Line 5: Line 5:
 * Hirata-san produced a near-final Inventor assembly of the BS on the assembly frame, for use in writing the assembly procedure.
  * Includes assembly frame modifications suggested by Mirapro, including feet, wheels, lifting eyes, thicker crossbars under BF, IM etc.
  * Includes final rail system except for interface plate to mirror box.
  * Includes full PI with ballast masses.
  * Includes cable clamps.
  * Includes correct versions of BF and SF.
  * Includes new BF pushrod parts to work around different placement of blade screws in new version of BF.
  * Includes cleanbag support bars.
  * Includes key parts of mirror box (enough to check for interference) - needs more work.
  * Does not include various invisible duplicate assemblies that had been present due to cut and paste.
  * After a few more improvements, the new assembly will be sent back to Mirapro.
 * Got status from Miyakawa-san on electronics - there should be enough of the boxes AEL is supplying.
 * Cleanbag design was finalized; Aso-san is ordering: [[attachment:160419-ﾁｬﾝﾊﾞｰｶﾊﾞｰⅡ型.pdf]]
 * Quote for flags and prisms was received, but expensive - may drop rigid flag design.
 * The mirror box will require only very minor modifications for flags and prisms - Tatsumi-san will arrange immediately.
 * Fabian worked on understanding Sekiguchi-san's control design to help decide optimum wire thickness.
 * Mark worked on install procedure and schedule.
 * Takahashi-san enquired with NIKHEF about oscillator cards for LVDT chassis - lead time would be 3-4 months.
 * 		 * Type B Past Week Summary
  * Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka:
   * Calculated BS pitch correction ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5630|JGW-T1605630]])
   * Hung dummy optic and set pitch.
   * Prepared RM.
   * Placed vacuum feedthroughs on assembly frame and cleaned D-Sub cables.
   * Decided position of BS rack with Miyakawa-san.
   * Measured maraging rods.
  * Hirata-san made a 3D assembly model for SR2 and added the optical design.
  * Hirata-san worked with Uchiyama-san to solve the 90° rotation problem. It turns out the "box" part with the pistons can be rotated, so we can build the SR2 according to the original design.
  * Hirata-san investigated the puzzle of the BF-IM maraging rods, where the 2D drawings and 3D CAD do not agree. Fortunately the actual parts seem to agree with the 3D CAD.
  * Hirata-san washed 3 OSEMs (last of initial 10 for BS) and parts for two BFs (for Type A). He moved the BF parts into the clean room and will assemble them with ATC staff from next Wednesday 9/7.
 * Type B ongoing issues
  * Longer cables for BF->PI and SF->PI - RECEIVED
 * Longer term to-do list
  * Decide position of BS rack - DONE
  * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - NEARLY DONE.
  * 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)
  * 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)
