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 |

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 | this morning, the cavity was pretty misaligned
=> basic alignment in y direction helps
a lot => 93kW for 33% amp ratio. |

Ronic Chiche | Under Process | report | mechanics | lasers and optics | detectors and electronics | ThomX igloo | day by day run for X-ray production | today, the alignment of FP cavity was so
bad that I tuned the 01 mode by error (CEP
and alignment)... insead of the 00 |
