*Updates
**HCal
***timing resolution ? Still need to check RF time
**coincidence trigger
**Bigbite Shower
***could not see signal in Shower 17-3 - from last night cosmics
***Preshower gain matching changed after magnet test 
**Hodoscope
***working on calibration : offset and timewalk done
***500 k events - will redo with more statistics
***timing resolution from 250 ps to 150 ps
***working on HV gain curves
***looking at FADC from cosmics : looks ok
**GRINCH
***
**CDet
***still working on the PMT10 with missing pixels - the paddles might not be separated - might treat them as one single channel
**GEM Bigbite
***everything looks good
***waiting for swap to UV GEM, UV GEM was tested
**GEM INFN clean room
**Helicity 
**Beamline/scalers
***no major updates
***still looking at LHRS scalers rate - working with other code and working on handling overflow
***gating of scalers : Steve working on it
***still ET insertion failing after two splits
***scalers inserted in event based
***user events not working at end
**HV

*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 )  issue with ET  - could try run ER and EB on same node -
**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 
**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 - ( mention at analysis meeting ) - 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
- still issues with non interactive shell - could try for next production
****setup laptop for CH blujeans and Slack - need fix hard drive



*Unresolved issue
**Scaler gating ( need cable and go through TTL/ECL converter )
**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
** 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 - need check with beam
**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 : VTP and

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
