9h07 : Mise en chauffe (frigo/chiller, modulateur, laser, cyclage)

FPC laser stability and lock observation.

Change the RF frequency to work at 50 MeV. Tuning of the FPC.

The recette "Flat orbit"

During the day we observe the very big variation of the synchrotron oscillation amplitude (very difficult to find the ring working conditions) in the ring, sudden charge variation.

14h40 measurement of the synch osillations for 200 injections

Amplitude deviation = 33.3028%
Frequency deviation = 0.91508% (267.9607 kHz)
Phase deviation = 46.4524 degrees orbit
Average position deviation = 1.4408%
