Update on UVa GEM layers for GEn-RP (Anu, John, Thir)

  • Working on the GEM database for tracking analysis on GEn-RP cosmic setup in EEL/125 which will eventually be extended to for Hall setup. Yesterday we had a productive meeting with Andrew where he helped us to get things started. Will continue to work with him continuously until we are able to use his scripts for tracking.
  • GEn-RP DAQ updates

Update on INFN GEM layers for GEn-RP (Ezekiel)

  • Resolving HV trouble on J1 top (seems due to shielding). APVs that are not well connected (id from cosmics) were repaired.
  • Plan to take a longer HV run for the whole layer this week.
  • Will need to repair a few APVs on J3.

Update on the Tracking efficiency / resolution (Andrew)
