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!
