Agenda/Minutes
CRY+VIS Interface Meeting
Date : 13:30-13:45
Participants :
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？
