  • Updates
    • HCal
    • Bigbite Shower
    • Hodoscope
    • CDet
    • LHRS
    • GEM Bigbite INFN
    • GEM Bigbite UVA
    • GEn RP chamber
    • Helicity
    • Beamline/scalers


  • On going tasks
    • Cable to weldment ( Jack ? )
    • cabling scaler/beamline crate ( David , Bob 50%)
    • HRS to TS and timing ( Bob, Maria 0% )
    • EPICS / start End of run logging script (Alex, Bob) - need ER for insertion -
    • script check MPD sync ( Ben , Andrew ) - is new firmware ready ? check with Ben
    • RF (Alex, Bob ) - located RF prescaler and signal - need to send to HRS and SBS weldment - need add F1 for RF - can put in FADC avalaible ? -
    • sync check scripts ( Andrew , Alex )
    • EDTM at least 1 Hz for helicity
    • Hodoscope v1190 clock ( Alex , Mark , Ralph)
      • check if calibration is needed after switch
    • Full configration all crates ( Alex, Bryan ) - can attach process to components
    • need setup screens for online display and analysis, Hall A tools on big screen - can make a map file
    • data rate test with new computer and 3 VTPs ( Alex, Bryan ) -
    • test GEM zero supression ( Sean, Holly )- done
    • GEM cosmics ( Sean, Holly )
    • Shower cosmics (Arun, Provokar )
    • HCAL cosmics (Scott)
    • GRINCH cosmics ( Bradley )
    • Hodoscope cosmics ( Ralph )
    • DAQ documentation ( Alex, Rachel ,Don)
    • suggest taking all detectors cosmics every night - took a few runs !
    • add scaler crate to full config ( Alex, Steve )
    • coincidence trigger (done ? ) - need fine tune inputs at TS
    • EDTM- starting will work on it this afternoon
    • BB CAL and HCAL at TS - delayed after coincidence (Mark, done )
    • reference channel to all crates - need HCal and Shower + RF
    • Final CODA config (Bryan, Alex)
    • add FADCs for shower sum and HODO ( Mark, David ?)
    • add FADCs for GRINCH (Bryan/Alex)
    • read threshold for discriminator from with RPi be Ellen, need give code to Steve
    • scaler gating with TS (Alex)


  • Issues
    • network issue : one short fiber replaced, will try to put in protective tube
    • LHRS TI : working now
    • GEM with TS hanging - need to check
    • Shower FADC bad channel - FADC replaced but problem could not be reproduce - need to test more
    • HCAL FADC bad channel
    • HCAL ROC16 fiber - will double check if fiber 5 enabled - use slave5 - added additionnal fiber for ROC16 -
    • warning PEB ROC - Bryan checking with Dave - might incorrect flag - not sure why - but data still in sync since only happens
    • Shower F1 issue at high rate - need to check with OT#2 - check at sync event implemented - DMA error might come from multiple pulsing - switched to 1190
    • Helicity scaler readout : issues working with same DMA configuration - scalers doing regular VME
    • need copy of L1A for helicity scaler
    • Full config still hanging on LHRS and HCAL busy
    • GEM firmware
  • use HV EPICS : type go_hv on aslow on adaqsc , need people to check if it works and if mapping is correct
