08h21 Thomx Started: modulator, frig, laser

08h27 Chillers started, cycling all magnets

09h32 HV is 'ON'

09h34 Cannot control the section attenuator

09h50 The issue with the section attenuator was fixed: its server was shut down and restarted, but it was set to 0 dB!!

11h17 RF Gun phase 171 dg., Sect phase is 211 dg. Att. 2.62 dB, TL/BPM2 X=2mm, Charges (from BPMs at Att. 31 dB): -77pC, -77pC, -86pC . Linac steerere: H [1.03 -3.47], V [-1.88 2.63]

Contradictions with ICTs:  -87 pC, -73 pC, -80 pC

11h40 RCDS on injection receipt all_20250418_11_39_40, RF cav. at 100 kV, phase 16.5 dg., screanshots

12h03 Linac was reajusted. RF Gun phase is 166 dg., sect. phase is 210 dg. Att. 2.58 dB, TL/BPM2 X=3 mm RF cav. 100 kV, phase 13.5 dg. screenshots

12h10 Ring dipoles were changed from 160.4 A to 159.3 A, ring quads were adjusted and tune as well was set back to 0.17. TL/BPM2 X = 0. Screenshots 

12h25 RF Gun phase was adjusted to 161 dg.

15:24 Initial Synchro delay for streak camera: -6.60us. Injection at delay of +99.3e3us

Measurements incuding single shots

Study of the injection and of long decays with the streak camera, cf images. Horizontal scale is 2ms, vertical scale is 600ps.

Operating the streak camera create instabilities on the ring 500MHz that may cause phase problems.

16h47 RF Gun phase is 149 dg. RF cav. was at  200 kV, phase 10.5 dg.
