  * 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
  * Wires
   * Need to decide RM wire thickness and order BS and RM wires. Lead time is a few days from Nilaco.
  * 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 for Fabian/Hirata-san during Mark's vacation
   * 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)		   * Fabian, Mark and Liu-kun did BS installation at Kamioka:
   * Built up the security structure to the ring below the BF.
   * Adjusted the crossbeams below the BF and installed the jacks and pushrods to support the BF.
   * Craned in the BF.
   * Hung the top plate of the IRM.
   * Practiced hooking the BF-IM maraging rod (by lowering the BF with the jacks) - success. Need to redo with hexagon cable clamp.
   * Took TFs from L, P and actuation at the RM to all DOFs at the BS.
  * Hirata-san:
   * Made 3D models of (revised) stub flag gluing jigs.
   * (For other groups)
    * Assembled two BFs.
    * Made drawings of PRM inner frame.
  * Mark checked lots of drawings by Hirata-san.
  * Mark worked on schedule.
  * Mark added the DIO card to a draft of the BS electronics diagram, D1503600. At first it appeared that the pinouts of the LPCD DIO connectors were completely incompatible with the DIO card cables, but it turns out (according to Miyakawa) that the LPCD chassis has a secret interface board (JGW-D1504332) not shown in the chassis drawing which should make everything work.
 * Longer term to-do list
  * Do Inventor assembly for SRx in chamber and on assembly frame (Hirata) - SR2/SR3 DONE, SRM ongoing.
   * 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) - TM/IM/BF level DONE
  * Do 2D drawings of SR2 parts (Hirata)
