  • Hodoscope
  • GRINCH

• • CDet
  • LHRS
  • GEM Bigbite INFN
  • UVA clean room
  • GEn RP chamber
  • Helicity
  • Beamline/scalers

• On going tasks
  • Cable to weldment ( David / Heidi 70%? )
  • 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 ) - code to unpack information already written - need run with those data - timestamp need some work
  • RF (Bob ,Maria ) - located RF prescaler and signal - need to send to HRS and SBS weldment - need add F1 for RF
  • sync check scripts ( Andrew , Alex 0%)
  • 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) - done
    • check if calibration is needed after switch - to do but should not be much
  • 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 - (Bryan , done )
  • 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 ) 80 % ?
  • HCAL cosmics (Scott)
  • GRINCH cosmics ( Bradley )
  • Hodoscope cosmics ( Ralph )
  • DAQ documentation ( Alex, Rachel ,Don) ( 10 % resets, need starting CODA / troubleshoooting )
  • 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 (Mark , done 15 ns ) - add GRINCH LED (done #5) -
  • reference channel to all crates - need HCal and Shower + RF
  • add FADCs for shower sum and HODO ( David / Mark /Bryan : done )
  • add FADCs for GRINCH (Bryan/Alex) - done
  • read threshold for discriminator from with RPi be Ellen (done), need give code to Steve - could add in logentry or wiki for adding in other scripts
  • scaler gating with TS (Alex, Steve) done ? , need include code in readout list - Steve looking at adding to TS list (done)
  • MPD crates on hareboot6 (done) - can be power cycled remotely
  • put UVA GEM LV on reboot switch (done)
  • (new) Trigger latch TS to TDC ( try F1 ? or add vetroc gem crate )
  • event type decoding in analyzer

• Issues
  • transceiver issues : HCAL TI might be suspicious ROC 17 ( Scott replaced two transceiver but need to test might be bad connection )
    • 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 - (fixed : 5.2 KHz bufferlevel 5)
  • Shower FADC bad channel - FADC replaced but problem could not be reproduce - need to test more ( on going - low priority )
  • HCAL FADC bad channel - repaired by Bill - jumper wiggled loose - if no pedestal - could be this jumper (fixed)
  • HCAL ROC16 fiber - will double check if fiber 5 enabled - use slave5 - added additionnal fiber for ROC16 - fixed by cleaning
  • warning PEB ROC - Bryan checking with Dave - might incorrect flag - not sure why - but data still in sync since only happens - still happening - not sure if it is an issue
  • 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 ? done
  • Full config still hanging on LHRS and HCAL busy : no hanging buffer level 2 - need more testing high rate
• 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
  • (new) ROC17 F1 data - data left at sync event - seems fixed after fixing busy cabling
  • (new) hodoscope no data in some events - seems fixed after putting busy from distribution board
  • (new) HCAL ROC17 crash / shutdown
  • (new) V1190 stuck at prestart - went away after switch to external clock - maybe bad connection
  • (new) setup network port for UVA chamber testing in EEL 125

• 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
