Attention lorsque le modulateur est arreté il n  y a plus interlock vide ===> l'atténuateur continue de baisser  ==> danger lorsque le modulateur reearmer avec atténuation basse ==> penser à modifier le code

8h50 Warming up the machine

Problem with the vaccum around the RF cavity (see screenshot attached). Intervention of vacuum team is needed.

Mohamed is installing the powermeter to monitor the incomingt RF power for the accelerating structure.

Laser camera should be checked before the beam start-up

Due to the vaccum cable connector we can not start the beam.

8h50 Warming up the machine

10h start the beam

Tuning the injector

Beam is injected in the ring.

Problem to start the RF cavity (no injected power, the delta f jumps a lot and the motor position can not converge). Mohamed is contacted.

Problem to restart the DS for the control of the FP cavity table. The CC team is contacted. We are waiting for intervention.

Check of the Ring frequency

11h25 Modulator on stand by

Thanks to Kevin and Mohamed the RF cavity is OK. Restqrt of te beam.

In parallel, Vincent, Ronic and Kevin are investigating the sunchro with the FPC.

The injector is very unstable in energy (random slow change on the TL BPM 2 + usual problem with attenuator ) and LIL phase change/drift (from 114 to 88 deg. during the day). Presence of misstrigering from time to time during the day.

For a certain parameters, a good storage was obtained. But then, due to change of injector parameters the conditions were not kept. Work on the BBA.

Very difficult to work in such conditions, especially on BBA.

  854   Tue Mar 5 15:10:32 2024 IC, VM, VKUnder ProcessShift summaryRing Commissioning Restart and tuning of the injector 

10h Intervention to repair the water leakage. It was repaired.

New problem with vacuum pomp is found in the ring. The two problems are due to the water leakage. Intervention is ongoing.

12h Warm up of the machine

14h30 Start up of the machine in the mode LI-TL-EL. Goal: tune the injector and perform the measurements.

Mistriggering. All interfaces to see the current freauency do not respond.

Intervention of synchronization team is needed to continue.

15h30 Stop the beam for vacuum intervention .

08h50 Start up of the machine

- Problem  with the vaccum, the valves around the RF cavity are down. Eric came. He checked and the problem is with the cable. it should be changed. Intervention is ongoing.

- The water leakage is detected on teh Ring RF cavity. Intervention of Mohamed and Jean-Noel is needed. Jean-Noel is informed  about the problem.

- Synchro problem. Jitter at FPCavity scope screen. Vincent is working on that.

8h50 Start of the machine

Laser amplifier was somehow OFF. Very strange situation and not clear why it happen. To be understood.

Call Viktor, who came and start the laser.

Start the beam. No beam. No e- from gun. Call Vincent.

Many instabilities in e-beam signals.

Retuning Linac, attenuator =2.114  for 50 MeV (why ??? calibration problem ?)

Work on orbit correction, starting from natural one. Slight optics tuning. Frequency 500.067 MHz. The hor. tune is 0.18

Small horizontal, small vertical steerers.

At some aatenuator or frequency values, the energy jitter appears and a lot of mistriggers.

Good storage obtained. Recipie saved : recipe_recipe_LI_TL_RI_good_20240301_15_50_35.txt

For TL orbit and Ring Orbit see screenshots.

 

 

 

 

 

 

16.10 Stop machine. Ronic, Daniele need access for FP Cavity.

Beam from RF gun is double kernel.

Start without RF. Search corrrect settings for TL: energy, position, dipole.

Orbit is the same with and wo RF

Fine scan in RF +- 3 kHz. Horizonatal Tune 0.17

Beam at TL becomes unstable after 14h. See screenshot. Data taken. We could not solve this problem , it is wery confusing to work with such energy jitter.

8h20 : Mise en chauffe de la machine pour shift de la journée

Charge Phase : 

Remarque sur les scan charge phase pour trouver l'energie Max:

en fonction des outils utilisés et des consignes des experts de dynamique faisceau, le choix de la phase à Energie max varie de 10°

soft de Nicolas : automatique 180° (phase charge max (juste avant perte charge)  240°  ) => E max --- Qmax- 60°

calcul de Hayg : 185° (à l'oeuil  phase charge max (juste avant perte charge)  235°)   => Emax ---- Q max - 50°

Sotf de Kevin :  182°   semi auto   (automatique phase charge max (jhaut de la courbe)  232°  )   => Emax --- Qmax - 50°

Qui a raison? 

 

Oscillations dans les BPMs (TL): 

Oscillations observées dans TL/DG/BPM02
ainsi que dans le PiC, voir la PJ
Les data de la RF (trend) sont dans le dossier du jour. 

Injection dans l'anneau : 

la recette a fonctionné pour une injection dans l'anneau. 

Optimisation : Xopt
Elle a retrouvé une injection correcte. A creuser pour garder la meilleure solution.

Coordinator: ND

9h12: Modulator start

PSS: Default centrale SSI

10h30 Beam

Load recipe: LI_TL_straight_test_20231027_11_21_15

12:15 Lunch break

Strange message left on one of the computer screens.

14:15: The shutter was moved over lunch time without it being logged.

14h20 Access to check MRSV

14h40 Restart beam

Some signal observed beam on and not beam off. But strongly misaligned.

Several access, trying to align the MRSV. No luck. More time to be spent on it.

17h30 Stop beam

La clé PA est resté enclenchée hier. Il faut penser à la tourner avant de partir (demande de Maher)

8h15 : Mise en chauffe machine (aimants, chillers, laser, modulateur).

Pas de mesure de charge (WAC, délai ?)

 

Recherche de la cause de la perte de puissance

** Klystron 1090 ==> 2MW en Pi Load

Initial : TL/BPM.02 à 0 (Dipôle 160.8A) ==> 1.27dB

On test les sources de pertes de puissance :

* Changement frequence RF (-500Hz)

pas de changement

* Changement temperature section ( consigne 29.5°C ==> 29.2°C)

TL/BPM.02 à 0 ==> 1.39dB

On continue pour trouver l'optimum

optimum trouvé autour de 27.0°C en consigne.

TL/BPM.02 à 0 ==> 1.73dB

 

** Essaie de rentrer dans l'anneau. Impossible de faire un tour. Reprise du septum, on gagne 2 BPM mais les deux dernier ne voit pas de faisceau.

==> problème de délai des EP ?

Hier modification du retard du laser PC pour vérifier que l'on était bien dans l'impulsion RF au niveau de la section LIL. Passage du retard de -8.2µ à -8.4µs (pas de changement sur l'energie faisceau)

 

remise du retard à -8.2µs

parametre pour mardi

recette good for Xray and EL opérationel  (atténuateur section 1.385dB   29.2°C)

Arret machine
