demarrage machine 8H50
Alim
EL/PS/DPI.01 demarrage à la main (ATK pannel)
ET/PS/DPI.01 demarrage à la main (ATK pannel)
Healthcheck OK 9H
ThomX warmup done.... wainting for modulator (around 9H50)
Beam from RF gun is double kernel.
Start without RF. Search corrrect settings for TL: energy, position, dipole.
Store orbit; Freq =500.0685 . RF on 100 Kv
Orbit is the same with and wo RF
12.30 Maher put dosimetry in bunker
Fine scan in RF +- 3 kHz. Horizonatal Tune 0.17
Beam at TL becomes unstable after 14h. See screenshot. Data taken. We could not solve this problem , it is wery confusing to work with such energy jitter.
