8h05: mise en chauffe en remote de la machine (modulateur, frigo/chiller, laser)

==> cyclage aimant plante, donc aimant non allumés ni cyclé.

9h All keys are in vertical position. Totes rondes sont tombees. We need help to restart.

Kevin and Vincent came to help.

All systems were started.

We switch on the RF and found problem with the reflected RF power in the gun. Checked the temperature and found that chiller failed to set the proper temperature.

10h10 Restart frigo+chiller

Several restarts but the temperature does not rise. 

After several attempts it is OK

11h Problem with laser, we do nto see the dark current on the ICT1; Try to understand the reason

Laser was not aligned. Kevin helped.

We restarted all the Liberas as they were not in a good state. 

The phase shifter DS was OFF.

11h50 Finally we have the beam in the ring

problem with the RIC1 STR 4 VERT It does not take the command and stays in the orange state. Steerer resistance is 18 Ohm.

12h02 F Gun phase 283 dg. Sect Att. 2.32 dB. Sect. phase 218 dg. Beam charges about -100 pC. Charge devices do not show values

Restart all Liberas because of reading problems

Srudies of the RF freq change. it is clear that it changes the phase of the RF cavity. Not clear if it is OK for th e measurements.

=> It is very important to measure the deltaPhase introduced by the RF transport lines in order to proceed with the measurements.

The vert cteere in the ring shuld be checked/repaired.

Stop for lunch and steerer reparation.

13h20 Jean-Noel came to help and check the steerer. Overvoltage on the PS. Access to the casemat. 

14h11 RIC1 STR 4 VERT fixed by Jean-Noel

14h14 HV is 'ON'

15h Studies of the vetical orbit and its compensation

17h Optics measurements.
