 * 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)		 === Type B (Mark) ===
==== Past week report ====
At Kamioka (Mark, Fabian, Hirata-san, Yoshioka-kun):
 * We reconfigured the top of the assembly frame.
 * We cleaned the assembly frame, blowing dust out of the grooves and wiping all surfaces.
 * We recentered the optic table in the bottom of the frame and adjusted the frame until the top was centered over the optic table. We also recentered the trolleys.
 * We re-installed, centered and leveled the IM.
 * We solved two issues with the new wire clamps:
  * Some holes were not properly threaded - Hirata-san retapped them.
  * Some locating pins were loose - we glued them.
 * We mounted the BS mirror box on the trolley and brought it under the IM.
 * We installed the winch system and the 300 µm wires for the BS.
 * We set up the optical lever.
 * Hirata-san finished the new BF. We moved the old BF out of the cleanbooth and the new one in.
