Hello,
I short-circuit the MPS input to modulator, we can trig modulator, the klystron filmant time goes to full time , need 45 min, you can start at 14:35 |
|
IC, VM; Restart of the accelerator
|
08h35 Start-up modulator (it was already on standby), laser, magnets, cycling.
As yesterday there is a problem with the MPS to start the machine. We are trying to investigate whether it is related to the vacuum or something
else. |

IC, VM; Restart of the accelerator
|
09h35 Start-up modulator
09h52 Start the fridge
09h55 Start chillers |

08h26 Start-up modulator, laser, fridge, chillers, cycling
09h31 Low SF6 pressure => JN helped
11h HV ON. We do not see the RF signals, even the baselines (RedPitaya). |
