Simulation meeting 2020 Aug 12, 15:00-

Participants

IFO modeling
- Note on FPMI
  - Why not to use "diff" command (and its history)
  - Updated sensing matrix with "fsig" command
  - jupyter notebook on git was updated to use python3
  - Comparison v.s. analytical calculation
- Note on PRFPMI
  - Matrices do not match very much
  - Analytical calculations seems suspicious
- Next steps
  - DRFPMI model
  - Include the higher order modes (FPMI, PRFPMI, DRFPMI)
Birefringence modeling (Haoyou) Notes
- The couple cavity model can hardly reflect the real S-P conversion process as S and P modes have different responses to tunings of PRM.
- Carefully testing a simple PRC configuration with the S-P conversion using a fake BS. In the model using a BS to separate S and P, there is i multiplied for the BS transmission, which does not happen in the real S-P conversion process. It should be properly treated in Finesse.
- The phase factor i in the BS model is a problematic thing. We need to handle with it or find new modeling schemes.
OMC modeling (June Gyu)
- Building the OMC model. Possibly some initial results will be obtained in a week or so.
Simulation Interface
- Had the second lecture by Yuzu-san on Aug 5th
  - Installed Anaconda, Finesse2
  - Installation memo for Finesse (Koyama)

Hirose-san and Koyama-san will visit Kamioka
Yuzu-san will be in Kamioka for instruction from 17(Mon) afternoon to 26(Wed) evening.
