==== 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.

Line 16: Line 8:
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.

==== Plan for week of 11/13 ====

Enzo and Kozu-kun at Mitaka
 * Servos
 * Diagonalization of OL
 * TFs of BF
 * Documentation

Mark and Fabian at Kamioka.
 * Mark attends commissioning workshop at U Toyama.
 * Support BF characterization work.
 * Prepare for mirror gluing.
 * Prepare for IM assembly.

Hirata-san at Mitaka
 * SR procurement.
 * Get BS prism-gluing jigs reworked for use with PR/SR mirror box.
 * Mark and Fabian did a huge cleanup of the SR2 area and prepared a workspace for assembling the IM.
 * Fabian did a stocktake of the screws for the SR.
  * We have all we need for the IM, except one type that can be added after the rest of the IP is assembled.
  * We have most of what we need for the rest of the payload, and Hirata-san has ordered the others.
 * Hirata-san worked on SR procurement:
  * Suspension wire
  * SR additional parts (compensation masses, clamps etc)
  * Regular, SDC and BUMAX screws.
  * Additional machining on the BS sapphire prism jig to allow it to be used on the PR/SR mirror box.
  * LBB blade design.
 * Enzo and Kozu-kun (with help from Fujii-kun) worked on export from SUMCON to Matlab, and on filter design).
Line 50: Line 22:
 * All at Mitaka.
 * SR procurement, planning (Mark, Hirata-san)
 * SR mass budget (Fabian)
 * BS modeling filter design (Enzo, Kozu-kun)
