  • Updates
    • HCal
      • new TI swapped
      • all fibers connected
      • Bryan will make the HCal config
      • TDC reference time working now
      • extra FADC with copy of trigger ( reference ) ( make sure the shaper is in and it is the good one ) , 10 supercluster analog sums - might need different latency for the reference time
      • need to check linear fan/in for offsets
      • need double check no capacitive coupling in wrong place
      • might need to add capacitor on some channels if needed
      • 10 ns cable extension to JLab PMTs - clusters line up better
      • can check with LED, but LED not yet ready
      • is there air flushing on PMT ? Not
    • Bigbite Shower
      • finished pulser test for shower and preshower

(look up table of ratios : some modules have isses in shower and still investigating preshower )

      • could not find any linear fan in/out - need check to Bogdan or Jack
      • might be modules in LHRS that might not be in used
      • connected cables from BB discrimator to HCAL DAC, threshold can be changed remotely
      • installing 2 FADCs in hodoscope crate for sum monitoring
      • one FADC channel was not working 1-4 - will remove FADC to be repaired
      • coincidence trigger : can work with Bob and Scott today - pulser ready
      • continue to debug and take cosmics overnight
      • need clean up area
      • all scalers plugged and to F1 - some features in TDC might be odd
      • need FADC trigger cables
    • Bigbite Hodoscope
      • noise issue figured out
      • could take data with DAQ and troubleshooting
      • 4 data runs at 4 different HV, of lower detector, next middle and upper third
      • still couple of channels to check
      • will try to add to full DAQ when not in use
    • GRINCH
      • setting up timing set up, using hodoscope trigger - signal was too long - shorten cabled - ADC gate working
      • everything reading out - some decoding issue - to look at the data
      • OSP submitted to work on upper half of detector - all ADC channels working
      • few TDC/ PMTs
    • LHRS
      • no major updates
      • waiting for cables
      • will try with TS
      • different modes : running mode with and with fastbus
      • Bryan tried run slave config
    • CDet
    • GEM BigBite
      • took cosmics data with UVA UV channels and taking data now with
      • INFN still has HV issues -
      • APV get zapped by HV - no way to disable a particular APV by software
      • module might be replaced or might replace whole layer
      • other module which might have bad cabling - can check when OSP approve
    • UVA GEM
      • taking cosmics
      • setup in EEL126 -
      • want to run optical - DAQ still being put back together - late next week at earliest
    • RF time
    • need add TDC
    • HV
      • CAEN HV used for INFN - non zero current from power supply - up to 200 nA - could be offset
      • HV cables to MPOD for spares

      • CAEN VME avalaible
    • Scalers
      • need cabling
      • need work on readout
      • one SIS set to 3801 for helicity in slot 16, rest 3800 - pulser can make fake helicity signal and LNE - can add a few BCM channels and add L1A to check synchronization
      • TI working now - can test read out - check on every event - reported helicity -
      • FADC for BPM/raster + helicity signal
      • minimum rate to make sure we don't miss some windows
    • Recoil polarimeter
    • EPICS
      • hacweb7 back on network, alarm handler scripts copied , sound installed - David will set it up with Steve
      • alarm handler gives a lot of error for some records
      • might be routing issue, might need to check with Brad Cumbia
      • some inconsistencies in EPICS gateway , need to make sure
    • BCM
      • linearity test on dnew and unew, David working with Dave - dnew 0.1% and unew 0.4% - scanning 1 uA to 170 uA
    • BPM
      • will look for Jason write up for twiddle testing
    • Helicity
      • issues getting readout to work properly with FADC
      • testing with TEDF crate, early next week
    • start / stop / EPICS script
      • working on tedbbdaq for test setup
      • will update scripts on ada
