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
