  • Updates
    • HCAL
      • cable GUI installed on enpcamsonne, section 7.5 on wiki for documentation
      • looking at cable length attenuation


      • gathering spool of cables and lemos to give to Wendy for 60 more cables for overlapping summing
      • Chris agreed to make a patch panel for the DAC
      • looking for the FADC being repaired
      • maybe look into setting up external clock for F1
    • Bigbite shower
      • Issue with Fastbus getting stuck in weird state. Bryan has a temporary fix.
      • 12 FADCs added, jumpers checked to be set to 2V and will start cabling
      • Provokar more data for preshower calibration and will switch to FADC
      • noise on one side of preshower, HV crate was replaced ( goes away when moving to other HV crate ) but still shifting pedestals on some channels, still need to look at signals with scope ( usually 5 mins runs ), might be ground loop - HV supposed to have same ground but need to check. Some channels have the shift on some channels with scope directly on PMT ( grounding near PMT did not help ), but disappear R26 when HV swapped to another HV card.

Schematics of bases of PMTs ? From Hermes not sure we have. Look with scope on HV too, see in Fastbus even with filter ( so higher frequency noise ).

    • Bigbite hodoscope
      • fix issues with analysis script - everything working
      • more data taking
      • Steve working on the TDC scaler using the hodoscope DAQ
