  1. Trigger ACD/LAT Test Plan Eric Grove, Martin Kocian, Su Dong Trigger test plan

  2. Test Reorganization • ACD test STRs reorganized and are now all part of standard trigger tests. • Tests are classified into two categories: • Early ACD trigger tests with ACD+GASU alone (some with muon telescope) using LATTE 4, which can be performed in the tent. These are necessary to establish basic ACD trigger configuration as a base to facilitate development of LAT level tests later. • Full LAT trigger tests, include some ACD related tests. Tests will be modular for LICOS/FSW and LATTE 4 compatibility (in most cases). They are also designed to be usable as far as it could for the remaining journey of the LAT after shipped out of SLAC.

  3. Documentation Status • Full LAT test prelim plan http://www.slac.stanford.edu/exp/glast/trigger/admin/lat-trigger-test.txtrevised and first draft update incorporated into the perf & ops test plan doc by Eric. • The early ACD test descriptions are also created based on the original STRs: http://www.slac.stanford.edu/exp/glast/trigger/admin/acdtest-lat.txt to be incoporated into the perf & ops plan doc. • Summary of the test scripts will be documented in MD-07337 by Martin and prelim version is at: http://www.slac.stanford.edu/exp/glast/trigger/admin/trigger-test-scripts.pdf Trigger test plan

  4. Early Trigger ACD Tests • These are essential pre-requisite for establishing basic ACD settings for other trigger tests. • Can be performed with ACD+GASU (some with muon telescope) in the tent before LAT integration. • Scripts based on LATTE 4 • Need modern version of GASU with all ACD connectors and firmware include GEM arrival time. • Delay these tests until after full LAT integration could miss opportunities for finding potential problems early and significantly delay overall schedule.

  5. Early trigger ACD tests • ACD channel uniformity map • Charge injection tests: GEM veto list map, arrival time uniformity and ROI&CNO triggers. • ACD TREQ timing resolution • TREQ tests with muon telescope as reference for a few tiles. • ACD hit latching control parameter tuning • ACD hit delay & stretch effects and buffer boundary. • ACD standalone TACK scan. • ACD trigger rate for each tile. Trigger test plan

  6. Early ACD test preparation • Test scripts validated in the testbed lab.with MiniLAT by Martin. • Some worrisome effects observed on the MiniLAT which should be verified with full ACD asap. Trigger test plan

  7. LAT Level Tests • TREQ tests simultaneously for all towers/tiles and using ACD ROI trigger as timing reference. • TACK scan for TKR/CAL/ACD simultaneously using TKR triggers (need to see if sufficient for ACD). • Trigger efficiency tests (TRK/CAL/ACD triggers). • ACD veto test (CAL trigger, check TKR+ROI veto) • ACD trigger rate tests (ACD ROI trigger) • GEM self integrity tests (mainly data monitoring to check consistency) Trigger test plan
