  • Updates
    • HCal
      • issue between TI, one bad transceiver in one HCAL TI, replaced and working in stand alone
      • fixed prescales ( bug in readout list ) - now working
      • cosmics calibration on-going
      • combined run - replayed run - timing need to be adjusted for TI - can look at it today now TS is working
      • load slot error
      • Bryan managed to convert script in systemd, now threshold are restored when crate is power cycled ( running )
      • EDTM pulser work : mostly installed but need to be tested.
      • Ellen set up Raspberry pi , given the PVs , can look at the values and make a GUI, want to add as check to shift checklist
    • Bigbite Shower
      • taking data, Provokar focusing on calibration and optimizing HV
      • Mark changed TDC to available 1190 in hodo instead of F1
      • data looks ok for shower, preshower might need adjustement
    • Hodoscope
      • calibration using cosmics run, might need to tweak a few channel
      • calibrating NINO threshold : want to start with 1.6 V threshold
      • d
    • GRINCH
      • FADC in the crate and cabled
      • readout being worked
      • will look
      • need to find a better trigger with LED for more efficient data taking
      • NINO threshold set back to 1.5 V
    • CDet
    • LHRS
      • measured latency 1.08 us, will adjust and take data
      • will implement Fastbus
      • will plug L1A into scaler
      • prescale GUI for TS
      • start and end of run scripts, EPICS and scaler working
      • deadtime monitor, need L1A in scaler
      • will implement with full config
    • GEM Bigbite INFN
      • things are going well overall, just one chamber needing work
      • all modules took data and seems to work
      • working on enabling FIR
    • UVA clean room
      • almost finished cabling
      • waiting for VTP
    • GEn RP chamber
    • Helicity
      • waiting for opportunity to test the helicity in sbs account
      • will go on sbsvme29 eventually, can do basic testing on sbsvme29 until signals are fed there
    • Beamline/scalers
      • set up patch panel BNC to LEMO to go SBS DAQ
      • will work with Heidi start pulling cable
      • will use the L shape cable tray : slight modification
      • will start laying cables Friday afternoon
      • might need one more bundle
      • patch panel : will need to plug into helicity scaler
      • need to fan out BCM cable in DAQ bunker - add logic fan
      • need to copy helicty signal
  • On going tasks
    • Cable to weldment ( David / Heidi by mid week of Monday 27th )
    • cabling scaler/beamline crate ( David , Bob 50%)
    • HRS to TS and timing ( Bob, Maria 50% )
    • EPICS / start End of run logging script (Alex, Bob 50%) - need ER for insertion -
    • script check MPD sync ( Ben , Andrew ) - is new firmware ready ? check with Ben : code to unpack information already written - need run with those data - timestamp need some work
    • 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 ( Scott, Arun, Mark ? ) Just need to check it is working : look for 10 Hz EDTM - need to put in TDC too
    • Hodoscope v1190 clock ( Alex , Mark , Ralph) - still need to be checked - corrupted data when installed
      • check if calibration is needed after switch
    • Full configration all crates ( Alex, Bryan ) - can attach process to components - just finish CODA config
    • 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
    • BB CAL and HCAL at TS - delayed after coincidence (Mark, done ) - need the RC box for FADC ref channel - need delay single triggers - add GRINCH LED -
    • 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) - need read out configured - token passing and config file -
    • read threshold for discriminator from with RPi be Ellen, need give code to Steve - could add in logentry or wiki for adding in other scripts
    • scaler gating with TS (Alex) , need include code in readout list - Steve looking at adding to TS list
    • MPD crates on hareboot6 - can be power cycled remotely
    • put UVA GEM LV on reboot switch
  • Issues
    • transceiver issues
      • might need to replace
      • reset issue possible
      • 1 out of 4 HRS run with TS, if reboot TS usually fixes it
    • network issue : one short fiber replaced, will try to put in protective tube
    • LHRS TI : working now
    • GEM with TS hanging - real MPD out of sync - fixed with new firmware
    • Shower FADC bad channel - FADC replaced but problem could not be reproduce - need to test more
    • HCAL FADC bad channel - repaired by Bill - jumper wiggled loose - if no pedestal - could be this jumper
    • 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 - might be the data corruption from FAN IO - might be fixed now - also had
    • 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 - can send TI output ? will look at L1A TS output - might
    • Full config still hanging on LHRS and HCAL busy
    • GEM firmware - now GEM should be ok - buffering should - shower and GEM
  • use HV EPICS : type go_hv on aslow on adaqsc , need people to check if it works and if mapping is correct
    • control system studio try self update and NFS down
    • EPICS server need to be started at boot, Ole and Bryan
    • can put documentation for other control
  • Helicity board : 2 avalaible
  • F1 : need to test high rate
  • could increase threshold - window width 1000 ns maybe - need to be optimized - 40 ns - no remote threshold right now - on camac - might be able to control

288 channels = 18 NIM modules
