20 Trigger Wide range of fundamental issues in cosmic ray physics Trigger must be able to select: Event density Hit multiplicity

21 Trigger 50 ns 00 ns

22 Low Multiplicity Low Multiplicity sections (65 LS each) 6 LOWM boards ΣLOW (sum of LOWM) TLOW (total sum of lowm) Fast Trigger CLUSTER each module => 3 SUPERCLUSTERs for Fast Trigger

23 High Multiplicity High Multiplicity sections (65 LS each) HIGHM boards in parallel (7,6,3,6) THIGH(total sum of HIGHM)

24 Trigger 3 different trigger logics based on LM and HM from LS. Hardware is implemented as synchronous pipelines with a common clock at 33 MHz ) Low Multiplicity Trigger when programmed threshold of fired PADs is exceeded on the entire carpet ) Density Trigger (Fast trigger) CLUSTERs make a SUPERCLUSTER. It triggers when exceeded a programmable threshold (in the LM scheme) 3) High Multiplicity Trigger when a programmable number of CLUSTERs with a specific multiplicity (7,6,3,6) is exceeded All trigger are handled by a TRBOX which can mask or combine them (And and OR) to define topological triggers

26 Conclusions The Local Station and the trigger system are working successfully in Yangbajing. Some upgrade are planned to read analogic big pads
