From Hall A Wiki
- 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 ?
- HCal
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
- Beamline/scalers
- 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
