  * Akutsu-san provided a set of cleanroom gear (shoes only slightly too tight!) for use by Mark this week. And Sakamoto-san sent another set from Kamioka to Kashiwa.
  * Fabian did a fit test of the winches onto the IM.
  * The RM, IM and IRM were weighed, and wrapped/packed for shipment to Kamioka.
  * Mark made a checklist of all the parts of the BS mirror box and gluing jig, to help with collecting the parts from Kashiwa.
  * Fabian designed an extra 600 g of trim masses for the IM and Hirata-san made drawings and ordered them. The design allows for the masses to be added to the IM even after it has been placed in the assembly frame and the dummy optic and RM have been hung, so it should not delay work.
  * Mark worked on the schedule, making the next few weeks more realistic and incorporating the new plan for the SR RMs (the test will be used for SR2 but two more will be made from scratch next financial year).
  * Fabian worked on the payload assembly procedure.
  * Hirata-san washed 7 OSEMs for Akutsu-san, and various other parts for Yamamoto-san of ICRR.
  * Hirata-san removed the remaining glue from the BS primary and secondary prisms, as well as the prisms removed from the PR hanging test mirror. (The small sapphire prisms for the PR were not intended to be reused and one had already broken at Kashiwa, but the metal PR secondaries can and will be used again.)
 
 * Type B ongoing issues
  * OSEMs
   * Akutsu-san is working to get wide-mouth OSEMs ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1853|2 assembled]]; another few were assembled and a batch of 7 were washed.
  * 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]]
 * To-do list during Mark's vacation
  * Weigh IM/RM/IRM (Fabian, Hirata) - NEW TRIM MASS ORDERED.
  * Pack/ship IM/RM/IRM to Kamioka (Hirata/Fabian) - READY TO SHIP.
  * Analyze geophone data (Fabian/Shoda) - DONE.
  * Remove glue from dummy BS face (Fabian) - MOSTLY DONE.
  * Reglue flags and prisms (Tatsumi, Fabian) - from Friday 8/5.
  * Clean wire for BS and RM (Hirata) - DONE
  * Get new winch parts for new wire diameters - design received from Ikenoue-san
  * Do fit/function test of winches (Fabian/Hirata) - DONE
  * Ship winches to Kamioka (Hirata/Fabian)
  * Work on BS simulation (Fabian)
  * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - ONGOING.
  * 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)
  * Mark
   * Updated the BS circuit diagram [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=3600|D1503600]]:
    * Added information on the binary IO.
    * Renamed channels to conform to Okutomi-kun's new scheme.
    * Made the ADC/DAC channel assignment consistent and more logical.
    * Updated the stepper motor sections with info about the new driver chassis.
   * Worked on schedule.
   * Updated the installation procedure with lessons learned from the last few weeks.
   * Downloaded Hirata-san's Inventor model of the BS in the tank and starting thinking about installation of the suspension and lower bread board.
   * Mark and Hirata-san worked on collecting parts and tools that will be needed for cabling of the BS next week. (11 special-purpose cables need to be made for the picos/steppers/OSEMs/LVDT on the RM/IRM/IM/BF and, time permitting, 2 more for the SF.)
  * Hirata-san
   * Updated the BS 3D Assembly with the new rods and receptacles.
   * Made 2D drawings of SR2 and SR3 (ongoing).
   * Made SRM 3D assembly (ongoing)
   * Asked for and got quotes for hexagon cable clamps. Takahashi-san ordered the PEEK components. Next week Hirata-san will look for parts that should already be at Kamioka.
   * Washed screws for hexagon cable clamps and shim rings for Fabian.
