08h45 Start-up modulator, laser, magnets

09h38 Shutter Laser Linac is yellow. Tuning off the gun operation key does not change it to the red. Need help.

09h55 HV is on

09h56 HV is off. The fridge was started then chillers.

10h20 The laser shutter is OK.  HV is on

Linac steerers were adjusted.

11h35 Energy = 50 MeV, Laser Phase 9 dg., Sect. Phase 223 dg., Sect. Att. 2.19 dB, I_Gun -48.3388 pC, I_Linac -54.8343 pC, I_TL -53.5573 pC RF_Ampl. 0 kV, RF_Phase -30.5 dg.

Beam is in the ring W/O RF

11h45 RF is on

11h54 Energy = 50 MeV, Laser Phase 9 dg., Sect. Phase 223 dg., Sect. Att. 2.12 dB, I_Gun -49.1448 pC, I_Linac -55.6953 pC, I_TL -54.5153 pC RF_Ampl. 49.3668 kV, RF_Phase 35.5 dg.
It looks like RF cavity tuning does not work. Help is needed.
