* Type B Past Week Summary * Fabian did inventory of parts/fasteners for dummy BS, RM, IM and IRM - almost all at Mitaka. A handful (picos, pico drivers) will be brought back from Kamioka. * Fabian continued work on Mathematica and Matlab models of the BS and control system. He now gets much better agreement after correcting discrepancies between the parameter sets. * Hirata-san worked on organizing: * Checking Mirapro assembly frame drawings * Ordering missing screws and small items (screws for dummy mass, fine pitch M8 for RM) * Work platforms and clean booth second floor arrangement. * Load gauge adapter and associated parts * Possible fall-back plans for the rods connecting the security structure to the PI. * Design for additional trim masses (existing design had no provision for adding/removing). |
=== Type B (Mark) === ==== Past week report ==== * We brought the SR2 optic into the tunnel and moved it into the good mirror box.

Past week report
- We brought the SR2 optic into the tunnel and moved it into the good mirror box. The spare mirror was moved into the not-so-good mirror box.
- Enzo assembled the SR2 rack and laid all the long cables from the rack into the cleanbooth. (Hayakawa-san can now proceed with the rebuilding of the changing cleanbooth.)
- Mark and Shoda-san took data for calibrating and diagonalizing the OL. (Due to the odd angle of the first steering mirror, the beam pattern is rotated by 62° at the QPD.)
- Enzo found nearly all in-vacuum cables.
- Enzo and Shoda-san got several more loops closed on the BS.
- Mark found three geophone pods and two feedthrough adapters for SR2 (now have 3 FAs but need 4).
- Mark took out S-numbers for anonymous boxes in the SR2 and put yellow stickers supplied by Tomura-san on them.
- Hirata-san worked on SR procurement.
- Hirata-san worked with Mirapro to get the SRM LBB installed in the tank.
