Participants:
Progress report
Type-A (Takahashi)
- Pre-isolator: The top filter was mounted onto the IP. The shaft screw of motor was not matching to the slider for fishing rod. New shafts were ordered.
- EQ stop, release sensor, dummy payload: Production is on going.
- BF damper: Open bidding is on 9th November.
- Maraging wire: Hirata-san made 2D drawings. The wires will be ordered soon.
- Installation: Making assembly drawings for the installation procedure document. The review is held on 4th November.
Type B (Mark)
- Type B Past Week Summary
- Fabian, Mark and Liu-kun did BS installation at Kamioka:
- Debugged the issue with the BF keystone being tilted enough to cause rubbing on the yoke for the magnets. It was solved by moving the yoke ≈1 mm taking advantage of the oversized holes.
- Measured the height of the payload as a function of trim mass. The BF spring seems to have a slightly lower load capacity and a rather higher spring constant than when it was remeasured by Hirata-san.
- Removed IM trim mass to set the average height of the keystone to the CAD value.
- Moved IM trim mass around to set the pitch of the dummy BS.
- Hirata-san
- TBD.
