==== Past two weeks report ==== Kamioka (Mark, Enzo, Kozu-kun): * Supported IA team. * Replaced LPCDs for IM OSEMs with HPCDs for increased pitch/yaw range. * Re-zeroed OL after significant change of beam position during IA. * Re-laid-out OL to improve focus of lens to LEN QPD. * Offloaded the pitch/yaw actuation at the IM OSEMs using the IM pitch/yaw picos. * Enzo worked on design of control loops using the OL. * Kozu-kun worked on diagonalizing the OL. |

Mitaka (Fabian, Hirata-san): * Fabian did mechanical design: * F0 FR * Cable clamps for the SR IP base. * New SR recoil ballast masses. * LBB ballast. * Update of BS 3D CAD with the as-built ballast. * Hirata-san * made and updated inventory list for SR. * made order list and asked some quotes. * Ordered some parts. * Talked with mirapro about SRM optical bench. * Made some drawings for SR preparation. |
* 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. ==== Plan for week of 12/4 ==== * Mark at Kamioka. * Fabian at f2f satellite meeting Mon, then Kamioka. * Enzo at f2f then Mitaka. * Hirata-san at Kamioka Mon-Thu, Mitaka Fri. * Kozu-kun Thu only. * Mirror gluing. * IM assembly and pico test. |

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.
