 * Type B Past Week Summary
  * Fabian, Mark and Liu-kun did BS installation at Kamioka:
   * Built up the security structure to the ring below the BF.
   * Adjusted the crossbeams below the BF and installed the jacks and pushrods to support the BF.
   * Craned in the BF.
   * Took TFs from L and P actuation at the RM to all DOFs at the BS. (Y actuation still to be done.)
  * Hirata-san:
   * Made 3D models of (revised) stub flag gluing jigs.
   * (For other groups)
    * Assembled two BFs.
    * Made drawings of PRM inner frame.
  * Mark checked lots of drawings by Hirata-san.
  * Mark worked on schedule.
  * Mark added the DIO card to a draft of the BS electronics diagram, D1503600. At first it appeared that the pinouts of the LPCD DIO connectors were completely incompatible with the DIO card cables, but it turns out (according to Miyakawa) that the LPCD chassis has a secret interface board (JGW-D1504332) not shown in the chassis drawing which makes everything work.
 * 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 4/9 ====
 * We packed away the SRM SF and BF.
 * After several failed attempts with one secondary prism, Mark finished the SR3 prism/magnet gluing.
 * Tanioka-kun built two IRMs (less OSEMs).
 * Enzo built an RM.
 * Kozu-kun and Enzo calibrated one set of 6 IM OSEMs for SR3. (6 OSEMs for SRM remain to be done.)
 * Hirata-san aligned the assembly frame, installed the interface bars and IM ring, and installed the IM.
 * Eleonora and Izumi-san revisited the BS length to tilt coupling, which had degraded, and got it working again.
