 * Type B Past Week Summary
  * Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka:
   * Hung RM.
   * Did permanent routing of RM OSEM cables to IM.
   * Did temporary routing of RM OSEM in-vacuum cables to flange (4 channels).
   * Did semi-permanent routing of all OSEM external cables to satellite amps (10 channels)
   * Did temporary routing of RM OSEMs to PR2 rack (4 channels).
   * Took data with geophones connected but immobilized and then stored geophones in boxes.
   * Tested signals from first satellite amp getting to digital system.
   * Weighed mirror box.
   * Did fit check of flag holders for stub flags. Very minor adjustments will be needed.
   * Covered everything in preparation for modifications to clean booth roof (9/20-21).
  * Hirata-san:
   * Finished 3D CAD of SR2 and SR3 in tanks, with optical layout included.
   * Started 3D CAD for SRM.
   * Checked flag design.
   * Assembled a bottom filter (ongoing).
   * Cleaned maraging rods.
 * Type B ongoing issues
 * Longer term to-do list
  * Do Inventor assembly for SRx in chamber and on assembly frame (Hirata) - SR2/SR3 DONE, SRM ongoing.
   * Part "disk security" top has to be modified - screw positions do not match.
  * Write more of payload assembly procedure (Fabian) - ONGOING
  * Write more of BS Assembly Procedure [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]], [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|E1504235 draft]] (Mark) - ONGOING
  * Lower breadboard installation to be incorporated into the procedure document.
  * Work on BS simulation (Fabian)
  * Do BS Simulink model (Mark, Kokeyama)
  * Do 2D drawings of SR2 parts (Hirata)
  * Redesign SRx IM wire clamps for larger prisms, remachined RMs
  * Order SRM/PRM parts (Hirata/Shoda)
  * Order SRx fasteners (Hirata)		 === Type B (Mark) ===
==== 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.

==== Plan for week of 12/25 ====
 * Power outage 12/25.
 * Mark, Enzo, Fabian vacation
 * Shoda-san, Kozu-kun, Hirata-san at Kamioka - Hirata-san from Tue, others TBD.
 * Recover after power outage.
 * Create SR2 real-time model.
 * Install new jack receptacles (in SR3 area, second floor) on load gauge adapter (SR2 area, second floor). (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.

==== Plan for week of 1/9 ====
 * Mark, Fabian, Enzo, Shoda-san at Kamioka Tue-Fri.
 * Hang SR and RM.

==== Vacation Info ====
 * Enzo 1/30-2/19
