alignment with the new ring RF frequency.
I get back 50kW @ 33% amplifier ratio.

the FP-cavity to be sure there is no issue
due to the Linac section changing operation
  
  333   Tue Mar 26 10:20:54 2024 Ronic ChicheFixedinfolasers and optics | detectors and electronicsThomX iglooFP-cavity lock survey during the Linac section changing operationThis morning, I locked again the FP-cavity
at more than 50kW with 33% of laser amplifier
ratio.

of a plan mirror from the same batch than
the ThomX mirrors and we got ~ 1.75ppm instead
