* [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? |

TypeA
- Disconnected the cryo-payload in IY.
- Setup the F0 and tuned the IP in IX.
TypeB
TypeBp
PR3
- At the begining of the week the IM was still touching the IRM.
- First we did a health check of the IM-Y picomotor because I had the impression it had reached a limit.
- We locked the BF and pushed the IRM in yaw such that the IM was hanging free.
- We actuated in yaw using the picomotor and it moved freely suggesting it had not reached its limit.
- With confidence in the picomotor condition we proceeded to adjust yaw and pitch until the IM became free although the OSEM flags were not at the centres of their cavities.
- Measurements of IM TFs revealed the system was healthy. (IM-V TF was not measured because the SF is locked due to the plastic cover.)
Happily, we can consider the system to be recovered from the jammed-BF-picomotor-earthqueake event.
- Later we moved the IM picomotors in order to move the OSEM flags closer to centers of their cavities.However, this rendered H3 out of range.
- The locked theIRM and the IM and moved H3 into range, but when we released the system we realized V1 had become out of range due to a change in pitch.
- We measured transfer functions with the horizontal OSEMs and they were all good.
- We proceeded with the Trump method to test the pitch stability:
We carried out the procedure from the control room and used the readout from V2 and V3 (V1 out of range) and the 3D-CAD to calculate the change in pitch: -3.9 mrad (consistent with what was measured with an oplev when we disturbed the suspension when we glued the wire).
In the tunnel we carried out the procedure again and used an oplev to measure a change of 33.4 mrad. See the videos.
For the same event we used the V2 and V3 OSEMs to estimate the change in pitch of the IM: 4.1 mrad (consistent with previous measurements).
- Today we inspected the payload visually.
- We didn't find anything wrong.
- Only H2 flag rotated during the Trump procedure. See pictures.
TypeC
- [Miyo] We have to resolve the picomotor range probblem before closing MCE and MCF chambers.
- [Miyo] We will start the suspension commissioning work including the oplev calibration in next week.
Electronics
- [Takahashi] Connected the release sensors to the DGS using the exchange cables in IY.
Control
[Ikeda] Add new RTM block of additional MN and PF OpLevs of Cryo-payload in the current RTM.
- [Ikeda] ITMY is updated with new RTM.
[Ikeda] Now, the old RTM used in O3 is only installed on BS and PR3. Please see Wiki
