08h45 Start Thomx: Modulator, frigo, laser

08h50 Start chillers, cycling all magnets

Vacuum intervention, beam pipe closed. Vacuum OK to start (11.23)

Vacuum MPS off (Kevin)

Polarity of 2 vertical steerers in the ring :! ric1/str.06-v.01 and

ric2/str.02-v.01 were changed by Jean Noel, according to our request. 

11h20 HV is 'On'

RF Gun phase is 162 dg. Att. is 0.04 dB, Sect Att. is 2.62 dB, Phase is 212 dg. Charges: -107 pC, -112 pC, -117 pC

14h12 FPC table scan. Sigma y = 140um (receipt from 14h14). RF 150 kV

Accelerating section phase often needs  adjasment (from 106 dg. to 112 dg. )

Trying LOCO. 

14h51 the receipt from 14h14 loaded (saved before LOCO). The FPC table at X ray max. (X photodiode reading of 470 pA ). Ramp the RF cavity to 250 kV

14h58 Slava made RCDS on X photodiode readings by adjusting vertical steerers of the ring.   X photodiode reading is 500 pA

15h04 Receipt seved. X photodiode readings reaches 522 pA.

15h15 FPC table scan. Sigma y = 128 um (receipt from 14h14). RF 250 kV

15h22 RF Gun phase is 166 dg. Att. is 0.04 dB, Sect Att. is 2.62 dB, Phase is 212 dg.

Beam position at TL/BPM02 unstable from the trigger to the trigger, so the ring storage.

16h00 Going to 61.5 MeV. Sect Att. at 1.1 dB, phase 228 dg. RF at 500.04545 MHz, 50 kV TL/BPM02 X=+4mm

16h38 receipt saved. There is some storage, but orbit is wide

17h30 Optimized configuration for 61.5 MeV very good storaga the RF cavity at 500.04545 MHz => Rceipt good_20250124_17_36_24

Orbits with and without RF are close

17h40 Stop thomx
