- Updates
- HCal
- coincidence trigger
- Bigbite Shower
- took cosmics
- took HV Scan during the night
- preshower has more hits on one side, maybe need to adjust HV
- need to check eve
- Hodoscope
- GRINCH
- taking LED run, seeing signal
- might need to turned down HV
- signal at VETROC is inverted logic - can fix with firmware setting - signal
- pulser rate to 100 Hz
- need to check with power switch - information on wiki - LED on port 8 - chech and halog with Brad
- will take LED data with cosmics - prescaled
- CDet
- issue with one PMT / bar, PMT works fine, might be because of electronics, will check with scope
- might need to open detector if not electronics
- GEM Bigbite
- took cosmics data : ADC distribution look ok at low level
- don't think need
- did not see many tracks but might be d
- GEM INFN clean room
- Helicity
- Beamline/scalers
- checked VtoF on Monday with 9 V battery, all look good
- NIM signals look ok
- negative offset on some channels
- LHRS value look odd in replay, most likely due to clock - counts in tree
- HV
- GEM floating HV, need CAEN HV crate - CNU has one crate with 6 slots - might need to to get more
- On-going tasks
- EPICS / start End of run logging script (Bob 99% ) - 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 ) - Provokar gave scripts for some variables to be added : HV for all detectors - issue with ET - Paul checking if there are scripts submitting event as Beginning Of Run event - might be reason for hang-ups see all events in data stream - might update insertion library
- 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 -
- sync check scripts other modules F1, 1190, FADC ( Andrew , Alex, Mark 20%) - Mark will work to have it available
- (90%) 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 )
- (new) Trigger latch TS to TDC ( Bob,Ole 100 % ) - trigger bank has latch
- event type decoding in analyzer - ( mention at analysis meeting ) - need to check with Ole - decoding done and will get in the tree - need to check with data -
- 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
- setup laptop for CH blujeans and Slack - need fix hard drive
- Possible new tasks
- Unresolved issue
- TI shower in William
- (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 ?
- (cannot be fixed - been that way forever) Raster X1 vs Raster X2 anticorrelation
- EPICS insertion : working better but still hangs for long runs
- 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
- HCAL fifo overflow https://logbooks.jlab.org/entry/3925327 - will check HCal people
- (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
GEn RP
- GEN RP DAQ
- both VTP working
- debugging fiber connection
- will bring VME crate
- new MPD might arrive for Thanksgiving
