Progress report

General

Type-A

  • [Miyo] Installed the Prequa system in TypeA

    • (This week) Installation was finished. Now I try to diagonalize sensors and balance actuators by using the Prequa system.
    • (Next week) I will do the modal damping on TypeA suspensions after the initialization work for sensors and actuators.

Type-B

  • On Monday I submitted the paper to CPC: JGW-P2011860.

  • Noise budget paper: I calculated upper limits to DAC and coil driver noise contribution to DARM for the BS: klog 14875.

Type-Bp

  • Noise budget paper: Fabian calculated upper limits to DAC and coil driver noise contribution to DARM for PRM: klog 14876.

Type-C

Controls

Electronics

Towards O4

  • KAGRA is in "Upgrade phase for O4". PreQua system was implemented to the Type-A.

  • Confirmation of personnel at the site.
    • Type-A team: Takahashi, Sato, Miyo, + Company(Jan-Apr)
    • Type-B/Bp team: (Shoda,) Hirata, Fabian, Washimi, + Company(Oct-Dec)
  • Procedure documents are required by SEO.

  • Schedule towards O4 (Chart) was revised.
