  * 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)
  * Fabian, Mark and Liu-kun did BS installation at Kamioka:
   * Connected the DIO card to the LPCD. (Simulink model changes will be needed to make use of it.)
   * Took TF data from the TM-H1 coil output to the voltage and current monitors and found that the response was approximately flat, meaning that meaningful TFs can be taken of the RM/BS stage with no DIO.
   * Used the 90° prism and the optical lever to set the pitch of the RM to match the dummy BS.
   * Removed the RM trolley and added the bottom section of the security structure.
   * Lifted the IM/RM/BS with the load gauge adapter and load gauge and measured its mass.
  * Hirata-san:
   * Modified drawing of maraging rods for BS [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5706| D1605706]]
   * Made 3D models of stub flag gluing jigs.
   * Made 3D models and 2D drawing of BS BF-IM hexagon cable clamp assembly and cone parts. [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5734| D1605734]]
   * Washed parts and screws.
   * (For Type A) Assembled and adjusted blades of BF #9.
  * Mark checked lots of drawings by Hirata-san.
  * Mark worked on schedule but only succeeded in completely garbling the Type B section of the VIS schedule on the server.
 * 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
