• 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
