Agenda

Meeting room = Cebaf Center F227

General

  • Still need survey report for laser table --> update BPM offsets

Electron detector

  • Detector status
    • work on noise with Jinlong, maybe one bad board was causing problem, a few hot strips but most rates disappear with high threshold
    • added additionnal network switch
    • added network scope of analog signal
    • web cam for detector motion and dark current readout
    • not sure if we can fix the hot strips easily, needs to decable both side at the same time
    • to do
      • test FSD with magnets on
      • shielding scope / switch
      • From Dave estimates at 2.2 GeV : Compton Edet 14.8 mm, zero crossing 7.6 mm ( I think we can go as close as 5 mm from beam, so expect about 40 strips for Compton signal
  • QWAD adapter boards
  • Counting DAQ

Laser

  • Cavity status
  • DOCP in cavity

Photon Detector

  • CREX preparations

Analysis

  • Too busy for analysis!
