[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. |

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.
