| * Put a report here | * Type-Bp modification * Saito-san made the 1st version of the 2D drawing. Though we still have small modification, we can start cost estimate. * F7 LVDT * Virgo LVDT test is ongoing. The measured calibration factor and noise level is worse than expected. More tuning is required. * Installation related issues * BF weight is lighter than the 3D model. (CAD: 50 kg, measured: 45 kg.) Shoda has not been able to find any reason yet. Further investigation will be done in next week. * Mirapro sent us the design of the optical bench installation jigs. We sent them some request for the update. * The design of the assembly frame is almost fixed. * Simulation and others * None * '''A/I''' * Investigate the BF weight inconsistency (Shoda) * Some 2D drawings not related to the modification (additional masses, OB wire hook, OB wires,,,) (Hirata) * Assembly drawing (Shoda) * Optical bench additional parts design * Organize the mirror preparation |
Agenda/Minutes of the VIS Meeting on 2016/8/19

Progress report
Type-A (Takahashi)
- Task list was updated.
- No type-A meeting in this week.
- EQ stop, release sensor, dummy payload: The specification document and drawings were fixed. The bidding was announced on the 17th.
- Installation procedure: The review was held on the 10th.
- Standard filters: Cheking of 6 sets were finished and shipped to Kamioka.
- BF damper: LVDT sample is under testing. The measured noise is too large (10^-6 m/rtHz).
Type-B (Mark)
- Put a report here
Type-Bp (Shoda)
- Type-Bp modification
- Saito-san made the 1st version of the 2D drawing. Though we still have small modification, we can start cost estimate.
- F7 LVDT
