08h20 ThomX was started: Modulator, frig, laser
08h27 Chillers were started, cycling all magnets
10h50 HV is 'ON'
12h38 RF Gun phase is 209 dg. Sect. phase is 207 dg. Charge from the RF gun is -70 pC. Laser Att. 260.
The strange behavior of the ICT signals does not allow for phase charge scanning.
Laser Att. Gun Charge pC
260 -70
270 -102
280 -157
290 -255
300 -320
310 -370
320 -400
400 -470
The receipt for MRSV --> for -440 pC Isol=240, adjasted phases (RF Gun 201 dg., Sect. 205 dg.). RF Cav. at 150 kV, Phase 16 dg., More or less good storage. ri-c1/BPM.03- Lib.03 TbTSum 1.8e8
-58 pC -->ri-c1/BPM.03- Lib.03 TbTSum 4e7
Scaling of the charge, very roughly:
In the injector, the charge measured by BPM after the e- gun 440 pC/58 pC ~7.6
In the ring, the TbTSum @2000turns 1.8e8/4e7 ~4.5
So, the difference is 1.6. This can be explained: beam losses in the ring during the injection, transport efficiency from the gun to the ring
