Report of work
- COM: We are trying Y arm lock with mass feedback by GR signal.
- We saw some suppression on control signal but feeding back to DC had some fluctuation. Probably needs better setting on cross over frequency.
- In this. week DRMI will be tried.
- ETMY 80mHz problem is being hunt.
Work plan
- AOS: Preparation for TMX started at ETMY area.
