Progress report

General

  • O3GK Noise Budget paper [Washimi] : The paper writing team (Kokeyama, KYamamoto, Washimi) is writing the draft.
    • Seismic noise through Type-A tower : on going
      • This noise is evaluated by the TF (Shoda-san's simulation). -> Does it include the actual situation of GAS filters? -> Maybe "yes" (by Miyo-kun)

    • Type-A ctrl : on going
    • Type-B ctrl : almost written. Please check it.
    • Type-Bp ctrl : almost written. Please check it.

  • Implemented the cabling for cryo-payload in IX.
  • Assembled the connector cables for ACCs.
  • Assembled the geophone pods for ITMY.
