== 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
  1. Simulation of WFS
   * IMC ASC closed but with larger noise and was turned off during O3GK.
   * IFO ASC not commissioned well. Too dirty beams.
    * https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=11687
    * https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=11061
    * https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=10996
   * 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
     * https://klog.icrr.u-tokyo.ac.jp/osl/?r=12133
     * https://klog.icrr.u-tokyo.ac.jp/osl/?r=11869

     * https://klog.icrr.u-tokyo.ac.jp/osl/?r=11537
  1. How to close ASC loops during the lock acquisition process
   * No idea
  1. 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
