 * 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.
   * 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) ===
==== Report for week of 9/10 ====
 * We finish the invacuum and in air cabling for SR2, but the in-vacuum cables for Geophones and F0 Yaw stepper motor are just temporary and will be replaced later once the suspension is inside the tank.
 * We checked all the motors, like:
       ** the IM picos, BF picos.
 * We checked the BF Stepper (Fishing rod), SF Stepper (SF Fishing rod), F0 Stepper (F0 Fishing rod).
 * We debugged an issue with the IP LVDTs and discovered it was a broken interface card D1402829 in the LVDT driver. We made up a working chassis with the original two driver cards, so we didn't have to reset all the phases and gains.
 * We reset the IP FRs to midrange.
 * We added a basic set of arc weights and recentered the IP. We then adjusted the verticality of the security structure.
 * We relocked the IP temporarily, unlocked the SF/... section and aligned the IM OSEMs.
 * We powered down the BS, SR3 and SR2 electronics in preparation for the power outage.

 * We did more in-vacuum and in-air cabling for SR2 and got nearly everything connected.
 * We debugged the IM OSEMs and fixed two broken in-vacuum cables and some mislabeled in-air cables.
