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 |

Ronic Chiche | Under Process | report | mechanics | lasers and optics | detectors and electronics | ThomX igloo | day by day run for X-ray production | at the begining of the day, we started
to get ~81kW in the FPC for 33% amplifier
ratio and after ~1h, we got 84kW after CEP |
