Minutes
Agenda
- External Review candidate dates
- 2021 August 3，4，5, 10, 11, 24, 25, 26
- External Review topics
- How to perform the daily alignment of IFO
Summary of alignment scheme in O3GK to RSE trial https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=12594
- We can present our improvement plans and also ask for further improvements necessary
- Simulation of WFS
- IMC ASC closed but with larger noise and was turned off during O3GK.
- IFO ASC not commissioned well. Too dirty beams.
- IFO ASC simulations so far
BRSE, PRFPMI, SRFPMI, FPMI https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=10359
- PRMI, DRMI simulations necessary
- Report on FINESSE simulation on IMC ASC by C. Hirose
- Probably better to be reported by site people
- What is the status of ASC simulations and commissioning? PRMI and DRMI?
- FPMI
- How to close ASC loops during the lock acquisition process
- No idea
- How to use local sensors, WFS signals and BPC, etc. to enhance stability and to minimize noise contribution
- No idea
- Probably better to be reported by suspension commissioning team
- How to perform the daily alignment of IFO
