  • Updates
    • HCal
      • started doing calibration
      • fixed flag files
      • can talk to the LED now, but errors in replay, might be missing a header
      • prescales not prescaling
      • one FADC needed to be fixed
      • script to reset DAC at boot, need to test
      • adjust timing
      • high rate
    • Bigbite Shower
      • finished attaching all capacitive coupling
      • finished replacing bad modules : looks better than before
      • calibration
      • documentation
      • coincidence time : Mark, Scott and Arun figured out time difference between HCAL and Bigbite
      • 2 FADC from Brad
      • F1 data looks good now and no crash : using OT2 helps
      • start setting rol for FADCs on bbhodo
      • delay single triggers : can line up L1A with TS delay ( Bryan will look into )
      • reduce window of BBShower FADC from 200 to 100 ns
    • Hodoscope
      • still calibrating HV - have all files for data scan - fit pedestals and fitting ADC signal - writing script to compute HV
      • Mark will test FADC rol this afternoon
    • GRINCH
      • decoding data - ROC ID set 526 - was set to 4 - issue was fixed - can look at data
      • need to adjust latency with TS
      • taking data for gain calibration
      • will install FADC
    • CDet
      • restarted system, everything is ok besides HV, will work on that and start taking data. All rest working
      • Hanjie helping
    • LHRS
      • read out with TS
      • FADC working
      • Bob will check TS config more today
      • check scalers
      • need to add helicity scaler
      • after Fastbus + 8 FADC
      • 4 cables from LHRS : need to check where HRS trigger is arriving, and other
    • GEM Bigbite INFN
    • GEM Bigbite UVA
    • GEn RP chamber
    • Helicity
      • finished helicity readout , took data and check if look ok
      • check everything compiles with full readout with the library
      • new helicity decoding board is avalaible : just one avalaible - need to go in VXS crate - could go in LHRS - could that go in TS crate ?

can take front panel -

    • Beamline/scalers
      • sbsvme29 : scalers working
      • still need cabling
      • need plug triggers and L1A
      • need to add to full config
      • spot++ still need to run on current setup
  • 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 0% 09/15 ) - 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 )
    • suggest taking all detectors cosmics every night
    • add scaler crate to full config
    • 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
    • reference channel to all crates - need HCal and Shower + RF
    • Final CODA config
    • add FADCs for shower sum
    • add FADCs for GRINCH and HODO
    • timing hodoscope - V792 gate
    • read threshold for discriminator from with RPi be Ellen, need give code to Steve
  • 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 -
    • Shower F1 issue at high rate - need to check with OT#2 - check at sync event implemented - DMA error might come from multiple pulsing - might
      • Helicity scaler readout : issues working with same DMA configuration - scalers doing regular VME
      • need copy of L1A for helicity scaler


  • use HV EPICS : type go_hv on aslow on adaqsc , need people to check if it works and if mapping is correct
