8h30 : accès casemate controlé 

==> septum et kickers OFF et cavité RF OFF

==> problème cavité RF, mux 3 défaut de communication

==> impossible d'acquité les interlocks et redémarrer la cavité.

Morning restart of machine was easy for the same parameters from day before.

 

Problem with network was fixed by G. Philippon, it was due to the limited number of allowed ports in the new swith that was recently replaced.

Still we cannot start RF Cavity with Jean Noel. Ampli is working, but no communication of Consigne from Tango to LLRF hardware.

14.30 Cavity on, getting power.

Frequency 500.41->500.4094, and phase manual optimisation.

Power in cavity is changing from 60 kV to 80kV for  80kV setpoint.

Saving data for postprocess. Orbit correction.

Beam is stable and stored. Orbit is positive. energy is about 50.075MeV, ring dipoles 160A. Sextupoles on.

Extraction kicker started to extract just before injection.
