| ==== 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. |
==== Past week report ==== * Mark created screens and a macro.txt file for the SR2 and linked to them from the VIS screen. * Enzo and Mark did a new overview screen for the BS. * Enzo added DIO cards to the rack and connected them to the coil drivers. * Fabian and Kozu-kun finished assembling the IM and tested the picos over their full range. * Mark and Hirata-san configured and aligned the assembly frame and optical table and craned in the IM ring. * Hirata-san noticed some oxidization on several of the L-brackets that will hold the IM horizontally, and we should get them cleaned or machined, but we can probably continue with hanging the system in the meantime. |

| 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. |

(Hirata-san) * Weigh IM (per Fabian's note in the paper log). * Remove L-brackets from bars on IM ring - send for cleaning/remachining. * Setup OL for checking pitch of SR. * Wipe/blow dust off SR2 frame. * Crane IM into frame. |
