    • HCal
      • All ADC and TDC working, all signals seems ok
      • adding new FADC for reference channel and supercluster
      • F1 TDC with reference time, still need to check to get it to work - hope to finish today
      • will take cosmics
      • pulser setup for coincidence trigger check next
    • Bigbite Shower
      • finished mapping checks : turning one column at a time, found a couple cables swapped, fixed, done

      • issue with summing module
      • one FADC not working
      • one fan in /out module not working
      • debugging
      • estimate few days to finish debugging

      • debugging a few empty TDC channels

      • Fiber to TI connected, need to get new firmware for the TI received this morning.

      • running cables from LHRS, BCM to SBS bunker, will add a new cable tray, see HALOG
      • new router installed, HRS DAQ working fine after
      • can use with one VXS crate with current firmware / library
    • CDet
      • reviewed all pixels on half module, will revised resistors of some of them

      • G0 scalers than can be used for detectors - need width at least 10 ns as input
      • FADC for BPM/raster + helicity signal
      • can add readout list
      • 3820 cannot get it to work so far, will take it out - and work on it in TEDF
    • Recoil polarimeter
    • EPICS
    • BCM
      • plugged signal in analog receiver for upstream - 30 uA - will check signal in counting house
