Agenda/Minutes

Zoom Meeting


CRY+VIS Interface Meeting

Date : 13:30-13:45

Participants :

Post O3 Upgrade portal

Schedule

  • IX: Setting Oplev by 3/10. Preparing additional spring for BF.
  • IY: Disconnection is scheduled on 3/11.
  • EX: Connection is scheduled in the week of 3/15.

Status

  • Corrugate tube fixing jig: Started the vent of IYV chamber on 26th. Re-measurement is on going in 2/25-3/2 at IYV.
  • Commissioning in air: Commissioning of IX will be delay. From April?
  • Commissioning in vacuum: From May?
  • 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: Assembling.
  • Overall commissioning: To be considered about personnel.

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?
