shift du 12 mai 2025 : conditionnement GUN | |
8h: mise en chauffe modulateur et frigo/chiller
- problème de lecture de vide (visible sur toute les jauges LINAC)
--> Réparé : un switch (de fin de ligne etait on et mis OFF) |

8h: mise en chauffe à distance (modulateur, frigo/chiller, laser)
10h30: on a du faisceau atténuateur à 260pas pour 100pC.
Nouveau point cathode : [H,V] = [4.81, 3.62]
11h: stockage dans l'anneau avec la recette 50MeV de 100pC
Problem de lecture des charges (Wavecatcher) quand les kickers sont en marche (trig sur du bruit). Le problème n'existe pas quand le kicker est éteint.
17h: Variation de la charge uniquement (machine non touchée). Charge max ~ 500pC pour iris à 1.3mm
==> Stockage ok à 500pC (sans rien faire), il faut optimiser et regarder plus en détail car il n'y a pas un facteur 5 sur la charge stockée (juste 3).
18h : la charge (GUN) oscille, cf plot.
18h30 : soleno scans à differentes charges : 100 pC / 500 et 600 pC (max)
**** Programme ****
refaire du faisceau et retrouver le point de fonctionnement à 100pC avec la nouvelle cathode |

7h50: mise en chauffe à distance (Modulateur, chiller/frigo, laser)
cyclage aimant bug ==> impossible de cycler les aimants, trop de plantage
Soleno scan : Iris 0.5 mm --> on retrouve la symétrie : le laser donne cette dissymétrie ...
100pC et 150 pC
*** Programme ***
- refaire du faisceau de rayons X.
- Optimisation de l'injection (haute charge et/ou nouvelle lattice, cf. Viktor) |
