 * Type B Past Week Summary
  * Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka:
   * Calculated BS pitch correction ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5630|JGW-T1605630]])
   * Hung dummy optic and set pitch.
   * Prepared RM.
   * Placed vacuum feedthroughs on assembly frame and cleaned D-Sub cables.
   * Decided position of BS rack with Miyakawa-san.
   * Measured maraging rods.
   * Placed safety rails, rearranged floor panels, cleaned new floor panels, and otherwise improved safety.
  * Hirata-san:
   * Made new 3D models of the maraging rods for PRx and SRx
   * Made new collet design for PRx and SRx.
   * Made new IM flag design for PRx and SRx.
   * Washed lots of Type A BF parts and OSEM parts.
   * Measure some BF part dimensions.
   * Pre-assembled parts for BFs.
 * Type B ongoing issues
 * Longer term to-do list
  * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - NEARLY DONE.
   * 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 4/9 ====
 * Mark glued prisms and magnet/standoff assemblies on the SR3. The SR3 needed to be raised in the box by 0.7 mm to make the prisms go on at the right height, which was done using M4 washers under the PEEK feet.
 * Mark glued ferromagnetic disks on the last 5 IM flags. This completes 2 sets, for SR3 and SRM.
 * Mark configured two pico motor drivers ordered by Takahashi-san as SR3-IM and SRM-BF.
 * Enzo and Kozu-kun finished preparing and calibrating the SF and BF for SR3 and almost entirely finished with those for SRM.
 * Hirata-san worked on building two IMs for SR3 and SRM. The SR3 one just needs to have flags attached and to be weighed; the SRM needs another few hours work.
 * Shoda-san worked on the design of the metal SRM, on the LBB ballast mass, and on the plans for testing the BS in bKAGRA Phase 1.
