January 3, 2018 online meeting minutes

present: Sergey Boyarinov, William Gu, Ben Raydo, Nathan, Stepan

• 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
