8h15 : démarrage de la chauffe (Frigo, Modulateur, laser)
Problème avec le login operateur (lent) et client1 freeze ==> redémarrage
~9h30 Access to the casemate to fix laser photodiode
The laser energy is 50 uJ
~10h00 Charge-phase scan
Phase Laser gun 130
~10h30 Injection in the ring. The full optimization should be done giben the change in the injection
phase RF section 116 deg. (was 89)
Good transport until the ring and good stability during the day.
12:00 Oscillations betatron observees dans l'anneau avec la cavite tunee and a bit of power ~100 W (see pictures)
Looking to improve number of turns in the cavity... Not possible to store the beam for more than ~10-20 turns.
La cavite a un effet en X (voir image ADC BPM)
We tried to measure the revolution frequency with the BPM connected to the scope. With the first analysis it is ~30*Frev = 499.87 MHz. To be checked. Several phase and freaquency scans with RF cavity. Usually working at 5-7 kW.
19h Machine stopped
