 * Type B Past Week Summary
  * Mark, Fabian and Hirata-san cleaned glue off the dummy BS, attached Akutsu-san's new SS mirror plates, reglued the flags and prisms, and removed the gluing hardware, so the dummy BS is ready for shipping. Tatsumi-san's refinements to the tooling (especially the new flag holders) worked very smoothly. We were more generous with the glue and much more careful with the alignment of the prisms to the barrel, both during rehearsal and the final gluing.
  * Mark wrote up the gluing procedure as a new document [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5505| E1605505]]. (The original plan was to do an addendum to Tatsumi-san's PR gluing procedure JGW-E1504248, but there was too much material.)
  * Hirata-san organized with Takahashi-san to get the BS payload masses shipped to Kamioka. They will go in an air-ride truck on Wed 8/17 together with a load of Type A stuff, and will arrive early on Thu 8/17.
  * Hirata-san measured another standard filter.
  * Fabian worked on the payload assembly procedure.
  * Komori-kun, Kuwahara-kun and Akutsu-san calibrated an initial batch of 7 wide-mouthed OSEMs. They will be shipped to Kamioka on Friday.
 
 * Type B ongoing issues
  * OSEMs
   * First batch of 7 ready for shipping.
  * Longer cables for BF->PI and SF->PI.
   * Connectors RECEIVED, cables being made.
  * Lower breadboard stuff
   * Installation to be incorporated into the procedure document. Mark/Takahashi to discuss.
  * Documents
   * 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]]

  * 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 7/17 ====
 * We checked the polarity of the IP LVDTs and flipped coil connections to get the standard arrangement.
 * We debugged an issue where one of the LVDT actuators had half the magnets in backwards resulting in no force.
 * We calibrated all the PI LVDTs.
 * We set the SF damper ring gap.
 * We prepped the suspension for craning, moved it into the tank and hooked the LBB damper ring rods.
 * Type A merged the SRM F0 with the correct IP, and we moved it out of the way (to the second floor behind the SRM tank).
 * We installed more cable clamps on the SR2 PI.

==== Plan for week of 7/23 ====
 * Mark, Enzo, Fabian, Kozu-kun, Terrence, Panwei at Kamioka Mon-Fri.
 * Hirata-san at Kamioka Mon-Thu.
 * Mirapro moves assembly frame ≈7/25 (Wed).

===== SR3 =====
 * Unlock suspension.
 * Rearrange cables.
 * Test.
===== SR2 =====
 * Finish PI prep.
 * Crane into AF, suspend.
 * Start cable routing.
===== SRM =====
 * Prepare to assemble SRM metal mass (most parts due Wed 7/25).
 * Help Mirapro with AF move.
 * Start rebuild of top filter of PI #2.
