Agenda

Meeting room=F227 in Cebaf Center

General

  • Run extended to December 22
  • Will definitely run over Thanksgiving
  • Compton was tuned up last Tuesday (4 pass) - backgrounds awesome right off the bat.
  • Switch to 5 pass might start next week (Wed., 11/9)

Laser

  • Laser locking pretty reliably.
    • Like last run, need to keep changing PPLN temperature to maintain power.
  • Measured cavity decay time [1]. Fast enough for afterglow tests?

Photon Detector

  • Backgrounds - performance with JAWS vs. 10 mm collimator from last spring
  • Asymmetries (Accum0, etc.)
  • Afterglow test plans (use laser?)
  • Counting mode DAQ update

Electron detector

  • Detector in Hall
    • "Photon stopper" stuck open. Can't close for any edet beam test.
  • "Summary" of Edet Workshop
    • Near term plans
    • Longer term plans
