 * On Monday we removed the jigs from the F0 blades and began adjusting the compression by 2 mm at the time.
 * This work was mostly finished on Wednesday. We gave the jigs to Type-A team in the afternoon. Blades 1, 3, 4 and 5 still require some compression. See [[https://photos.app.goo.gl/nzXUoTYVzXdZVLir7|this notebook page for details]].
 * On Thursday we lowered the keystone and hooked the suspension rod. Then we lifted the keystone until there was some tension in the rod. We didn't proceed with the assembly of the keystone assembly because lifting the load would be required.
 * We installed and tested F0 vertical fishing roid switches. We checked the polarity of the motor also. It was correct.
 * We assembled the F0 yaw stepper motor, tested the limit switches and the polarity. We were all fine. We left the motor on IP table.
 * We took pictures of the IP horizontal fishing rods for Ikeda-san.

In PR3 we inspected the OSEM flags with the optic fibre camera. They all seem to be in place.

Agenda/Minutes

Zoom Meeting

CRY+VIS Interface Meeting

Date : 13:30-14:10

Participants : Takahashi, Sato, Ikeda, Ushiba, Kimura, Akutsu, Aso, Hirata, Miyo

Post O3 Upgrade portal

Schedule

  • IX: Oplev setting will be finished by 3/10. Mystery of 5-kg overload. The ballast on the F0 is too tall.
  • IY: The vent was finished on 3/2. Disconnection is scheduled on 3/11.
  • EX: Connection is scheduled in the week of 3/15.

Status

  • Corrugate tube fixing jig: Re-measurement was performed in 2/25-3/2 at IYV.
  • Commissioning in air: Commissioning of ITMX is delay. From June.
  • Commissioning in vacuum:
  • Acceptance check: Cryo-payload in IX/EX and Type-A tower in EY/IX are on going.
  • PF actuator: Not evaluated in IX, but after the commissioning for suspension.
  • Jig for FC painting:
  • Overall commissioning: Schedule meeting is requested (after JPS meeting?).
  • Procedure of TM height setting:

Discussion

  • [Miyo] オフロード作業を無くすためのアイデア募集
    • 問題意識：真空圧力が変わるとIPが傾いてPayloadが自身のEQフレームに当たる。（完全に傾かないようにする治具はそもそも不可能なので、傾いても大丈夫なアイデアがほしい。）

    • [Miyo] そもそも、IPが傾いてIPのEQストップに当たった状態でもPayloadも同じく当たらないよう十分に退避させれば良い話に思える。その場合、IPがEQに当たった状態でFRをつかってもとに戻せるかどうか確認すべき。これはAcceptanceCheckに追加すべきか？

VIS Meeting

14:10-15:30

Participants: Takahashi, Sato, Ikeda, Aso, Hirata, Miyo, Tanaka, Washimi, Sugiyama, Ishizaki, Fabian

Schedule

Schedule

* The next week

  • Type-A team: 3/9 IXV filter setting, 3/10-11 IYV payload disconnection
  • Type-B team: 3/9 EXV withdrawal, 3/10-12 PR/SR adjustment
