 * Type B Past Week Summary
  * Fabian took photos of the cleanroom in the ATC to help decide whether it is a good place to assemble PIs for Type A/B.
  * Hirata-san ordered and received wire for the BS and RM (will be cleaned 7/19).
  * Hirata-san received remachined locking parts for the IM (will be cleaned 7/19).
  * Hirata-san ordered additional Misumi parts to be used with the IM locking parts.
  * Fabian and Hirata-san weighed the masses that they've been constructing in the cleanroom and found a 600 g discrepancy from the Inventor (too light) for the IM.
  * Hirata-san ordered a medium-capacity scale to weigh the masses of the individual parts more precisely.
  * Hirose-san and his team successfully removed the misglued prisms from the dummy BS.
  * Fabian travelled to Kashiwa and removed most of the glue from the face of the dummy BS (where the flags had been). There is still some adhesive remaining on both the face and barrel, which will require more work and a second trip.
  * Shoda-san took a suitable segment of geophone noise data for analysis. Fabian will track down the calibration factors.
 * Type B ongoing issues
  * OSEMs
   * Akutsu-san is working to get wide-mouth OSEMs
  * Longer cables for BF->PI and SF->PI.
   * Connectors RECEIVED, cables being made.
  * SR machining test ongoing.
  * Lower breadboard stuff
   * Installation to be incorporated into the procedure document. Mark/Takahashi to discuss.
   * Breadboard springs (in manufacture, expected end of July)
   * Nail-head parts - RECEIVED.
  * 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]]
 * To-do list during Mark's vacation
  * Apply grease to jacks for assembly frame (Takahashi)
  * Finish assembly of BS IM, RM and IRM (Fabian).
  * Weigh IM/RM/IRM (Fabian, Hirata)
  * Pack/ship IM/RM/IRM to Kamioka (Hirata/Fabian).
  * Analyze geophone data (Mark, Shoda)
  * Remove glue from dummy BS face (Fabian)
  * Remove prism from dummy BS (Hirose, Fabian?)
  * Reglue flags and prisms (Tatsumi, Fabian)
  * Buy wire for BS and RM (Hirata)
  * Clean wire for BS and RM (Hirata)
  * Do fit/function test of winches (Fabian/Hirata)
  * Ship winches to Kamioka (Hirata/Fabian)
  * Work on BS simulation (Fabian)
  * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata)
  * Apply vacuum grease to jacks for BS assembly frame (Takahashi)
  * Write more of payload assembly procedure (Fabian)
  * Write more of main assembly procedure (Mark)
 * Longer term to-do list
  * 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)
  * Check SR RM machining test progress (Hirata)		 === Type B (Mark) ===
==== Past week report ====

 * We brought the SR2 optic into the tunnel and moved it into the good mirror box. The spare mirror was moved into the not-so-good mirror box.
 * Enzo assembled the SR2 rack and laid all the long cables from the rack into the cleanbooth. (Hayakawa-san can now proceed with the rebuilding of the changing cleanbooth.)
 * Mark and Shoda-san took data for calibrating and diagonalizing the OL. (Due to the odd angle of the first steering mirror, the beam pattern is rotated by 62° at the QPD.)
 * Enzo found nearly all in-vacuum cables.
 * Enzo and Shoda-san got several more loops closed on the BS.
 * Mark found three geophone pods and two feedthrough adapters for SR2 (now have 3 FAs but need 4).
 * Mark took out S-numbers for anonymous boxes in the SR2 and put yellow stickers supplied by Tomura-san on them.
 * Hirata-san worked on SR procurement.
 * Hirata-san worked with Mirapro to get the SRM LBB installed in the tank.
 
==== Plan for week of 12/4 ====
 * Mark at Kamioka.
 * Fabian at f2f satellite meeting Mon, then Kamioka.
 * Enzo at f2f then Mitaka.
 * Hirata-san at Kamioka Mon-Thu, Mitaka Fri.
 * Kozu-kun Thu only.
 * Mirror gluing.
 * IM assembly and pico test.

==== Plan for week of 12/11
 * Mark, Fabian, Enzo, Hirata-san, Shoda-san at Kamioka.
 * Kozu-kun Mon-Thu only.
 * Assembly frame alignment and optical table centering.
 * Move trolley system from SR3.
 * OL setup.

==== Plan for week of 12/18 ====
 * Shoda-san vacation
 * Mark, Fabian, Enzo, Kozu-kun at Kamioka Mon-Wed.
