08h30  Warm-up ThomX: Modulator, Laser, Fridge

08h36 Chillers were started, cycling all magnets

09h33 HV is ON 

09h34 HV set to 1215 V RF Gun phase is 188 dg.

11h09 Help needed! Something is wrong with the TL bends.

11h44 Something is wrong with the section attenuator. Reducing the attenuation results in a decrease in the section's output power.

12h15 OK, finally we got  it. RF Gun phase 182 dg. Sect. phase 298 dg. Sect. Att. 0.59 dB, 50 MeV, Li/HFI/ATT.01-MOT.01 ==> 311 steps Sect. Output -0.123 V

Sect. Output -0.123 V Mot. pos. 1699 steps but Sect phase = 211 dg. Calc/Li/HFI/ATT.01-MOT.01 is not working properly.

12h31 Beam is in the ring W/O RF

12h35 RF 100 kV
