- Alignment seems to be on schedule by this weekend if no more serious trouble happens.
- Hirose-san will come on Thursday and look at mirror surface or surface inside chamber.
- WAB is located pretty close to mirrors on ITMX and ITMY. The gap is only cm order, so it is not important to look at mirror surface, but no easy.
- Even if mirrors surface was dirty, we would have no way to clean through such small gaps.
- High sensitivity optical lever using Pcal beam looks good.
- Noise budget should be considered if the new oplevs are used in the mirror control loop.
- Commissioning team recommend to proceed it.
- SRM beam damp for intentionally misaligned SRM will be designed. It will be installed in summer as the same time as middle baffle.
- Next meeting: 2/12.
