  • Updates
    • HCal
      • 1 FADC fluctuating - Hall C FADC bad - brought to Bill to check
      • F1 RF : put in another chip with different configuration - smaller look back window, can send copy of trigger in same chip
      • 5 trigger output from SSP will go in TDC F1 - need to pull ribbon or twisted pair
      • V1190 in HCAL to be added -
      • PMTs already changed - will test more of noisy channels
    • ECal
      • cluster firmware for Ecal deployed - need to get the VTP readout working ( Alex, Ben )
      • SSP coincidence trigger done using dummy tables - will need to update with the final tables ( takes 1 hour to recompile the firmware )
    • GEMs
      • replaced module along with a couple of APVs
      • check of transceiver  : Ben gave a value threshold to determine if transceiver needs to be replaced
      • APV status : most APVs in, a few being replaced - should give 99.5 % of APVs, DAQ runs for a few hours but can get stuck - works fine with pulser : 2M events
      • check with Ellen for LV readback, might have available channels of ADC
      • Rafael ROI : made a GEM and APV info files processed, can take hit file and gives APV and MPD corresponding to the area and VTP crate
    • CDet
      • issue HV solved, a few cards replaced - spare channel - few channel on GUI which show current low to be checked
      • CODA stuck after 120 K events
      • Ed commited vfTDC decoder to Podd
      • need to make quick decoder to check
    • Beamline
      • updated the FADC firmware, need to test BPM readout
