* Layer 2 giving lower efficiency than naively expected. Nothing obvious in all detector performance plots. Likely due to some software thresholds added during pass change.
* plan for short luminosity scan, check BB layer 0 tweak and iterate with beam [https://sbs.jlab.org/DocDB/0003/000324/003/GEn%20GEM%20Luminosity%20Studies.pdf]

GMn GEM commissioning Meetings: WEDNESDAY 10:30am - 11:30am

Link to all previous meetings: GMn GEM Commissioning Meeting

Please use sbs_gems mailing list for plots/communications and HALOG entries relevant to GEMs!


Commissioning of the GEMs:

Update on BB GEMs

  • Layer 2 giving lower efficiency than naively expected. Nothing obvious in all detector performance plots. Likely due to some software thresholds added during pass change.
    • Will investigate further.

Update on layers for GEn-RP

  • Stand alone DAQ:
    • INFN LV?
    • need to keep running and monitor crashes
    • hv scan in parallel daq?
  • NDX probe installed in SBS electronics bunker

DAQ updates (Ben, Bryan, Alex)
