- event type decoding in analyzer - ( mention at analysing )
- MPD retiming (?) with V1495
- 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 ? counting L1A between helicity event to track sync -done
- Full config still hanging on LHRS and HCAL busy : no hanging buffer level 2 - need more testing high rate
- transceiver issues : HCAL TI might be suspicious ROC 17 ( Scott replaced two transceiver but need to test might be bad connection )
- 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
- (new) deadtime ROC17 HCAL
- (new) deadtime ROC5 hodoscope
- Hall was cleaned - fibers left and table left
- 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
