Demarrage cyclage aimants

Start of the RF cavity 500.25 MHz and 50 kV

Start of the accelerator (mode THOMX on MPS)

Charge-phase scan, tuning of the RF section phase (Gun phase = 273, LIL phase = 114, Att = 1.35)

Transport to the Ring but only 1 turtn. Optimization of the injection but no big imrovement

Optimization of the transport

At 11h50 the modulator interlocked . Then on the MPS there are errorrs (see photo). Need the intervention of support.

13.50 Eric came and fixed the probmlem of one of vacuum valves of the ring, that was causing interlock.

Synchro problem, Kevin repaired.

14.40. Kevin , Ronic entered the bunker to change cable on FPC.

15.10 Restart the machine. Tune of the injector (gun phase 230 and LIL phase 111, charge 72 pC ICT1). it seems that now the energy is not very stable, at TL BPM2 the SpX goes from +2 to -6 (see the screenshot attached). Injection in the ring.

Restart of the RF cavity (problem to start from the interface in the control room)

Only one turn in the ring

During the phase scan of the RF cavity (with rigol) strange bahavior of the trigger. Misstriggering (see the screenshot attached). Problem to be understood. Conclusion: to change the phase of the RF cavity better to use the phase shifter (old position 6094 and nez position 2320).

Storage is reisteblished and improved after optization of the injection : the last good receip is

The injection stability to be further investigated (see the screenshot attached)

Use of the trigger on demand. Works well. Checked the duration of beam circulating in the ring (5-10 sec on the scope).

Some tests to check the correlqtino of the energy jumps on TL BPM2 with RF cavity and pulsed elements and dipoles. It seems that there are no effect.
