Agenda

External Review candidate dates
- 2021 August 3，4，5, 10, 11, 24, 25, 26
External Review topics
1. 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
2. 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
3. How to close ASC loops during the lock acquisition process
  - No idea
4. 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
