All (30) Your research projects, deadlines, papers, etc.
- (Max) Very different focal lengths of the gun field at CEBAF now vs. R30-3
  - Cathode-grid scan, orbit measured with BPMs: fake single-particle scan for comparison with simulation
  - CEBAF gun, measured Jan 18: trajectories (extrapolated), aggregated to RMS, focal length
  - CEBAF gun, GPT: trajectories, aggregated to RMS, focal length
  - R30-3 gun, GPT: trajectories, aggregated to RMS, focal length
  - cannot be extrapolated to high space charge
