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

Problem with the camera was fixed

16h27 HV is 'ON', Charges: -424 pC, -420 pC, -461 pC

16h39 RF Gun phase set to 203 dg. sect. phase 203 dg. HV was off. Access to the bunker

16h50 HV is 'ON'.  Charges: -423 pC, -420 pC, -461 pC, ri-c1/BPM.03- Lib.03 TbTSum 2e8

17h04 HV was off. Access to the bunker

17h13 HV is 'ON'. 

17h24 HV was off. Access to the bunker

17h41 HV is 'ON'. 

17h52 ThomX was stopped

Goal: Beam Loss Monitors and Ring injection at high charge. Studies of the injector for high charge. Emittance measurements.

08h33 ThomX was started: modulator,frig, laser

08h40 Chilers were started, all magnets cycling

11h05 HV is 'ON'

11h15 RF Gun phase 194 dg. laser att. 280, Gun charge -100 pC.  Breakdowns in the RF gun

12h14 Breakdowns in the RF gun. Vacuum interlocks. Drop HV to 1210.

12h30 Restore HV

Increase of the charge from 100 pc to 450 pC. Tuning of the injector and ring injection. We suceeed to minilize the injection losses for the high chege. After our studies,  the charge in the ring incresed proportinally to the charge in the linac measured with the BPM.
