12:10 : QP7 Scan 1 (Phase section 210) optimum sur ligne dispersive 
12:12 : QP7 Scan 1 (Phase section 213) largeur spot diminue 
12:15 : QP7 Scan 1 (Phase section 215) largeur spot Augmente  

Distribution du laser donne un faisceau avec plusieurs coeurs (sur QP7 etc ou lors de quad scans).

Suite à faire :

- Mesurer la dispersion. 
- comprendre pourquoi en Y on n'est pas très bon (QP7) 
- revoir les mesures de twiss : les distributions ne sont pas très bonnes pour le quad scan

Shift Program

  • Start the Archivage OK

  • Align 50 MeV beam in QP1 QP3 with Kevin script

  • TL_bpm2 : adjust espread and put beam at x=0

  • Store the beam in the ring with an orbit as flat as possible around the IP

  • Make a vertical FPC scan - Then put the table at maximum OK

  • Align the CdTe spectro on the on-axis position, approximatively by eyes with the Photonic science camera ==> take a spectrum OK

  • Change gun phase only  OK

in positive direction   ==> take a spectrum
return to "nominal"      ==> spectrum
in negative direction ==> spectrum
return to "nominal"      ==> spectrum
  • Change section attenuator only ==> idem (positive, "nominal", negative, "nominal") ==> 4 spectra  OK

  • Change the section phase only ==> idem ==> 4 spectra  OK

To not be affected too much by the motor hysteresis and by the boucle d'eau, "nominal" means that the beam has to return to its previous X position on TL_bpm2

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.

Analyse de l'amplitude des pulses du septum (cf plot en mode persistance): Bruit de l'ordre de 5mV sur 850mV.

Le kicker tire quand l'impulsion du septum n'est pas au maximum.

16h30 EL quads: [-3.67; 4.2; 0.0; -4.08;  3.8; 2.57; -2.54] A (from simulation). Ext. kiker 7422 V. There is image on the EL SST.01 (saved). 

16h35 Stop ThomX

Image processing results from the EL/DG/SST.01 camera. The resolution of the target image is 9.8 μm/pixel (horizontally).

The rms width of the horizontal beam profile (Gaussian approximation) is 325 pixels or 3.2 mm (see the figure uploaded). The simulated dispersion at the screen is about 1 m, so the rms energy spread is 0.32%.

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)
