Past week report
[X-front]
- Dismounted the PI from the top chamber and lifted up the EQ stop to access the F1.
- Adjusted the position of the yoke in F1.
- Removed one of Cu plates from the F1. Rearranged the magnets on the F1 damper.
- Lifted down the EQ stop. Set the top ring onto the frame lock.
- Installed the PI into the top chamber.
- Suspended the F1. The F1 worked freely.
- Calibrated the LVDT for the TF.
- Cabled from the upper small hexagon to the feedthroughs and checked the cable connections.
- Adjusted compression of the blades.
- Released the IP. The behavior of IP showed overload without any ballast rings.
- Found that the IP unit is not for Type-A but for SR.
- Dismounted the PI from the top chamber.
- Calibrated the LVDTs for BF damper.
[X-end]
- Mirapro fixed the corrugate tube more tightly.
Plan for coming weeks
[X-front]
- Swap the IP and reinstall the PI.
- Tune the IP.
- Set the ACCs.
- Set the LVDT coils for the BF damper.
[SR]
- Check the optimal load of new blade prototype on 15th.
[Exchanging of IPs]
- Separate the PI for SRM to the IP and the TF.

OMMT & OSTM (Ohishi)
Past week report
- Have checked the spring constant of the vertical vibration isolation bellows for type-C suspension.
- The constant was about 0.05kgf/mm as required, so I'm asking for a quotation of remaining bellows.
- Have ordered some screws, mechanical parts, and received magnets.
Plan for coming weeks
- As the MCF tank opened, I will check the status of MCo suspension with Kirii-san.
- Continue to order mechanical parts.
