1
Comparison of Fundamental and Dual Harmonic RF Buckets
V0 Volts (KV) δV0 Θ (deg) @ time = 0.3 ms ~ peak trapping loss Bucket Phase length: deg, Acceptance: eVs Time (ms)
2
Operational theta Oct & Nov 07
3
1&2RF Operational Gapvolts Oct & Nov 07
2RF - ~9kV peak (on 2 cavities) >200uA for last day or so of last run!
4
Longitudinal Profile at 0ms
green µA Red µA Blue dot 230 µA Black µA
5
Longitudinal Profile at 0.25ms
green µA Red µA Blue dot 230 µA Black µA
6
Longitudinal Profile at 0.5ms
green µA Red µA Blue dot 230 µA Black µA
7
Operational delta October & Nov 07
8
October 2RF Machine Physics
9
Tweaked delta during 50Hz operations
delta changed by changing (slowly) antiphasing -> phasing rise time
10
Achievable delta cf Theoretical
11
Analysis of pulse shapes
