Zoom Meeting

CRY+VIS Interface Meeting

Date : 13:30-

Participants :

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 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:
Overall commissioning: Schedule meeting is requested (after JPS meeting?).

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？

O3GK Noise Budget : Seismic noise through the Type-A tower
- https://gokagra.slack.com/archives/C015M111B5G/p1611978135005400
- Calculation for the ETMY : much smaller than O3GK sensitivity, but larger than the design sensitivity
