Ronic Chiche | Under Process | report | mechanics | lasers and optics | detectors and electronics | ThomX igloo | day by day run for X-ray production | today with Alice, we planned to do a long
run with ~80kW in the FPC to check if the
lock problems are coming from the interaction |

Ronic Chiche | Under Process | report | mechanics | lasers and optics | detectors and electronics | ThomX igloo | day by day run for X-ray production | the RF frequency changed from 500.1003MHz
to 500.0913MHz => it reduced by 9kHz @
500MHz which is equivalent to 600Hz @ 33MHz |
