Discussion
- We need 2weeks more.
- Minimum success is stabilization of IR fluctuation to cavity resonant frequency.
- X arm lock
- 2hours lock was lost not by instability of VIS, by something but we are not sure.
- IR flashes could be seen with CARM lock, but it is not sure it was TEM00. We could know FSR of cavity by the measurement.
- Yarm commissioning
- Nakano-kun, Eleonora lead the Y arm commissioning task, and Sugimoto-kun can join to Y arm team. Enzo and Type B team can work for commissioning work specially for BS and SR.
- Laser, PSL, IOO report
