8:40 Start warming up, problem with PSS. It was restarted.
Problems to start and tune the RF cavity. A clear working procedure and reliable tuning should b defined to optimize the Ring comissioning progress.
Feedback for teh RF has the suspicious behavior. At motor position close to the nominal, the feedback ofsets the motor in the negative direction |

In the morning, after the start-up pf the machine, scan phase-charge and small tuning it was possible to store the beam with the settings from previous
day.
The storage was optimize withthe dipole current of 159.9 (best storage up to now). RF cqvity voltqge 20-100 kV. |

VK, IC. VM, LS; Studies on the beam revolution frequency 12x
|
The main task for today is to measure the revolution frequency without RF cavity with the spectrum analyzer.
Start-up of the machine.
After setting the previous setting, the orbit was very different. We checked the injector, the beam also was different (based on the beam images) |
|
ND, LS, IC, VK, VM; Studies on the Ring revolution frequency 8x
|
Goal: understanding of teh beam natural revolution frequency. Study the effect of the dipoles.
We have started from the previous setting of the machine. Then we loaded the settings from last december and received better storage. RF cavity
is OFF. |

Bonjour,
Pouvez vous enregistrer les images de l'oscilloscope et le donnée brute à la place des screenshots. Il y a une option dans
l'interface web pour enregistrer l'oscillogramme "proprement". De même pour les images, cela permet de faire des traitements à |

|
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.

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. |
