to get ~81kW in the FPC for 33% amplifier
ratio and after ~1h, we got 84kW after CEP

  384   Wed Dec 4 12:26:03 2024 Ronic ChicheUnder Processreportmechanics | lasers and optics | detectors and electronicsThomX iglooday by day run for X-ray productiontoday 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
  
  385   Wed Dec 4 17:11:50 2024 Ronic ChicheUnder Processreportmechanics | lasers and optics | detectors and electronicsThomX iglooday by day run for X-ray productionwe observed that :

- the MOT.03 motor always exhibits
some perturbations on the transmitted, reflected

we removed the threshold on the
FPC/RF error signal.
  
  387   Wed Dec 11 18:51:35 2024 Ronic ChicheUnder Processreportmechanics | lasers and optics | detectors and electronicsThomX iglooday by day run for X-ray productionThis morning, I added an amplifier on the
33MHz beating signal in between the mixer+LPF
and the scope/Laselock.

  389   Tue Dec 17 16:28:32 2024 Ronic ChicheUnder Processreportmechanics | lasers and optics | detectors and electronicsThomX iglooday by day run for X-ray productionthis morning, Kevin reduced the steering
current in the IcePap controllers of the
FP cavity motors.
  
  390   Tue Jan 7 10:18:08 2025 Ronic ChicheUnder Processreportmechanics | lasers and optics | detectors and electronicsThomX iglooday by day run for X-ray productionthis morning, I restarted the cavity after
the Christmas shutdown.
everything went fine.
  
  394   Thu Jan 23 17:55:41 2025 Ronic ChicheUnder Processreportmechanics | lasers and optics | detectors and electronicsThomX iglooday by day run for X-ray productiontoday we did x-rays => we got 41 000
pA at maximum and 90kW in the FPC for 33%
amplifier ratio.
  
  395   Thu Feb 6 10:29:36 2025 Ronic ChicheUnder Processreportmechanics | lasers and optics | detectors and electronicsThomX iglooday by day run for X-ray productionthis morning, I restarted the lock of the
CFP after almost 2 weeks without operation.
after quick alignment and CEP tuning,
  
  417   Tue Mar 18 11:25:07 2025 Ronic ChicheUnder Processreportmechanics | lasers and optics | detectors and electronicsThomX iglooday by day run for X-ray productionthis morning, the cavity was pretty misaligned
=> basic alignment in y direction helps
a lot => 93kW for 33% amp ratio.
  
  419   Mon Mar 31 17:12:56 2025 Ronic ChicheUnder Processreportmechanics | lasers and optics | detectors and electronicsThomX iglooday by day run for X-ray productiontoday, the alignment of FP cavity was so
bad that I tuned the 01 mode by error (CEP
and alignment)...  insead of the 00
  
  421   Tue Apr 29 09:26:08 2025 Ronic ChicheUnder Processreportmechanics | lasers and optics | detectors and electronicsThomX iglooday by day run for X-ray productiontoday, after 1 week of vacation, I was
able to easily lock the cavity with 92kW
with 33% amp ratio without too much optimizations
