Past week report
[Y-end]
- Calibrated the LVDTs for BF damper.
- Started the evacuation of EYV chamber. The IP is touching the stopper.
[X-end]
- Prepared for the payload extraction. Fixed the BF and pushed down the keystone of TF.
- Replaced the yaw FR.
[X-arm measurement]
- Measurement campaign with X-arm was conducted.
- Some stages were excited and then the couplings to the TML etc were measured.
- Excited dofs were: TML / IML / MNL / IPL / (partly BFL) / BF-GAS / IMV / TMP
- The purpose was to get the followings:
- Vibration isolation performance (GND2TML)
- force transfer functions of TML2TML, IML2TML, MNL2TML
- couplings of V2L, P2L (somehow I forgot to measure Y2L coupling)
- Now analysis is ongoing.
force TFs are in klog#7573
Plan for coming weeks
- Replacement of the yaw FR in X-front on 17-18.
