Minutes

External Review candidate dates
- To be determined by Densuke
External Review topics
- Materials for the review will be distributed in advance of the review
- Misunderstandings between ourselves in what is technical and what is management
- Better to show what are the current issues recognized by ourselves and our planned means to solve them
  - With a Gantt chart including uncertain points
- Topics for the External Review
  - Daily alignment
  - ASC commissioning and simulations
    - Including reports from the site, by Kenta Tanaka and Chiaki Hirose.
  - Gantt chart for O4 (if possible)
Action Items
- Determine the review date
- Hold a meeting to summarize current WFS commissioning/simulation situations
- Ask what is the situation with FINESSE GUI development

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
    - What is the status of ASC simulations and commissioning? PRMI and DRMI?
    - FPMI
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
