10h30 Start beam

Since Friday evening the problem to store the beam at 70 MeV. There is 1 turn only. Probably some subsystem failure. At this moment the reason is not found. Help is needed: synchronization/Diag/Magnets.

Today morning the same situation. We came back to 50 MeV and the problem remains.

We checked dipoles with resistors, it looks fine. We are checking synchronization and laser, Diag delays.....

We found the problem is with kicker. looking now at this with Maher. The max value it accepts is 2500 V.

12h20 Maher wil restart the kicker at the hardware level. Maher is contacting SOLEIL.

12h30 The modulator has been set to standby mode.

Investigation of the problem with injection kicker.

Tomorrow tests with SOLEIL people.

16h30 Stop ThomX
