09h35 Warmup ThomX

09h40 Cycling all magnets

09h50 Start Chillers

09h48 HV is ON

The reflected wave from the RF gun seems too high. Trying to set it to 27°C, but the clarinet temperature rises to 30.4°C and does not change.

10h15 HV is OFF

10h27 Stop the Gun  chiller.

10h50 Start the RF Gun chiller. The temperature is constantly rising.

11h25 Kevin reloaded the RF gun chiller. All is OK

 

 

 

17h00 Beam is in the ring. Receipt was loaded from 10/04/2025 17:32, RCDS, Good storage, Orbit adjustment to measure bunch length with MRSV. There is the light on the camera. Receipt saved 09102025 17:07

Emittance measurements during the shift as well, at  QP1, QP2 QP3 with low charge 70pC(0.8 mm) normal charge 100pC(1.3mm) and (300pC)3mm : here we wanted to see the affect of asymetric laser beam as well. 
QP4-Scan also but scan is strange (and long ... 1s expo to see something)
