*Completed tasks
 
**Cable to weldment ( David / Heidi  100%? )
 
**cabling scaler/beamline crate ( David , Bob 100%)
 
**HRS to TS and timing ( Bob, Maria 50% ) - programmed high threshold for other detectors - dropped
 
**software for FADC pedestals : Bryan will give to Brad ( done )
 
**Prescale GUI (Bob 100%) - up to 8 TS input
 
**RF (Bob ,Maria 100%) - located RF prescaler and signal - need to send to HRS and SBS weldment - in hodoscope TDC - looking for new RF board - looked ok on scope but seems odd on data - sometimes can vary ( 180 to 160 ns might be 1190) - will send to HCal F1 - might feed a clock in another channel - LHRS 103.7 KHz clock - can send copy from HRS -
 
**EDTM at least 1 Hz for helicity ( Scott, Arun, Mark ? 100 % ) Just need to check it is working : in 1190  -  GUI working
 
-running at 20 Hz - keep 0.5 A 5V fuse on hand - Right now disabled - can turn on - EDTM is 20 Hz 
 
**Hodoscope v1190 clock ( Alex , Mark , Ralph) - done
 
***check if calibration is needed after switch (Rachel,Mark 100% )- to do but should not be much - check with Ben if he as software - Calibration done with RF time - ~93 ps per channel - RF prescaler seems OK -
 
**Full configration all crates ( Bryan - 100% ) - can attach process to components - just finish CODA config - need add sbsvme29
 
**need setup screens for online display and analysis, Hall A tools on big screen - can make a map file - (Bryan , done ) - change browser home page to GMn to experiment -
 
**data rate test with new computer and 2 VTPs ( Alex, Bryan 20%) - sbsvtp1 booted and online - could reduce dead time and setting - TOP J2 fiber could - could set a MPD -
 
***could set that a separate 
 
**test GEM zero supression ( Sean, Holly )- done
 
**FIR ( Sean , Ben , 20 % ? ) Not working - Ben will test in DAQ Lab - long HDMI cable - can get from GEN RP - follow up Paolo and Evaristo
 
**(done) GEM cosmics ( Sean, Holly ) 70 % - still working on gas issue - no HV plateau curves for INFN chambers
 
**(done)Shower cosmics (Arun, Provokar ) 100 %
 
**(done) HCAL cosmics (Scott) - investigating the issue - most channel working - most likely light guide - have enough overhead on HV to run this way
 
**optimize trigger rules
 
**GRINCH cosmics ( Bradley ) - need 3 more runs x 8  - 4 FADC - only 64 out of 550 - if need moving around but will look at where they are for now.
 
**Hodoscope cosmics ( Ralph ) - calibration TDC and nino thresholds : looks pretty good - just need to look at FADC - upper third, 2 left  - 100% have all ADC -
 
**DAQ documentation ( Alex, Rachel ,Don) ( 99 % resets, need starting CODA 100 % / troubleshoooting 80% ) - found some issues being addressed
 
**suggest taking all detectors cosmics every night
 
**add scaler crate to full config ( Alex, Steve, Paul - 100 %) - working
 
**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) -
 
**add FADCs for shower sum and HODO ( David / Mark /Bryan : done )
 
**add FADCs for GRINCH (Bryan/Alex) - done - mode 7 or mode 1 ?
 
**read threshold for discriminator from with RPi be Ellen (done) (noise issue was fixed), need give code to Steve ( done )  - could add in logentry or wiki for adding in other scripts ( check with Steve ) - Scott wanted to add those readback in GUI - decide to add the data stream
 
**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

*Fixed issues
 
**(fixed)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 - (fixed after firmware downgrade )
 
**(fixed)network issue : one short fiber replaced, will try to put in protective tube (fixed)
 
**(fixed )LHRS TI : working now ( no issues seen so far )
 
**(fixed)GEM with TS hanging - real MPD out of sync - fixed with new firmware - (fixed : 5.2 KHz bufferlevel 5)
 
**(need to test)Shower 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
 
**(fixed)HCAL FADC bad channel - repaired by Bill - jumper wiggled loose - if no pedestal - could be this jumper (fixed)
 
**(fixed)HCAL ROC16 fiber - will double check if fiber 5 enabled - use slave5 - added additionnal fiber for ROC16 - (fixed) by cleaning
 
**(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
 
**(fixed giving up F1)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 (fixed) -
 
**(fixed)Helicity scaler readout : issues working with same DMA configuration - scalers doing regular VME (fixed)
 
**(done)need copy of L1A for helicity scaler - can send TI output ?  counting L1A between helicity event to track sync -done
 
**(fixed) Full config still hanging on LHRS and HCAL busy : no hanging buffer level 2 - need more testing high rate - (fixed after firmware downgrade)
 
**use HV EPICS : type go_hv on aslow on adaqsc , need people to check if it works and if mapping is correct - bug with off button - hodoscope channel turning off
 
***control system studio try self update and NFS down
 
***EPICS server need to be started at boot, Ole and Bryan - ? ( rebooted crate , working now ? )
 
**can put documentation for other control
 
**(still ongoing) ROC17 F1 data - data left at sync event - seems fixed after fixing busy cabling - still see a few with high random rate ( tweak trigger rule and gate width ? Is it an issue ? ) - put F1 trigger input / output on scaler
 
https://logbooks.jlab.org/entry/3924554
 
 
**(fixed) hodoscope no data in some events - seems fixed after putting busy from distribution board
 
**(fixed) HCAL ROC17 crash / shutdown ( fixed after replacing CPU )
 
**(fixed) V1190 stuck at prestart - went away after switch to external clock - maybe bad connection ( Bryan took out readback loop - not hang - maybe check parameters are correct)
 
**(fixed) deadtime ROC17 HCAL ( bad CPU connected at 100 Mbps - maybe fixed need test)
 
**(fixed) deadtime ROC5 hodoscope ( need to test - issue with busy fixed )
 
**(fixed - only combined DAQ) CODA database corruption - make sure to release components when run is stopped
 
**(fixed but not understood) one night with bad latency ( was an ECL cable inverted somewhere ) GEM estimated about -200 ns shift + 140 ns today
 
**(new, sort of) HV hodoscope channels turning off
 
**(fixed) Glasgow colleague IP maybe black listed -
 
**(work around) if you try to edit wiki from frame of GMn website, it does not work, need to open the wiki in a new browser window to log into wiki
 
**(fixed) sbsvme29 TI error with GMN1 config
 
**(cannot be fixed - been that way forever) Raster X1 vs Raster X2 anticorrelation
 
**(new) EPICS insertion
 
**(new) ROC19 busy fiber
 
***not clear what is happening - still to be investigated - TD see busy - need to make sure shift worker keep an eye - maybe alarm
 
**(new) DC1 hangup
 
**n(new) TDC errors - just one run though - https://logbooks.jlab.org/entry/3923168
 
**(new) sbsvtp1 not detecting MPD fiber

  • 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
    • 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%)
    • (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

    • (new) Trigger latch TS to TDC ( Alex,Mark 0%) try F1 ? or add vetroc gem crate - or hodoscope ) - trigger bank has latch
    • event type decoding in analyzer - ( mention at analysis meeting ) - need to check with Ole ?
    • MPD retiming with V1495 ( done ) - timestamp issue still need to be implemented - in datastream but might still have issues - can fix with firwmare update - can use TI timestamp to check with other - MPD timestamp not always reliable and misaligned at the start - might be best to test in EEL first - timestamp - event counter working - couple of hours - updating MPD, V1495 and readout list - might need 4 hours - can induce change in latency -
    • need to look at MPD timestamp make sure they all agree
      • Possible new tasks
        • rcdb
        • check latency with DiagGui ( needs firmware and code work - low priority )
        • User event inserted at each split with timestamp, spectrometer information - should discuss with andre
