  • we discussed DAQ/Trigger system problems observed during engineering run in December 2017. Some notes can be found in ERROR Book (records dated Dec 2017).
  • holdoff time was 14us for rule 1 and few times higher for other rules; when decreased, problems appeared reading one of CAEN TDC boards, reading VTPs, and probably(not confirmed) reading FADCs, have to be tested
  • when holdoff-related problems resolved, high event rate test to be conducted (random pulser 60kHz)
  • trigger components fixed after the run: HTCC clustering, FTOF - will be tested
  • trigger components to be finished: DC, geom match, FT-HODO coincidence
