Trigger Commissioning plan

  • PS trigger with tagger (1 shift)
  1. Tune trigger parameters (timing offsets), prepare DAQ trigger configuration (no steady beam required)
(take calibration data with PS/tagger crates, 6 hours of steady beam)
  • FCAL and BCAL triggers (3 shifts)
  1. Perform threshold scans, tune timing offsets (steady beam required)
  2. Tune parameters for the FCAL & BCAL trigger
  • Commission ST/TOF triggers (1 shift)
  • Commission coincidence triggers for BCAL/FCAL and ST/TOF (2 shift)
- Trigger for FDC alignment
- Study FCAL coincidence with ST
  • Commission multiple triggers (3 shifts)
  1. Tune trigger delays and prescaling factors (steady beam required)
  2. Integrate PS, prepare trigger configuration files

FCAL/BCAL cosmic (threshold scans)

- FCAL cosmic
- FCAL cosmic
- BCAL cosmic
