Minutes

Updates from Projects

• Finesse interface
  • Aiming the first version release during their visit
  • Added amplitude detectors
  • Figures were updated
  • Documenting how to GUI
  • Confirming if simulation results are correct
• Ifo model
  • Matrix change when SRM is coming from non-reso to reso in SRC will be calculated (DRMI)
• OMC model
  • Next steps is to inject the simulated AS beam to OMC. But HOM extension of the ifo model hasn't been done.
• Birefringence model

  • Haoyou's report link

  • With Hiro-san's help, we concluded S=>P conversion gets i phase shift!

  • The next problem is when we use BS to simulate bosh S and P worlds at the same time, we don't know how to set the phase

    • s=>p can be treated as loss giving up to simulate S and P worlds at the same time, but it ignores the second order effect (S=>P=>S).

    • There may be some solutions to manuplate the S=>P conversion map. We should look-back the conversion map calculation.

    • There may be an exotic solution on the Michelson phase?
