Progress report

General

Type-A

  • The accelerometer with LVDT was tested at the site (report).

    • The ACC was set on the floor of IYV area. The folded pendulum was tuned to 0.24Hz. The servo loop was configured by Miyo-san using KAGRA digital system.
    • When we finished the final setting on Wednesday afternoon, the large earthquake (M7.8) was happened at Aleutian islands. So Miyo-san measured and evaluated the spectrum later.

Type-B

  • Paper: I finished writing. I'm waiting for Enzo's comments to submit to CPC and share it with the rest of VIS people.

Type-C

Controls

Electronics

Towards O4

  • KAGRA is in "Upgrade phase for O4". Upgrade of SR controls were performed. The accelerometer with LVDT was tested at the site.
  • Plan for cleaning the clean booth (EN, JP) will be submitted by 3rd. Aug. It is necessary to make the inventory with location (example for Type-A).

    • [Washimi] PEM team introduce the Holobuilder (Google street view like tool). Let's discuss about cleanup plan with this tool.

  • Preparation work (pre-cleaning) will be started from 17th Sep. Cleaning schedule.png.
