Realtime model for DRMI commissioning

  • Requests from commissioning team
    • Calibrated signals of MICH, PRCL, and SRCL.
    • 10-20% error for each DOF
    • ASAP after DRMI will be locked.
  • Current status of RT model.
    • Filter processes of MICH, PRCL, and SRCL are constructed.

      • dL = C-1 * ve + (ATM + AIM) * vc

    • Channels are not registered to DAQ yet.
    • There are no CAL line to PRM and SRM.

      • Is there any plan of low-latency/offline reconstruction? -> Darkhan and Sawada-san.

    • Gain drifts by time are not taken into account.
  • What we need.
    • Optical gain (and cav. pole of PRC and SRC).
    • Actuator efficiencies of TM and IM of BS, PRM, and SRM.

      • Maybe the approximations as f-2 and f-4 are enough for 10-20% error.
