  • Updates
    • Rate tests
    • HCAL
      • Progress new HV - was using amplitude - will use integral instead
      • will start calibrating HV
      • cosmics paddle setup on top, second paddle - under HCAL - will try to have cosmics trigger for calibration - can also get timing resolution
      • will work on coincidence
    • Bigbite Shower
      • replaced module - signal consistent
      • most FAN IN/OUT found in bad shape - only 3 good ones
      • need FADCs for sums - will check with Chris
      • FADC slot 6 replaced - broken given to Bill Gunning - tested but did not see - channel 7 of FADC
      • Additionnal SD board for FADC from ED
      • issues with F1 TDC at high rate, DMA errors, TI output about 20 ns, will switch to OT#2 so we can try larger gate
      • Bryan check with Ed, width should be fine
      • trigger from TDC output might be double pulsing - will switch to OT#2 - and put in scaler
      • coincidence trigger BBCal and HCal -
    • BigBite Hodoscope
      • Good date at 4 different HV setting - need upper third
      • pedestal fitting and can tune HV
      • trigger on other detector for timing calibration
      • need to use fast trigger , Ralph will check with Mark
    • GRINCH
      • OSP to access detector : 2 NINO cards replaced - fixed all empty channels mostly loose cables - 1 dead PMT - both ADC and TDC working
      • trigger setup last night
      • cosmics data - all ADCs cables - top 16 channel still weak - replaced with a spare
      • setup ADC cables on front-end and long cosmics run
    • CDet
      • power outage test lab
      • working on quality check on data
    • Bigbite INFN GEM
      • trying to fix noise issue - applying shielding to one INFN module - will take data to see if it is better - done on detector
    • Bigbite UVA GEM
      • running smoothly - data look normal - discrepancy between offline and online common mode
      • XY and UV taking
    • Scalers
      • testing scalers on sbsvme29 SIS3800 and G0 scalers up to slot 10 - some not working -

Discriminator scaler working but mapping wrong -

    • Beamline
      • last check on BCM and VtoF, cleaning the fan out module, will do current test of unser
      • still need to run cables -cable from green wall to SBS weldment - 25 cables
    • LHRS
      • 4 cables from LHRS to weldement
      • connection to LHRS and TS
    • HV
    • RF
      • plug in FADC ?
      • can add F1 TDC -
    • Helicity
      • changes to be put in
    • EDTM study ( Bob can help )
    • Reference channel
  • On going tasks
    • Cable to weldment ( Jack ? )
    • cabling scaler/beamline crate ( David , Bob 0%)
    • HRS to TS and timing ( Bob, Maria 0% )
    • EPICS / start End of run logging script (Alex, Bob 0% 09/15 )
    • script check MPD sync ( Ben , Andrew )
    • RF (Alex, Bob )
    • sync check scripts ( Andrew , Alex )
    • Hodoscope v1190 clock ( Alex , Mark , Ralph)
      • check if calibration is needed after switch
    • Full configration all crates ( Alex, Bryan )
    • 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
    • EDTM
    • BB CAL and HCAL at TS - delayed after coincidence
  • Issues
    • Shower FADC bad channel - FADC replaced but problem could not be reproduce - need to test more
    • HCAL ROC16 fiber - will double check if fiber 5 enabled - use slave5
    • 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
  • Status software in a-onl@aonl1
  • GRINCH
    • still need to install - need to check if commits were merged
    • still running locally -
  • Shower
    • installed
    • one script working with TS files
  • GEM
    • Andrew tried already
  • Hodoscope
    • installed
  • HCAL
    • setup and can look at data


  • All crates
  • Bigbite config : GEM GRINCH Hodoscope
  • need add HCAL and HRS
