General
- Meeting time/day: Mondays at 11 am still ok?
December Run
- There was one opportunity for Compton running during December 2015 run
- Yves steered beam through chicane (at 11 GeV) pretty easily
- Did not see obvious collisions at first (background = 2000 Hz)
- Yves reduced backgrounds to 500 Hz
- Beam interrupted before we could do vertical scan
- See logbook for more:
Laser
- Laser became noisy right before beam test - was able to lock, sort of.
- Investigating source of noise:
- Seed laser ok Scope photo
- Coupling into fiber amp?
- Fiber amp itself?
- Back-reflection?
Photon Detector
Electron detector
- Status of detector in hall
- QWAD tests: JLab (Hoskins/Camsonne)
- QWAD tests: Manitoba
