeat the preceding steps for all new detectors, incrementing the last digit of the IP address by 1 (.6 for unit 6, etc.), and using the same Subnet and Gateway entries for all detector modules. 6) You may wish to record the above settings for each identifier you add to the system, and save them in a text file on the analysis computer for easy access/recovery. B.6.3 Check Network Communication Test each new identifier s network connection by pinging it from the analysis computer. 1) On the Windows Start menu, type cmd in the Search programs and files box, and select the CMD search result. This will open the command window (Figure 101). 144

145 Figure 101 Open the Command (CMD) Window. 2) At the C:\Users\DETECTIVE-REMOTE> prompt, type ping followed by a space, then the first new detector s IP address (in our example in the preceding section, this would be detector 5's IP address, ). 3) Study the ping report and verify the computer and detector are communicating (Figure 102). Figure 102 Ping Successful. 4) If communication fails, repeat the steps in Section B.6 to confirm the identifier s IP address, then ping again. 5) If communication still fails, use wired USB as a secondary connection method (see Section B.5 for setup). Otherwise, consult your IT department or ORTEC Technical Services Group for assistance. 145

146 6) Repeat for each new detector. When all new units are communicating successfully, proceed to the next section. B.6.4 Run the MCB Configuration Program The next step is to run the MCB Configuration program from the MCB add new shortcut on the desktop to establish communication between the analysis computer and the new detectors, wired and wireless. This step has already been completed for the Detectives in factory configured systems. However, when you add more detectors to the system, the MCB Configuration program must recognize them before they are available in Detective-Remote. NOTE: If you change an identifier from wireless to wired connection, or vice versa, you must re-run MCB Add New in addition to the setup steps discussed in the preceding section. IMPORTANT When adding a new detector module(s) to the system, always run MCB Add New from the desktop shortcut. Do not add new detectors from the MCB Configuration instance on the MAESTRO menu. This is because MCB Add New has the -P flag added to the MCB Configuration command line. This flag lets you run MCB Configuration without all system detectors connected to the analysis computer. Doing this allows you to take your analysis laptop or tablet out of the survey vehicle and into a building or other workspace to add a new detector(s) to the system. If you run MCB configuration from MAESTRO (without the -P flag) and do not have all detectors connected, the disconnected detector units will be removed from the Detective-Remote system. To restore them to the system, you will need to reconnect them to the system in their wired or wireless configuration, then run MCB Add New to add them back into the system. 1) On the Windows desktop, double-click the MCB Add New desktop shortcut. The resulting dialog (discussed in detail in the CONNECTIONS and MAESTRO user documentation) should display all of the Detective s in your system. 2) New instruments will initially be assigned the ID Number zero (0), which must be changed to a unique, non-zero number. For units in a wireless system, you may find it helpful to use the last digit of the IP address as the detector number. To do this, double-click the new detector s entry and manually assign it a unique number. (For additional instructions on customizing detector Numbers, see the CONNECTIONS Driver Update Kit documentation.) 3) IMPORTANT: Do not click the RENUMBER ALL button and do not renumber identifiers that have already been configured in the Detective-Remote Setup and Options program. If you accidentally renumber previously configured units, rerun MCB Configuration, double-click on each mis-numbered detector, and restore its original number. 146

147 4) If you permanently remove a detector from the system and want MCB Configuration and Setup and Options to reflect that removal, connect all remaining system detectors to the computer(s) and run the MAESTRO instance of MCB Configuration (without the -P flag). When you do this all detectors not connected to the system will be removed from the MCB Configuration. This also will subsequently remove them from Startup and Detector Groups tabs in the Setup and Options program. B.7 Confirm New Detectors are Available in Detective-Remote You are now ready to confirm the new detector(s) have been correctly integrated into Detective-Remote. 1) Mount the new detectors in the search vehicle, and connect all system detectors to the analysis computer by wireless LAN or wired USB. 2) Referring to Sections 3.5 and 5.3, close the System Startup program and start Setup and Options. 3) Go to the Startup tab (Section 5.3.5) and verify that all existing and new detector(s) are listed. If any are missing, refer to Section 10 to troubleshoot computer/detector connectivity. If all detectors are present, go to the Detector Groups tab (Section 5.3.7) and assign them to detector groups. 4) Return to Section B.8 below to source-test the new detectors. B.8 Source Test the Detectors We recommend that you obtain one or more Exempt Quantity gamma sources for testing your equipment. Typically used sources include Co-60, Cs-137, Ba-133, Am-241, or Tl-208 and if you have neutron detectors in the system which you wish to test you may want to look into purchasing Cf-252 source. Test the system using the Stand In survey mode to perform source ID test on the individual detector and detector groups. 147

148 B.9 Note: Temporarily Using an Identifier in Standalone Mode You can optionally remove a standalone identifier (e.g., Detective - or trans-spec series unit) from the Detective-Remote system to take a closer look at an object of interest. Wireless configurations To dismount the instrument from the detector array, exit the Mobile MCB Server, then start the desired identifier application. When ready to return the identifier to the Detective-Remote system, simply exit the identifier application, restart Mobile MCB Server, remount the unit checking the Wireless/ActiveSync option is still marked on the Mobile MCB Server screen. Wired configurations Disconnect the unit from the USB cable, dismount it from the detector array, exit the Mobile MCB Server, then start the identifier application To return the unit to the Detective-Remote system, exit the identifier application, restart Mobile MCB Server, and remount as USB Control, re-cable the unit to the analysis computer, and make sure the USB Control radio option is still marked on the Mobile MCB Server screen. *** Your identifiers are now successfully integrated into the Detective-Remote system. *** 148
