2 Hall-C Analyzer Overview Hall-C ROOT Analysis framework (HCANA) is written in C++ and is an extension of the Hall A analyzer podd Based on previous Fortran Analyzer ENGINE infrastructure Hall C ROOT Analyzer Wiki Maintained on GitHub Users fork off of develop branch Contributions are made in local/remote personal repository of HCANA Changes are pushed back onto the development branch which (may) get merged into the development branch Detailed "How-To" wiki: instructions how to Git started with HCANA and GitHub 2

3 Steps to Install HCANA 1. Download and install ROOT (> 5.32) 2. Setup ROOT environment source /path/to/rootbuild/bin/thisroot.(c)sh 3. Fork hcana repository (if you have not already done so) 4. Clone personal remote repository on local machine git clone 5. cd into hcana directory and setup the environment source setup.(c)sh 6. Obtain the podd submodule which hcana points too git submodule init git submodule update 7. Create new branch and switch to it git checkout -b branch-name 8. Build HCANA scons -j4 "How-To" wiki ROOT Analyzer/Compiling Wiki ROOT Analyzer/Running Wiki 3

5 Work Flow of HCANA HCANA utilizes the Hall-A podd decoder to unpack raw EVIO data into THaEvData objects Each readout module (F250, 1190, ) has its own decoder class podd/hana_decode THcHitList utilizes the detector maps to associate the ROC, slot, & channel number with a specific detector THcHitList::DecodeToHitList(&THaEvData) THcDetectorMap builds an array (ftable) with one structure element per readout channel THcDetectorMap::Load(const char *fname) Each element holds the roc, slot, channel number and module type for a given channel In addition, the element holds the id number of the detector, the plane, the counter (or wire number), and the signal number (ADC/TDC, +/-) Raw EVIO Data THaEvData THcHitList Data 5

6 Work Flow of HCANA At initialization each detector class has its detector map populated with the list of readout channels belonging it ghcdetectormap->fillmap(fdetmap, idstring) In addition, a hit list is created to hold the raw hits for each respective detector THcHitList::InitHitList(fDetMap, rawhitclassname, maxhits) Detector classes then decode the THcHitList data into raw hit data associated with a specific detector s readout channel THcDetector::Decode(&THaEvData) Raw hit information is stored as TClonesArray objects which are accessible via THcAnalyzer adcpulseampraw, adcpulseamp, THaEvData THcHitList Raw Hit Data Raw Hit Data 6

7 Work Flow of HCANA Raw hit data is further processed into higher level hit data objects via fiducial ADC & TDC cuts THcDetector::CoarseProcess(&TClonesArray) goodadcped, goodadcpulseint, Hit data can then be further processed into higher level physics data THcDetector::FineProcess(&TClonesArray) Fiducial tracking cuts e.g. χ 2 /ndf, β, E/p Track matching, efficiencies, Raw, hit, & physics data is then processed by THcAnalyzer which makes the data available via ROOT histograms and TTrees Raw Hit Data Hit Data Physics Data 7

8 Hall-C Replay Framework designed to facilitate the reconstruction of events in the Hall-C spectrometers The Hall-C Replay Strucutre Wiki provides general information regarding the infrastructure The Hall-C replay code is maintained in the JeffersonLab/hallc_replay GitHub repository Interfaces with THcAnalyzer to process and obtain the data Raw, hit, & tracking data Physics data 8

28 Hall-C Replay: Interactive Demonstration Goal: Acquire detector data from SHMS KPP run 484 from the hodoscope, drift chambers, heavy gas Cherenkov, trigger apparatus, and the golden track 1. Produce a TTree with all possible data from the three detector systems, trigger apparatus, and golden track 2. Produce 1D histograms of the for the hodoscope S1X+ raw, pedestal subtracted pulse amplitude, and pulse time variables 3. Produce a 1D histogram of the S1X+ pedestal subtracted pulse amplitude with a cut on the number of reconstructed tracks in the chambers = 1 4. Produce a 2D histogram of the raw TDC time spectrum per wire for the 1X1 plane 5. Produce a vector of histograms, indexed by the respective PMT number, for the HGC good pulse time versus the good pulse amplitude 6. Produce a scalar histogram for the HGC good pulse time versus the good pulse amplitude for all PMTs 7. Produce a 1D histogram of the good pulse integral for HGC PMT 3 8. Produce a 2D histogram of the good pulse integral versus PMT for the HGC with a cut that requires that the good pulse integral is > 0 28
