Night work
Weekend
Report of work
- COM: It was found that calculation of finesse estimation from ring down measurement was wrong. It was actually Xarm ~1450(close to design value), Yarm ~440(1/3 of design value).
- Type Bp: Satellite box for PR2 was replaced. One new box was no signal at one of the channels. It was replaced to other new one and it worked.
Work plan
- CRY: ITMX cryostat cooler will be stopped.
- IOO: MZ will be released today from the main path of PSL.
- DGS: Maintenance work for adding BIO cards.
- DGS: Camera server maintenance. If you need camera, please use k1cam1.
