Let's meet on Tuesday October 27 @ 11am in TED 2504 for a post-Run II discussion.
Agenda
- Run II and analysis tasks
- Rate v. Thickness: X-axis (compare w/ previous rates measurement, Lebow, FESEM), Y-axis (time and energy cuts)
- Asymmetry vs. Energy: X-axis (beam momentum results), Y-axis (time and energy cuts)
- Asymmetry vs. Thickness: X-axis (rate, Lebow, FESEM), Y-axis (time and energy cuts)
- Momentum vs. Gradient: X-axis (gradient), Y-axis (beam positions, DL, earth, steering)
- Emittance at MQJ0L02: measurements made for X/Y planes, on-line results look OK, but cuts to improve
- Energy spread: harp scans at 3 different pairs of quad measurements, should be consistent with same emittance/Twiss at MQJ0L02
- Discuss Charlie's writing assignments

- Please share your updates and material on the Box account
To Do
- (Joe) summarize process and results to measure beam energy
- (Joe) what photocathode did we use for Run I?
- (Daniel, Riad, Tim, Marcy) Corroborate the Lebow and FESEM measurements with foil rate measurements to assign X-axis and uncertainty for each foil
- (Tim) Explore and recommend heuristic fit approach for target thickness
- (Riad) Incorporate energy spread correction in data analysis
- (Daniel) Summarize Run II with cuts (T=+/- 2sigma, E=-1:3 sigma)
- (Daniel) Compute asymmetry is 0.5 sigma slices to explore dependence and determine appropriate energy cut
- (Marty, Tim, Riad, Joe) - Resolve approach for second scattering distribution
