08h41 Start Thomx: Modulator, Frigo, Laser

08h46 Start chillers, all magnets sycling

09h50 Start RF

10h55 Linac steerers are about from 22/01/2025: H [0.49 -2.94], V [-3.13 3.39] to align with QP1 - QP3

RF Gun phase is 164 dg., Sect. Att. is 2.64 dB, Sect. phase is 208 dg., Charges: -108 pC, -115 pC, -119 pC

if set QP5 through QP7 and all TL steerers 'Off' but TL/Str01-V1 (-1.6 A): TL/BPM02 X,Y 0,0; TL/BPM03 X,Y -6.0,+2.0, TL/BPM04 X,Y -6.0,+5.0

11h30 Beam is in the ring: TL/BPM02 X,Y 1.2,0.9; TL/BPM03 X,Y -4.6,+3.2, TL/BPM04 X,Y -2.7,+2.7

14h43 Good Receipt 50 MeV for X rays

14h55 FPC table scan: sigma y =140 um

15h16 FPC table scan: sigma y =124 um

16h25 X ray detector level 40000

16h57 RF 150 kV, X ray detector level 50000 (one point)

It seems that Ri-C1 STR06-V01 and  Ri-C2 STR02-V01 have wrong polarity

18h05 Breakdowns in the RF Gun, Vacuum interlock

18h10 Restored

18h20 Stop ThomX
