8h37 Warm-up ThomX: Modulator, Laser, Fridge
8h44 Chillers were started, cycling all magnets.
9h49 HV is ON
9h59 Can not see beam charge and cameras
10h37 Cameras are OK, ISTs are not.
10h38 Beam is in the ring at 50 MeV, all seems OK. Transition to 40 MeV
10h52 receipt from recipe_recipe_LI_TL_RI_all_20251209_17_54_51.txt
RF Gun phase 241 dg., Sect. phase 200 dg. Sect. Att. 3.82 dB, Linac steerers: H [0.87 -3.27], V [-3.0 3.63], Charges (BPMs): -111, -107, -107, -104, 98 pC
11h03 Beam is in the ring
Orbit correction. Optimization of the beam. The beam size at MRSV is about ~25 pixels.
The orbit is correction with a reasonable beam storage. (see the screenshot).
A short run wiht the X-rays thanks to Ronic.
The beam is very unstable. To minimize the syncrotron oscilations it is often neseccary to adjust RF cavity phase, sect. Att. value end section phase
14h15 HV on standby
16h18 HV is ON
