 * 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) ===
==== Report for week of 3/19 ====
 * Fujii-kun successfully assembled and tested a geophone pod (klogs 4492, 4508).
 * Hirata-san set up the dummy BS to soak off the sapphire prisms. (In process)
 * Shoda-san, Hirata-san and Enzo finished the assembly of 12 OSEMs. We still need to measure the maximum output (In process)
 * We will send the OSEMs to Kamioka today.
 * Enzo made 2 In-air picomotor cable.
