Discussion

VIS Meeting

Date: 2022/12/23 13:30-

Participants: Takahashi, Uchiyama, Ushiba, Fabian, Mitsuhashi, Tanaka, Miyoki

Summary Report

Type-A

  • Replaced the flip cables in EXT. Pin #3 for H2 LVDT was grounded.
  • Investigating the sensitivities of the accelerometers in IX/IY.

Type-B

  • I've been working in the optimization of the sensor correction filter for F0 LVDT. I'm nor finished, and I'll report in a future meeting

Type-Bp

  • For PR2 and PRM SF and BF, I measured transfer functions with different amounts of actuation. The frequency of the resonant peaks changes with the amplitude of the actuation.

Type-C

Electronics

Control

Schedule

  • Type-A: Investigation of ACCs.
  • Type-B/Bp: Vertical sensor correction.
  • Type-C:

Safety

Discussion

  • Task list for the authorship 2023.

Travel Plans

(Date in Kamioka)

The week from 12/26

  • Hirata: 12/27-28
