Near term work plan

  • see the GEM commissioning run plan for GEn-II here: [1]


  • Thoughts on special run requests during GEn:
    • Luminosity studies (Nilanga)
    • Full readout studies for negative pulse studies and etc (Sean)
    • HV efficiency scans with beam

Update on BB GEMs

  • Cosmic data taken this week and GEMs remain stable.
  • Ben investigating 3 ADC difference in CM calculation in the firmware.
  • Cleaning up online monitoring for GEn

Update on INFN GEM layers for GEn-RP

  • Issue with APVs in SBS setup. Running disabled at the moment to stabilize DAQ.

Update on UVa GEM layers for GEn-RP

John:

  • All layers/modules of SBS stack are operational and taking data.
  • Further latency adjustments improved hits and efficiencies
  • Documentation update
  • CAEN HV Module paper work
  • Need to get an update on SBS gas system
  • Repositioning the scintillators

Update monitoring with new GEMs in GEn-RP

  • Online monitoring and SBS-offline preparation for GEn-II

DAQ updates (Ben, Bryan, Alex)

  • SBS DAQ integration to GEn-II
