- Updates
- HCal
- latency shift during the evening
- need to investigate
- coincidence trigger
- 60 ns window coincidence
- shift might have been seen during setting up EDTM
- veto for bigbite low with veto
- Bigbite Shower
- trying to take cosmics run with SBS field off : HV looks pretty good
- can use HV file for SBS Off run
- want to take another run with SBS on and same HV
- error message HV GUI : fixed by closing unused GUIs
- Hodoscope
- working ok
- still HV issues
- GRINCH
- CDet
- almost finished with last cosmic for efficiency analysis
- next week second half
- GEM Bigbite
- MPD with errors but run still starts - need to add more diagnostic - rebooting mpd fixed - Ben will change
- APV disabled - maybe
- GEM INFN clean room
- Helicity
- David and Paul working on analysis
- issue when writing two streams ? FADC and scalers information recorded - could think record
- RP detectors with GEn ?
- helicity decoder board - would give the seed for reported helicity for the trigger
- feedback ?
- could try take time setup PITA - beam charge asymmetries to check system, prompt and delayed
- Beamline/scalers
- David working on BCM/ unser analysis
- Charge script by Bob
- HV
- Rpi on remote switch
- send instruction to Steve on how to reboot RPis
- Steve will put a SBS EPICS page on wiki, want to add instructions
- hodoscope HV uses proprietary CAEN library ( radiation or too much traffic ) suggest to pull out unused cards to reduce traffic
- HCal
- On-going tasks
- EPICS / start End of run logging script (fixed Bob 100% ) - just need to add configuration - will make a test configuration - need to make sure we have all variables - and variables to add at begining / end of run and during the run (EPICS 131 event - need to add to analyzer ) issue with ET - could try run ER and EB on same node - way to restart ET ?
- Carl looking at issues still unresolved - ER and ET communication - code updated - might fix issues - could try to update emu and ET to test
- EPICS / start End of run logging script (fixed Bob 100% ) - just need to add configuration - will make a test configuration - need to make sure we have all variables - and variables to add at begining / end of run and during the run (EPICS 131 event - need to add to analyzer ) issue with ET - could try run ER and EB on same node - way to restart ET ?
- (fixed database issue 100% working ) David readout scalers fine and are in tree - from LHRS - still need SBS side will check with Steve - ( done - looks good on sbs side )
- script check MPD sync ( Ben , Andrew 20%) - code to unpack information already written - need run with those data - timestamp need some work - ( event count aligned, timestamp look odd maybe will check with Andrew )
- sync check scripts other modules F1, 1190, FADC ( Andrew , Alex, Mark 20%) - Mark will work to have it available
- reference channel to all crates - need HCal and Shower + RF - need to add RF to HCAL - 3 cables - in hodoscope crate - if shower FADC available can add
separate - need RC box for shower and hodo if possible - need to check - module will be added ( Mark )
- Trigger latch TS to TDC ( Bob,Ole 100 % ) - trigger bank has latch
- event type decoding in analyzer - ( done 100% ) - need update CH analyzer
- Possible new tasks
- User event inserted at each split with timestamp, spectrometer information - should discuss with
- autoanalysis at end of run - ( Paul has something setup 75 % but still need to be tested ) some issues launching jobs automatically - could have 3, one on each machine - not priority
- Possible new tasks
- still issues with non interactive shell - could try for next production
- setup laptop for CH blujeans and Slack - need fix hard drive
- filling up google sheet with run info
- Unresolved issue
- Scaler gating ( need cable and go through TTL/ECL converter ) (fixed)
- TI shower in William office (fixed)
- (need to test)FADC bad channel - FADC replaced but problem could not be reproduce - need to test more ( on going - low priority ) - FADC in test lab - DAQ setup - need to feed signal
- (still there)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
- HV can put documentation for other non EPICS control
- (50%) near 100 MB/s limit for FADC crates - Shower window was divided by 2 - HCal windows - could do 150 ns - Move FADCs to top crate ? - can reach 5.2 KHz now
- (cannot be fixed - been that way forever) Raster X1 vs Raster X2 anticorrelation
- (fixed ) EPICS insertion : working better but still hangs for long runs
- (other issues ) ROC19 busy fiber : issue became worse - MPD23 disabled - firmware fixes to be implemented for reset -
- (new) ER1 hangup - related to ET issue - VTP can get stuck - resetting run usually fixes
- (new) TDC errors - just one run though - https://logbooks.jlab.org/entry/3923168
- (new)HCAL flag file crashing ROCs : file too long ? - max file length to add -
- (fixed) Raster saturation ( fixed with 20 db attenuator ) -
- No clear signal in GRINCH - latency was adjusted - need check with beam ( see signal now )
- HCAL fifo overflow https://logbooks.jlab.org/entry/3925327 - will check HCal people ( maybe empty channels - trigger info )
- (new) issue with 50 k scripts making entry - logentry script puts a limit on java memory - 50 k and 5 k scripts were changed to use it - might want to use this new script to avoid issues - HALOG from Paul -
Logentry script: https://logbooks.jlab.org/entry/3933875 - is that a ulimit issue ?
- 3820 scalers : issue to address - will get more as spare - and need -
- tftp issue (fixed): network - switch transceiver
- (new) 75 ns timing shift
- ( new) DAQ running with APV and MPD in bad state
- disk filling up
- helicity with several streams
GEn RP
- GEN RP DAQ
- both VTP working : 10 gigE link from VTP to computer
- working on VTP update to handle more that 32 MPDs
- debugging fiber connection
- will bring VME crate
- new MPD might arrive for Thanksgiving : 15 MPDs
- new distribution box ready
- received lemo cables
- GEM layers can see clusters and cosmics
- still DAQ very unstable
- enpcamsonne cannot ssh out,
