8h: mise en chauffe en remote (frigo/chillers, laser, modulateur, cyclage)

*** Programme : Mesure spectre et monochromateur à 61.5MeV (70MeV si le temps le permet)

61.5 MeV

09h35 HV is on
photocathod laser phase 62 dg.  The receipt 61p5MeV_20250703_12_56_55.txt loaded, going to 61.5 MeV (interlocks)
10h13 Beam is on TL/SST02. Sect. att. 0.992 dB, sect. phase 236 dg.
10h30 Aligned with QP1 - QP3, linac steerers: H [-0.2 -3.02], V [-2.55 3.22]
11h05 Beam is in the ring W/O RF with all ring correctors set to zero

RF 100 kV storage is good, but can't correct the orbit  at 61.5 MeV :  le faisceau est presque hors du tube ==> Try to go to 70 MeV

70 MeV

13h20 RF processing the section on 25 pps by increasing pulse length from 1 us to 3 us
13h56 70 MeV, Linac steerers H [0.21 -3.75], V [-2.84 3.33], sect. att 0.18, phase 255 dg. laser phase 56 dg. (On the base of 70_MeV_Vert_tune 0.66_good_20251212_13_56_38.txt)
16h17 recipe_recipe_LI_TL_RI_good_20260318_16_17_14.txt saved, screenshots, RF 100 kV, phase -36 dg., Freq. 500.031645 MHz

L'orbite n'est pas la meme que pour 50 MeV  ==> Checks spectres dromadaires a V+40 

X_fpc = -1.5 / -1.3 / -1.7 / -1.9 / -1.1  mais on a oublie d'ajuster la phase a chaque fois  .... meme phase (3.0 V) 
X_fpc = -0.9 / -0.7 / -0.4 / -0.2 / -0.5  en ajustant la phase a chaque fois
Cf les 2 screenshots "Spectre 70 MeV"

On se place a X_fpc = -1 mm (pas top mais dans l'urgence on se met la)

Fente2 centrees a l'oeil : [H , V] = [11 , -23]
Prise de spectres a +/- 10 en H et V  (a voir ce que ca donne offline)

17h56 ThomX was stopped

Redémarrage ThomX :

     * remise en pression d'eau sur la boucle principale (légèrement inférieur à 4bars à l'arret).

     * PSS HS (écran freezé) ==> rémarrage de l'écran de l'automate (nécessite la clé de l'armoire)

     * mise en chauffe du modulateur (9h)

 

Programme journée :

   * essaie d'alignement automatique (laser photoCathode + quad)

   * génération d'une recette pour injection dans l'anneau (mesure émittance + énergie)

   * Tests correction orbite TL

 

*********

* L'alignement automatique du laser sur la PhotoCathode semble fonctionner mais est très bruité dû au bruit sur les BPM (~1mm en X)

De plus il y a une saturation sur les BPM (LI et TL/BPM.01 au moins), cf. Screenshot ==> cela doit destabiliser l'alignement automatique.

* Alignement Steerer VS QP, même constat que pour la photocathode. Le bruit des BPM limite la résolution de l'algorithme

* Mesure Alignement QP de la TL ==> manque données BPM pour TL/BPM.04 (mean, std des positions)

FPC laser stability and lock observation.

Change the RF frequency to work at 50 MeV. Tuning of the FPC.

The recette "Flat orbit"

During the day we observe the very big variation of the synchrotron oscillation amplitude (very difficult to find the ring working conditions) in the ring, sudden charge variation.

14h40 measurement of the synch osillations for 200 injections

Amplitude deviation = 33.3028%
Frequency deviation = 0.91508% (267.9607 kHz)
Phase deviation = 46.4524 degrees orbit

8h: mise en chauffe en remote (chiller/frigo, laser, modulateur, cyclage)

* cannot enter to the ring with the recipe "40_MeV_Enough_Good_20251211_14_07_28", probably due to mis alignment procedure of the QP1-QP3.
* reset de TL steerers with the recipe "40MeV_20250401_15_09_50", first turn ok but no storage.
* steerers Ring to 0.

12h --> back to previous cathod point (last week tuning was done at that position)

  • TEST/HL/ThomX_PhotoCathode/Horizontal_Iris_Position_set : <type 'float'> : 4.714
  • TEST/HL/ThomX_PhotoCathode/Vertical_Iris_Position_set : <type 'float'> : 3.524

17h: essaie avec la recette initial de mardi "recipe_recipe_LI_TL_RI_all_20251209_17_54_51.txt"

==> difficile de retouver le TBTsum de mardi, ==> après quelques ajustements (rcds, etc). on retrouve quelques choses de passable

==> MRSV totalement différent: long, étalé et pas au même endroit (à droite au lieu d'être hors écran à gauche)

==> problème de répétabilité. La seule différence est la température de la section. 

 

*** Scan FPC table (~16h) - A l'oeil FWHM ~ 300 microns ==> rms ~ 128 ==> sig_ele_Vert ~ 107 ==> sig_Source_Vert ~ 60 microns

Bilan imagerie du jour :
tres bas flux et faisceau tres instable .==>  Pas de contraste de phase visible. On espere que demain sera mieux !

Mesure imagerie X à basse énergie (40MeV)

 

  656   Thu Dec 15 13:11:15 2022 KDUnder ProcessShift summaryLI | Laser | Linac Commissionning shift du 15 decembre 2022, entered from 134.158.195.141 

12h : intervention casemate sur laser photocathode.

énergie mesurée sur différents points de fonctionnement :

Sortie Laser : 230uJ

Point de fonctionnement initial : position iris 5.82 / 3.59, ouverture 3 mm, attenuateur 410 mm
Sortie Transport Laser : 190uJ
Sortie Iris : 160uJ Injection canon : 120 uJ

Initial + Mouvement M4 : position Iris 5.42 / 5.39
Injection Canon : 120 uJ

Initial + Mouvement M5 : -50 pas moteur sur M5_MOT.02
Sortie TL : 190 uJ
Injection Canon 110 uJ

==> rien n'explique au niveau de la table PhotoCathode la baisse de charge des jours précédent.

Inspection du hublot d'entrée canon:
 * Hublot plein de poussières.
 * Nettoyage de la face avant du hublot (acetone + friction seche pour retirer les résidus de l'acetone). Il reste de la poussière sur la face arrière du hublot. ==> intervention nécessaire au niveau du hublot.
 * Pas d'impact laser visible sur la surface au niveau du spot laser (quelques goutes et rayure en bas du hublot)

Inspection du miroir de renvoie sous vide impossible.

13h20 : Démarrage faisceau

aucun écran SST et Laser accessible. Erreur dans lors du lancement :

Traceback (most recent call last): File "/data/shared/Interfaces/panneaux//Diags/interface_SST/IHM_SST.py", line 479, in master = SST_Control() File "/data/shared/Interfaces/panneaux//Diags/interface_SST/IHM_SST.py", line 127, in __init__ self.Image_camera = controled_image(save_path = self.attributs["SAVE_PATH"]) # nouvelle version File "/tmp_mnt/data/shared/Interfaces/panneaux/Diags/interface_SST/controled_image.py", line 331, in __init__ self.intensity_setting.setModel(synchro_tools.get_element_delay_tango_name("Diag",self.camera_delay_channel)) AttributeError: 'module' object has no attribute 'get_element_delay_tango_name'

13h25 : mesure de charge Max

Position iris 5.82 / 3.59 : 69pC
Position iris 5.42 / 3.59 : 140pC
Position iris 5.02 / 3.59 : 180pC

==> problème lors de l'injection dans le canon.

  Draft   Tue Apr 15 08:10:35 2025 KDUnder ProcessShift summaryDiag | Laser | Opt | Linac Commissionning | Ring Commissioning shift du 15 avril 2025 

8h10 : mise en chauffe de la machine à distance (modulateur, chiller/frigo, cyclage)

* redémarrage des DS client5

* impossible de lancer le laser (il faut intervenir en local)

*  8h40 Timing opérationnel à 10Hz

  1137   Tue Oct 14 08:00:18 2025 KDUnder ProcessShift summaryLinac Commissionning | Ring Commissioning shift du 14 octobre 2025 

7h55: mise en chauffe en remote (laser, frigo/chiller, modulateur, cyclage)

==> Nouvelle interface de cyclage, on ne voit plus la progression ou l'état des éléments. (impossible de savoir si le cyclage à bien fonctionné)

10h: recette chargée 50MeV 20251010_15_48_41

Commentaires machine :

* pour un bon stockage l'énergie n'est pas bonne (157.3A sur TL/DP pour etre à 0 TL/BPM.02), position vertical TL/BPM.02 ~ -4mm (stockage possible avec +- 2A sur TL/DP)

/!\ l'orbite n'est pas "flat" à l'IP (comparaison avec chargement de la recette "50MeV_100pC_flatVERTorbit_withEL_20250717_10_58_38.txt"), l'orbite n'est plus "plate" avec l'ancienne recette. 

* probleme dans la EL, le faisceau n'est pas extrait correctement avec la nouvelle recette. 

/!\ probleme BPM/EL, le BPM n'affiche plus la position du faisceau !

* comparaison orbite du matin et de l'après midi, l'orbite change en X pas en Y.

* décalage du délais septum de 4us pour mettre l'impulsion des kicker à peu pres au sommet de l'impulsion ==> il faut désendre le septum de ~ 2V dans ce cas (97.13V --> 95.33V)

** recette sauvée sous : 50MeV_100pC_MRSV_20251014_18_22_53

 

* mise à jour du DS "DS_Ring_RF" pour faire les changement de fréquence anneau et phase au meme endroit.

 

*** Prise de donnée ***

- échantillon chocolat : le plus riche en Cd ne fait pas appaitre de pics !

- Nb présent dans échantillon d'un patien "sain".
