VIS Meeting
Date: 2022/11/11 13:30-13:40
Participants: Takahashi, Uchiyama, Sato, Tanaka, Mitsuhashi, Hirata, Lucia
Summary Report
Type-A
- The F0 in IY had a large drift, but it was recovered with room temperature control.
- Test of the new IP blending with the Geophones and the LVDTs sensor correction in EY.
- Check of the sensor correction performance in EX, IX, and IY.
Type-B
Type-Bp
Type-C
- During the adjustment of the OSTM suspension, two magnets (H2, H3) on the mirror dropped off. We made the in-situ gluing jig for the magnets and glued them successfully.
- Finally the OSTM was aligned not using the picomotor but rotating the suspension frame in yaw.
