 * Type B Past Week Summary, weeks of 9/19 and 9/26
  * 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.
 * 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
  * Lower breadboard installation to be incorporated into the procedure document.
  * Work on BS simulation (Fabian)
  * Do BS Simulink model (Mark, Kokeyama) - TM/IM/BF level DONE
  * 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) ===

 * We checked the polarity of the IP LVDTs and flipped coil connections to get the standard arrangement.
 * We debugged an issue where one of the LVDT actuators had half the magnets in backwards resulting in no force.
 * We calibrated all the PI LVDTs.
 * We set the SF damper ring gap.
 * We prepped the suspension for craning, moved it into the tank and hooked the LBB damper ring rods.
 * Type A merged the SRM F0 with the correct IP, and we moved it out of the way (to the second floor behind the SRM tank).
 * We installed more cable clamps on the SR2 PI.
