  • 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
  • move2silo works fine without NFS
  • dcrb replacement needed it one slot


2. TO DO

  • remove DMA from DiagGuiServer, check if it is related to ti dissapered for VME; check mutex again; 'free running' in future ?
  • trig1 reboot issue - Bryan
  • other smaller issues
  • epics in datastream
  • rcdb, including some useful scripts, add endofrun and duringtherun
  • ECAL and/or PCAL have to search to mips - in addition to main trigger
