 * Type B Past Week Summary
  * Mark
   * Updated the BS circuit diagram [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=3600|D1503600]]:
    * Added information on the binary IO.
    * Renamed channels to conform to Okutomi-kun's new scheme.
    * Made the ADC/DAC channel assignment consistent and more logical.
    * Updated the stepper motor sections with info about the new driver chassis.
   * Worked on schedule.
   * Updated the installation procedure with lessons learned from the last few weeks.
   * Downloaded Hirata-san's Inventor model of the BS in the tank and starting thinking about installation of the suspension and lower bread board.
   * Mark and Hirata-san worked on collecting parts and tools that will be needed for cabling of the BS next week. (11 special-purpose cables need to be made for the picos/steppers/OSEMs/LVDT on the RM/IRM/IM/BF and, time permitting, 2 more for the SF.)
  * Hirata-san
   * Updated the BS 3D Assembly with the new rods and receptacles.
   * Made 2D drawings of SR2 and SR3 (ongoing).
   * Made SRM 3D assembly (ongoing)
   * Asked for and got quotes for hexagon cable clamps. Takahashi-san ordered the PEEK components. Next week Hirata-san will look for parts that should already be at Kamioka.
   * Washed screws for hexagon cable clamps and shim rings for Fabian.		 === Type B (Mark) ===
==== 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.

==== 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.
