 * Type B Past Week Summary
  * Fabian prepared a work space in the ATC cleanroom and moved in nearly all the parts for the dummy BS, RM, IM and IRM.
  * Fabian finally got perfect agreement between the Mathematica and Matlab models of the BS. (The wire thicknesses had in µm instead of mm, leading to some modes off by 1E3.)
  * Hirata-san remeasured the BF for the BS. He noted that the cap went on and came off easily (unlike some other filters).
  * Hirata-san worked on final details of the Mirapro order for the assembly frame.
  * Hirata-san and Takahashi-san washed a large batch of parts.
  * Tatsumi-san will glue flags, sapphire primary prisms and metal secondary prisms to the dummy BS some time in the week of 6/8. Fabian and possibly Mark and/or Hirata-san will travel to KEK to help and observe.
  * Mark worked more on [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235|E1504235 BS Assembly Procedure]] ([[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|Draft on OneDrive]])		 === 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 built two IMs for SR3 and SRM, and tested the pitch and roll adjustment by running each mass to both limits of its range with the pico driver.
 * Shoda-san worked on the design of the metal SRM.

==== Plan for week of 4/16 ====
 * Shoda-san at Mitaka
 * Tanioka-san at Kamioka Tue-Thu
 * Others at Kamioka full week

 * Move SF and BF for SRM out of the way.
 * Check results of gluing.
 * Build 1xRM
 * Start SR3 Hang
  * Reset assembly frame crossbars to correct heights.
  * Center the optical table.
  * Align the assembly frame vertically.
