16h : passage à 8MeV

IC, VM; Restart of the accelerator

08h45 Start-up modulator, laser, magnets

09h38 Shutter Laser Linac is yellow. Tuning off the gun operation key does not change it to the red. Need help.

09h55 HV is on

09h56 HV is off. The fridge was started then chillers.

10h20 The laser shutter is OK. HV is on

It looks like RF cavity tuning does not work. Help is needed.

12h07 Mesure d'energie en sortie canon sur LISST1 en fonction du courant du steerer LI/PS/STR.01-H.01

'Energy=4.83MeV'

Several scans of the laser attenuator 200 to 430 at the Gun attenuator 0, 1, 2, 3 dB but at the same phase.

13h22 Standby

13h32 HV is on

15h17 Thomx was stopped

IC, VM; Restart of the accelerator

08h35 Start-up modulator (it was already on standby), laser, magnets, cycling.

As yesterday there is a problem with the MPS to start the machine. We are trying to investigate whether it is related to the vacuum or something else.

Problem with the solenoid COL.01 (Internal Interlock Hard).

Help is needed.

At this moment, apparently we are blocked by the closed vacuum valve of the FPC. To be checked with Nourredine (emails sent).

The vaccum level in the FPC is not yet good to open the valve. Eric will check it.

10h10 Switched to the Linac+TL+EL configuration. HV is on (the modulator was in the local mode). Interlocks even at HV 1200 V, the sect att. 3 dB. Linac 04 vac is high.

10h33 There are breakdowns at 26 dB the section att. and 25 dB of the RF gun att. These are not in vacuum breakdowns. Probably it is the klystron problem.

10h50 The modulator is in the standby mode.

Maher is coming to check the klystron and Jean-Noel is working on the solenoid power supplies.

11h40 Maher fixed problem with the klystron by increasing the filament power. At 84 kV, I = 48.7 A (microperveance 2.0). At 293 kV, I = 294 A (microperveance 1.85, should be 2.0).

12h03 The machine configuration without FP closes the photocathode laser shuter, so we can operate only in the Linac+TL+EL configuration.

12h36 Energy = 50 MeV, Laser Phase 25 dg., Sect. Phase 253 dg., Sect. Att. 2.26 dB, I_Gun -95.0704 pC, I_Linac -92.7397 pC, I_TL -3.7568 pC RF_Ampl. 0 kV, RF_Phase 35.5 dg.

Laser Att. 360, Linac steerers H: [0.31 -2.62], V: [-1.87 2.88]

12h43 Energy = 50 MeV, Laser Phase 26 dg., Sect. Phase 250 dg., Sect. Att. 2.35 dB, I_Gun -101.3924 pC, I_Linac -99.5194 pC, I_TL -101.3812 pC RF_Ampl. 0 kV, RF_Phase 35.5 dg.

13h17 Laser Att. 410 (max) Energy = 50 MeV, Laser Phase 26 dg., Sect. Phase 250 dg., Sect. Att. 2.35 dB, I_Gun -138.8712 pC, I_Linac -135.3968 pC, I_TL -137.4172 pC RF_Ampl. 0 kV, RF_Phase 35.5 dg.

At the moment maximum charge is 135 pC with irise Ø of 1.3 mm (possibly because the laser photocathode shutter is in the wrong position)

13h25 The modulator is in standby mode. Maher can remove the MPS short.

The problem with MPS is the OC/AVAL02 FP valve. It is in two states at the same time: Closed and Open.

It was the OC/AVAL01 FP valve

14h54 Beam is in the ring w/o RF. Thank you all !!!!.

15h15 Laser Att. 360, Energy = 50 MeV, Laser Phase 26 dg., Sect. Phase 250 dg., Sect. Att. 2.42 dB, I_Gun -179.1795 pC, I_Linac -205.8011 pC, I_TL -186.6367 pC RF_Ampl. 99.1184 kV, RF_Phase -50 dg.

Laser Att. set to 320 for 100 pC

17h41 ThomX was stopped

IC, VM; Restart of the accelerator

08h26 Start-up modulator, laser, fridge, chillers, cycling

09h31 Low SF6 pressure => JN helped

11h HV ON. We do not see the RF signals, even the baselines (RedPitaya). The Wevecatchers are also not triggered. probably problem with timing or their configs. Help is needed !!!

Apparently, there was the electricity cut. Help is also needed with the RF cavity.

12h10 something happened. Modulater went to OFF, dipoles are in error state. The valves became orange on the PSS screen.

Problem with Air Comprime => Solved !

JN et Maher heped to start again the Air Comprimee.

Mochamed fixed RF amplifier, but it gives only 10.7 kV.

Power supply of WAC3 is dead.

16h00 We had another problem (see photo).

16h15 The problem with valves was fixed

16h17 HV on

16h22 The RF gun's ICT was too low. Solution - increased the RF gun's attenuator to 1 dB, then returned it to 0 dB. Dark current corresponds to 15 mV

16h35 Solenoids are off (external error). the RF Gun IST shows 100 pC (Laser phase of 99 degrees). the section exit ICT shows 20 pC

16h52 ThomX was stopped

17h18 It seems resetting the red pitaya does not help

VC; redpitaya

Les redpitaya baie 17 'RF" ne "communiquent" plus avec JIVE.

IL faut les redémarrer... je ne sais pas faire!

Nicolas passe en fin de matinée pour essayer de les redémarrer

L'alignement de la PhotoCatode est fini. Il est a noter :

- La position de la camera a ete ajuste pour mieux coller a la distance entre PhotoCathode et miroir de prelevement (pour la cathode virtuelle). Cette distance est d'environ 215.5 cm.

- le tube a vide d'entre du laser dans le linac a ete retire pour s assurer de l alignement du laser sur le miroir sous vide. Le faisceau est centre en transverse et legerement au dessus de l horizontal en vertical (<3/4 du miroir environ)

- L'image de reference de l'alignement Photocathode est en piece jointe. Le faisceau est centre sur la camera.

- les alignement ont ete revu au niveau de la table de la casemate pour reduire le vignetage

- L'energie UV en sortie du laser etait de 140uJ environ.

Point a faire et a surveiller :

- Il faut remettre le tube d'injection et passer sous vide

- Il faut mesurer la puissance laser sur la table optique dans la casemate

- le shutter de securite semble disfonction en mode local. Il y a une repercution sur le PSS (defaut a aquitter)

- L'attenuateur ne semble pas tourner.

Le tube de liaison a ete remis, le faisceau etait legerement decale. Il a ete realigner sur la PhotoCathode (1mm a gauche de la sortie de la PhotoCathode trouee).

La nouvelle image et en P.J.

La référence sur la position moteurs des miroirs est :

li/op/las.01-mir.05 :

* mot.01 : - 0.180 mm

* mot.02 : - 1.035 mm

li/op/opt.01-mir.04 :

* mot.01 : 0 mm

* mot.02 : 27.01 mm

Je déconseille de se fier à cela. Il y a beaucoup d’hystérésis. Ce qui fait fois est la position sur la caméra.

Pour info : Compressor Position : 119988

Pour couper le Laser :

il faut arrêter seulement l'Ampli, et laisser l'oscillateur (pas besoin de l'arrêter).
Redémarrer l'oscillateur peut le mettre dans un mode instable.

La puissance laser aujourd'hui (23/11/2021) est de :

- Sortie laser : 200 uJ
- Sortie ligne de transport : 60 uJ
- Injecté dans le canon (iris ouverte à 100%) : 47 uJ

La transmission de la ligne de transport est en baisse. Les Hublots sont en cause. Il faut augmenter la taille sur le hublot ou changer le coating de ce dernier.

Hublot d'entrée retiré :

- Puissance laser sortie ligne de transport : 105 uJ

- Puissance iris ouverte 100% : 73 uJ

On retrouve la phase pour la charge max phi = 313 degres (consigne chiller canon = 31.25 degres)

On enlève 40 degres à la phase de charge max pour arriver à la phase d'énergie maximum phi = 273 degres

On focalise le faisceau avec la bobine de sortie canon I = 170 A

On peut l'observer sur la camera LI/DG/SST.01

On passe ensuite la section phi section = 100 degres (consigne chiller section 28.95 degres)

On met du courant dans le steerer avant section LI/PS/STR.02-V.01 I = 0.83A et LI/PS/STR.02-H.01 I = -0.90A

On observe sur TL/DG/SST.01

VK, AL, IC; Beam is stored 6x

Shift started at 18h

With the current injector settings, it was difficult to inject. We loaded the settings from last Friday 30/09 (19-22-04).

Principal steps:

- Correction of the one quadrupole polarity this morning

-injection tuning, observation of Turn-by-Turn-X, Turn-by-Turn-Y and Sum

-quads focusing, defocusing +-.0.5%

-iterative manual adjustments of corrctors, DPI, Septum, Kicker

-orbit correction with open line model response matrix

- several datasets taken for further postprocessing

Beam is stored !!!!! ~400 turns (limited by the Libera response)

Stored beam, visible more than 300 turns, signal decay as estimated due to Libera cutoff filters. To store more, RF cavity should be used.

Stable closed orbit!

Important milestone is achieved.

No losses at scintillator/fiber except for the injection, see oscilloscope screenshot.

Current machine settings are stored in recipe_recipe_LI_TL_RI_20221003_20_24_01.txt

Orbit is stable for more than one hour. End of the shift.

Programme de la prise de données du 8/06:

0) During warm up:

0a)check physically BPMs where there seem to be a polarity issue (needs 2 persons, a battery and a multimeter).

0b) CHeck vacuum chamber around RI-C2/AE/DP.04

1) Transport to TL/FC.01 (TL/DP.01 off). Record FC signal

2) Transport to TL/SST.02 and TL/BPM.02. Record BPM adc signal while closing dispersion (for Mouad's studies).

3) Transport to EL/FC.01. Record FC signal and compare with TL/FC.01. If needed swap filters and compare again.

4) Activate position feedback on TL/BPM.02

5) Inject in ring, no RF power. Record with high res oscilloscope travel time for different magnets settings. If needed use a mixer.

6) Study the effect of correctors around RI-C2/AE/DP.04

7) Use extraction kicker scan to measure beam travel time after several turns

8) Finish BPM polarities study

9) Repeat (5) and (7) with different RF powers at 2 different frequencies (500.0202MHz and 500.4MHz). Look at oscillations on TbtX and TbtY vs frequency.
