RE: PSS en alarme | |
A priori rien de grave, la langue du PSS était passé à l'anglais ce qui donnait des messages bizarres ... à vérifier que la langue est bien le français.

Shift "du Jeudi" : VM/HG/KD/DN/RC | |
09h35 Warmup ThomX
09h40 Cycling all magnets
09h50 Start Chillers
09h48 HV is ON
The reflected wave from the RF gun seems too high. Trying to set it to 27°C, but the clarinet temperature rises to 30.4°C and does not change.
10h15 HV is OFF
10h27 Stop the Gun chiller.
10h50 Start the RF Gun chiller. The temperature is constantly rising.
11h25 Kevin reloaded the RF gun chiller. All is OK
17h00 Beam is in the ring. Receipt was loaded from 10/04/2025 17:32, RCDS, Good storage, Orbit adjustment to measure bunch length with MRSV. There is the light on the camera. Receipt saved 09102025 17:07
Emittance measurements during the shift as well, at QP1, QP2 QP3 with low charge 70pC(0.8 mm) normal charge 100pC(1.3mm) and (300pC)3mm : here we wanted to see the affect of asymetric laser beam as well.
QP4-Scan also but scan is strange (and long ... 1s expo to see something)

Charge avec ou sans l'Iris sur le laser |
|
Nous avons testé de retirer l'iris pour mesurer la charge.
la charge max passe de 100 pC max à 150 pC. Le bruit semble aussi plus important (plus de dispersion sur la charge).

08h30 Warm-up ThomX: Modulator, Laser, Fridge
08h36 Chillers were started, cycling all magnets
09h33 HV is ON
09h34 HV set to 1215 V RF Gun phase is 188 dg.
11h09 Help needed! Something is wrong with the TL bends.
11h44 Something is wrong with the section attenuator. Reducing the attenuation results in a decrease in the section's output power.
12h15 OK, finally we got it. RF Gun phase 182 dg. Sect. phase 298 dg. Sect. Att. 0.59 dB, 50 MeV, Li/HFI/ATT.01-MOT.01 ==> 311 steps Sect. Output -0.123 V
Sect. Output -0.123 V Mot. pos. 1699 steps but Sect phase = 211 dg. Calc/Li/HFI/ATT.01-MOT.01 is not working properly.
