  • Updates
    • HCal
    • Hodoscope
    • GRINCH
    • CDet
    • GEM Bigbite
      • GEM working
    • GEM INFN clean room
    • Helicity
    • GEN RP
    • beamline
    • HV


  • On-going tasks
    • EPICS / start End of run logging script (fixed Bob 100% ) - just need to add configuration - will make a test configuration - need to make sure we have all variables - and variables to add at begining / end of run and during the run (EPICS 131 event - need to add to analyzer ) issue with ET - could try run ER and EB on same node - way to restart ET ?
      • Carl looking at issues still unresolved - ER and ET communication - code updated - might fix issues - could try to update emu and ET to test
    • (fixed database issue 100% working ) David readout scalers fine and are in tree - from LHRS - still need SBS side will check with Steve - ( done - looks good on sbs side )
    • script check MPD sync ( Ben , Andrew 20%) - code to unpack information already written - need run with those data - timestamp need some work - ( event count aligned, timestamp look odd maybe will check with Andrew )
    • sync check scripts other modules F1, 1190, FADC ( Andrew , Alex, Mark 20%) - Mark will work to have it available
    • reference channel to all crates - need HCal and Shower + RF - need to add RF to HCAL - 3 cables - in hodoscope crate - if shower FADC available can add

separate - need RC box for shower and hodo if possible - need to check - module will be added ( Mark )

    • Trigger latch TS to TDC ( Bob,Ole 100 % ) - trigger bank has latch
    • event type decoding in analyzer - ( done 100% ) - need update CH analyzer
      • Possible new tasks
        • User event inserted at each split with timestamp, spectrometer information - should discuss with
        • setup laptop for CH blujeans and Slack - need fix hard drive
    • filling up google sheet with run info


  • Unresolved issue
    • (need to test)FADC bad channel - FADC replaced but problem could not be reproduce - need to test more ( on going - low priority ) - FADC in test lab - DAQ setup - need to feed signal
    • (still there)warning PEB ROC - Bryan checking with Dave - might incorrect flag - not sure why - but data still in sync since only happens - still happening - not sure if it is an issue
    • HV can put documentation for other non EPICS control
    • (50%) near 100 MB/s limit for FADC crates - Shower window was divided by 2 - HCal windows - could do 150 ns - Move FADCs to top crate ? - can reach 5.2 KHz now
    • (cannot be fixed - been that way forever) Raster X1 vs Raster X2 anticorrelation
    • No clear signal in GRINCH - latency was adjusted - need check with beam ( see signal now )
  • 3820 scalers : issue to address - will get more as spare - and need -
  • 75 ns timing shift
  • ( new) DAQ running with APV and MPD in bad state


GEn RP

  • GEN RP DAQ


  • To do list
    • Must
      • timing diagram, diagnostic time shift
      • fix bad APVs
    • Like
      • VETROC HCAL
      • Shower FADC trigger
