 * 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).
  * 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) ===
==== Report for week of 1/29 ====
 * Mark made two sets of in-air pico splitter cables (each with a triple for IM and a double for BF) for SR2 and SR3.
 * Fabian, Hirata-san and Kozu-kun worked on cabling and testing the IM pitch/roll/yaw picos, the BF FR and the BF LVDT. The LVDT connections were initially unreliable and Hirata-san had to redo the pins on the coil wires.
 * Fabian installed ballast masses in the BF.
 * Mark worked on schedule.
 * Mark did inventory of the stepper motor drivers (many were not accounted for on the wiki and/or JGWDoc and one is missing) and reserved two for SR3.
