keyword=Arc Energy Measurement - Aug 2, 99These are the results of the Arc Energy measurements for Aug 2, 1999
We first made measurements with 5 uA cw, Achromatic beam tune
BdL measurement (Achromatic mode): Run #434: I = 6623.32 T.mm
Harp Scan (#1,2,3,4): Run #196 (shown on plot 1 below)
We then went to Dispersive mode tune. 5 uA cw
Harp scan # 197: Theta = 34.2964 degrees (shown in plot 2 below)
Harp scan # 199: Theta = 34.2968 degrees
BdL measurement (Dispersive mode): Run #435: I = 6623.39 T.mm
BdL measurement (Dispersive mode): Run #436: I = 6623.38 T.mm
Average BdL = 6623.385 T.mm
Average angle = 34.2966 degrees = 0.598589 r
The Energy = 3317.2 MeV +/- 0.5 MeV
Comments:
1. The Fast Feedback was on during this process and this is reflected in the compact beam envelopes with practically no jitter.
