Aujourd'hui on a detecte des X en mode desynchro (notre signal correspond a ~ 3.10**6 ph/sec)
*** Pour :
- 100 pC stockee pendant 100 ms
- 30 kW dans la cavite

9h45 Beam is ON. Scan charge vs. RF phase.
Attribute Li/OP/OPT.01-ATT.01 is showing value 340mm, this is different from the nominal ones of 300-303. Charge to be remeasured at nominal |

** Au vu de ce shift tres instructif d'aujourd'hui, pour demain:
1) Le sens le moins chronophage des scans table FPC sont:
Partir en Ty negatif, et aller vers Ty pos |

VK, IC. VM, AL, ND, LS; Orbit correction, optimization of the storage, study of the RF frequency 8x
|
9h30 Start of the modulator and lasser (GATE is closed).
9h46 Data is taken as background.
Cavity is tuned to 500.38 MHz. Optimization of the energy and phase. |
|
VK, IC. VM; Orbit correction, BLM in the Ring 7x
|
The BLM detector boxes were installed in the ring. We connected 3 fibers and 2 scintillator detectors in th ring to be able to observe the beam losses.
Cabling, connection and checks of the BLM without the beam.
Machine start-up. Modulator was switched on at ~9h30. |
|
VK, IC. VM; Srart of the beam physics measurements 14x
|
The main idea fo this week is to prepare the beam for the search of the first X-rays.
Start machine without RF cavity. During the day several reboot of the libera.02 (TL).
Study of the dispersion. Measurements of the horizontal dispersion by changing the injector energy (RF section attenuator). |
|
VK, IC. VM, ND, LS; beam storage
|
The main idea fo this week is to prepare the beam for the search of the first X-rays.
Start without RF cavity. Study of the orbit. Orbit correction. We menage to correct hor. and vert. orbit.
We put the RF cavity ON. A lot of interlocks during the day. Difficult to operate i this conditions. |

Effet de l'eclairage dans la casemate sur les detecteurs a RX (lumiere eteinte a 15:26:40) => il faut fonctionner avec la lumiere eteinte pour
plus de sensibilite. |

Bonjour,
avant d'arrêter completement de la machine il faut absolument fermer le "Gate laser" via
1, LI/OP/OPT.02-LAS.01-ASP.01 - Gate_int -False |

SC, ND; Effet changement de phase RF Canon sur TL/BPM.02
|
Quelques changements de phase canon. On voit que quand l'orbite derive vers des valeurs negatives sur Tl/BPM.02/SpX le fait de faire decroitre la
phase rattrappe la position...

Le code lock_position_tl_bpm_02.py a ete mis a jour pour prendre cet effet en compte.

VK, IC. VM; Reestablishing running conditions at 500.38 MHz
|
Goal of the shift: Reestablish the good storage at 500.38 and then try to optimize the storage and orbit.
Start up of the machine.
RF cavity start up by Mohamed. Water leakage. Jean-Noel will fix tomorrow mornig. Mohamed also says that aparently the sinal from ring syntetizer |
