 * Type B Past Week Summary
  * Mark did a Type B schedule presentation at the Extended Chiefs Meeting. It was decided to order a second assembly frame so that the BS/SR2/SR3/SRM installations can overlap more.
  * Mark and Hirata-san helped Mirapro construct the assembly frame ([[https://goo.gl/photos/tVGoebw7FTRMAYB2A|photos]]).
  * Mark and Hirata-san took the jacks and adapter plates off the frame, and cleaned them to remove as much of the original grease as possible. Takahashi-san has offered to re-grease them with vacuum grease.
  * Mark and Hirata-san wiped down the assembly frame and put the clean bag on it.
  * Saito-san, Ohishi-san and several people from Mirapro adjusted the position of the BS chamber.
  * Mark plugged the geophones back into the PR2 rack and checked that the repaired cable was working.
  * Fabian did more pre-assembly of the RM/IM/IRM.
  * Takahashi-san ordered 10 mm diameter x 10 mm long magnets for the IM flags.
  * Mark inspected the SR2 section of the clean booth to see where SR2 assembly could be done. The slot in the ceiling for the crane runs in the ±X direction (at right angles to that for the BS), and there are suitable space on both the +X and the -X sides of the SR2 tank.
  * Hasegawa-san (of Hirose-san's lab) took delivery of the cup for removing the prisms on the dummy BS. It fits well.
  * Tatsumi-san ordered [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5357|modifications]] to the BS gluing jig to make it easier to remove the pieces holding the flags after the flags are attached. The parts are expected Fri 7/8. He also ordered more EP30, but this won't arrive until the week of 7/18.
 * 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.

==== Vacation Info ====
 * Mark 12/22-1/3
 * Enzo TBD, probably 12/22-1/3
 * Fabian 12/22-1/5
 * Hirata-san 12/21-22 (conference)
