8h50 Warming up the machine

10h start the beam

Tuning the injector

Beam is injected in the ring.

Problem to start the RF cavity (no injected power, the delta f jumps a lot and the motor position can not converge). Mohamed is contacted.

Problem to restart the DS for the control of the FP cavity table. The CC team is contacted. We are waiting for intervention.

Check of the Ring frequency

11h25 Modulator on stand by

Thanks to Kevin and Mohamed the RF cavity is OK. Restqrt of te beam.

In parallel, Vincent, Ronic and Kevin are investigating the sunchro with the FPC.

The injector is very unstable in energy (random slow change on the TL BPM 2 + usual problem with attenuator ) and LIL phase change/drift (from 114 to 88 deg. during the day). Presence of misstrigering from time to time during the day.

For a certain parameters, a good storage was obtained. But then, due to change of injector parameters the conditions were not kept. Work on the BBA.

Very difficult to work in such conditions, especially on BBA.
