Discussed recent orbit correction of the expanded orbit.
Need to make run with cavity detuning from its resonant conditions
used in the conditioning.
Discussed measurement of tune, and possible origins of inconsistant/noisy measurements.
Either BPMs signal processing or weak excitation. Beam size?
Need to do measurements with scope, to see if we can interpret TbT |

Regarding the remote control of the RF synthetizer: it can only be controlled via GPIB and RS-232.
=> Phase shift will be done from the synchro synthetiser
=> Power control can be done with a variable attenuator controlled by the synchro synthetiser or a delay generator. |

Notes from last week:
Beam was very unstable (probably energy instabilities), lot of time was spent tuning the injector.
Beam instabilities prevented
us from having a good storage.
Unable to start the extraction line dipole.

Summary of last week:
- On Thursday the beam energy was very different from usual (magnets current higher 172A for TL; 176A for RI) => made it impossible to re-use
previous settings for the ring and to find new settings. |

Excitation (betatron oscillation) on the beam observed by exciting it with the extraction kicker => initial measures of the tune.
Tune measured close from expected value.
Reason for oscillation damping is not understood. |

- Went up to 100kV in the cavity once it was tuned.
- Achieved nice storage stable for 2500 turns and some beam for > 100ms
- Measured the tune: several peaks around 0.35[1] (near the expected value) and one peak not understood at 0.5 |

Comments:
* There are strong evidences that part of the frequency problem comes from mechanical issue
* Fring field of the dipoles seems to be longer than anticipated. This could lead to shortening of the orbit. |
