16h12 Problem with sudden change of params.
Recepies did nopt store corrected orbit: due to erro in EL steerer.
In continuation to yesterday study Jean Noel soldered in parallel 33 ohm : effect on orbit visible . Need to find correct shunt resistance (temperature) and power > 10 W.
Power supply does not show any sign of problem.

11h00 Beam is in the ring. Receipt 70 MeV from references BPM TL2 X=-1 mm
11h30 HV went standby. Maher fixed it.
11h32 HV is 'ON'
BPM transmission does not work properly (see screenshot)
Good storage at 70 MeV with the receipt.
Laser phase adjustment during the shift a few times
Work on the BBA at 70 MeV
For this, measurement of the ORM. There is a differennce with the model ORM. Attempts to tune the ring from the model. Work should be continued.
Due to this, only manual BBA can be done at the moment.
Starting also to adress the manual BBA in the TL. We used HCOR2 and QP5 and TL BPM.03. The results are not clear (big element-to-element distances). To be continued.

Good storage and MRSV beam size is restored. X- ray flux is about 20 kpA
At every point the streak camera data is saved.
Taking the spectra
*** Results (all files in data shared, streak, PhotonicScience, spectrum) ***
An error was made during the source size measurement of the usual working point (230A), no beam size available for that recipe (from previous measurement e- [H,V] = [180, 120], to be confirmed)
--- Bunch length (cf. curve)
The preliminary analysis show that the bunch length seems to not be affected by the recipe used. The 230A recipe show a longer bunch but it is not very significatif due to the machine stability.
--- bunch size
242A (in the morning) : e- [H,V] = [141 um, 56 um]
242A (in the afternoon) : e- [H,V] = [154 um, 58 um] (same as in the morning)
242A after optimization : e- [H,V] = [107 um, 62 um]
238A : e- [H,V] = [161 um, 92 um]

Bilan du 25 juin 2021 : commissioning linac | |
-Le canon a été mesuré à bas niveau sur place et en salle RF
-Les premiers diagnostics montrent qu’allonger la cathode permet de rattraper la fréquence, même si il restera certainement un déséquilibre des amplitudes de champ dans chaque cellule
-Le canon spare se poursuit, et sera probablement disponible à la fin de l’année
-Nous préférons disposer d’un canon au plus tôt même en mode dégradé afin de continuer la mise en route et le debugage des équipements en faisceau
-Le canon est démonté du linac, la vanne entre le canon et la section doit impérativement restée fermée
-La charge est montée sur la branche RF canon, le reseau a été testé aux fuites et remis sous SF6
-Refroidissement nécessaire de la charge ?
-Mohamed a organisé le conditionnement de la section LIL avec Hayg, Maher et Jean-Noel en support
-Nourredine et le groupe vide ont modifier les autorisations MPS pour rendre le conditionnement de la section LIL possible, pas possible si défaut vide sur un des volumes du linac
-Préparation des ICT, la faraday et l’écran bout de ligne (loin de la section) ?
-Problème sur le circuit d’eau constaté jeudi à intervention Dalkia ?
-Nécéssaire pour le conditionnement de la section LIL
•Rattrapage du canon (disponibilité courant septembre)
•Conditionnement de la section LIL (à partir de lundi 28 juin en présence de JP Pollina si la réparation Dalkia tient)
•lundi 28 juin 14h, intervention synchro et ICT (Mohamed+ Nicolas)
•Jeudi 31 juin 10h, intervention écran (Christelle + Nicolas)
•Casemate fermée toute la semaine

Soucis avec le modulateur
- Modulateur se met en chauffage suite à un interlock qu'on a pas pu identfifier
--> Attente 1h pour remettre en marche
- une fois qu'il mis en marche il repart pour 1h en chauffage ...
Oscilloscope RF :
accessible sur le réseau ThomX sous le nom oscillo3.thomx.fr
ensuite pour y accéder il suffit de passer par un navigateur WEB
Vérification Sortie du PA:
Le signal n'est pas carré comme prévu. Le cable est suspecté.
Il y avait un décalage entre l'impulsion HF et l'impulsion Klystron. décalée de 160 µs de l'impulstion déclenchement du modulateur.
Intervention de Nicolas pour la recaler.
Temperatures du Chiller
La temperature de consigne a été mise à 29.20°C pour avoir 30°C au niveau de la section (clarinette).
Une adaptations des coéficients de calibration Volt --> °C sera faite pour avoir bien 30°C de consigne pour 30°C à la Clarinette.

problèmes pour démarrer, il se met encore en défait pendant la periode de chauffe. Le probleme vu hier n'est donc pas réglé. |

RE: Interventon Modulateur | |
soucis Modulateur toujours pas réglé. Un signal (dans un module d'automate du modulateur) semble poser problème.
Maher a contacté scandinova.

Demarrage machine | |
Démarrage :
Rondiers : coup de poing d'arret d'urgence étaient enfoncés, on a du appeler Harold pour nous aider à débloquer la porte arrière de la casemate.
- Moduleteur en TRIG,
- RF OK
Atténuateur Canon et Section : 2dB
Modulateur tombé sans message d'erreur, on a pu redémarrer rapidement.
16h36 : Modulateur tombé encore sans message d'erreur -> 16h41 ok
16h50 : Charge phase : Qmax 85 pC pour phase = 120 ° (données dans : /data/shared/Commissioning_tools/Mesure/20220113/Charge_phase/)
17h25 : modification des pas moteur du Moteur M5 du laser par Kevin. Passage de 20 à 200 steps par revolution.
Alignement du Laser : Données sur /data/shared/Commissioning_tools/Mesure/20220113/Align_laser/
--> meilleure position :
pas X : 135
pas Y: 5420
sur les positions du spot sur la camera laser:
mean x 1370.81 pixels +/- 2.37 pixels
mean y 671.66 pixels +/- 3.25 pixels
positions ont changé depuis que l'iris a été modifié. La position devrait encore bouger, Viktor devrait replacer le spot laser au centre de l'image.
Charge phase pour differentes tailles d'iris motorisé
taille initiale : -9948
taille : -13726 --> diaphragme plus ouvert (image 18_14_47 en pj)
Charge phase @ 18h17 --> charge max 140 pC
taille : -3331 --> image 18_36_40
Charge phase @ 18-33-57
18h39 : Modulateur tombé, sans message d'erreur. 2h de fonctionnement ! par contre on a perdu le HV .... 1h à attendre
18h45 --> On arrete

14h30 : Machine démarée :
15h20 : Modulateur en défaut faut attendre 1h ... --> du coup je vais manger 
17h00 : idem modulateur à nouveau OFF. Il faut comprendre, sinon les runs vont etre compliqués.
17h20 : FIN
Le Laser tourne tout le WE, Vincent a lancé une acquisition. |

message debit eau modulateur | |
un message de debit insuffisant est apparu ce matin (40 l/min au lieu de 80 l/min)
une intervention est demandée pour savoir si ce défaut est réel ou si il s'agit d'un disfonctionnement du débitmetre. |
