 * Discussion
  * Next week, Type-B team will stay in Tokyo to finish remaining tasks
 * Type B Past Week Summary
  * Hirata-san wiped one set each of wires for the BS and RM (additional sets pending).
  * Hirata-san washed remachined locking parts for the IM and screws for jacks.
  * Hirata-san liaised with Ikenoue-san of ATC to get new winch parts designed for the new wire thicknesses. Ikenoue-san provided updated designs for checking.
  * Hirata-san worked on the Inventor 3D assembly of the SR2.
  * The scale for checking the masses of the IM parts arrived.
  * Fabian and Hirata-san assembled the IRM and identified an issue with the Teflon-coated lock screws between the IM and IRM. The screws were slightly too large, and correcting the size with a die caused large flakes of the black coating to come off. (These screws were ordered before the current screw policy was instituted.) Hirata-san will order SDC-coated screws from Misumi and have additional machining done on them.
  * Fabian tracked down the calibration factors for the geophones and generated a calibrated [[attachment:Geophone_Kamioka.png|plot]].
 * 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]]; first 4 expected to be assembled and washed by 8/8)
  * Longer cables for BF->PI and SF->PI ORDERED.
  * 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)
  * 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) - DONE but anomalies found.
  * Pack/ship IM/RM/IRM to Kamioka (Hirata/Fabian).
  * Analyze geophone data (Fabian/Shoda) - data taken by Shoda-san; Fabian to find calibration factors.
  * Remove glue from dummy BS face (Fabian) - partly done.
  * Reglue flags and prisms (Tatsumi, Fabian)
  * 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)
  * 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)
  * Check SR RM machining test progress (Hirata)		  * Put a report here

 * Wide OSEM production and test plan (Akutsu, Aso)
  * Steps
   * Test assemble a few (Akutsu)
   * Noise check (Type-B team)
    * Change the supply current of a satellite amplifier (find the optimal value for the wide OSEM).
    * Calibration
    * Noise measurements
    * Deadline for the noise check: by the end of September
    * Wide OSEM noise should be checked in Kamioka using the digital system. Type-B team will do it when they come to Kamioka.

   * Change the supply current of the satellite amplifiers (talk to AEL: Aso)
 * LVDT test
  * Takahashi and Shoda will discuss about this
  * Points to be clarified: purpose of the test (what kind of information we want to obtain to design the new LVDTs ?)
  * Deadline for the new LVDTs: the end of August.		  * Inertial sensor selection for Type-B update (Fabian)
