 * Type B Past Week Summary
  * Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka:
   * Hung RM.
   * Did permanent routing of RM OSEM cables to IM.
   * Did temporary routing of RM OSEM in-vacuum cables to flange (4 channels).
   * Did semi-permanent routing of all OSEM external cables to satellite amps (10 channels)
   * Did temporary routing of RM OSEMs to PR2 rack (4 channels).
   * Took data with geophones connected but immobilized and then stored geophones in boxes.
   * Tested signals from first satellite amp getting to digital system.
   * Weighed mirror box.
   * Did fit check of flag holders for stub flags. Very minor adjustments will be needed.
   * Covered everything in preparation for modifications to clean booth roof (9/20-21).
  * Hirata-san:
   * Finished 3D CAD of SR2 and SR3 in tanks, with optical layout included.
   * Started 3D CAD for SRM.
   * Checked flag design.
   * Assembled a bottom filter (ongoing).
   * Cleaned maraging rods.
 * Type B ongoing issues
 * 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)
  * 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 6/11 ====
 * Enzo redid the SR3 BIO connections to match the now-working BS setup. He also fixed PR2, which had a similar problem.
 * Enzo replaced LPCDs with HPCDs in the SR3.
 * Hirata-san installed the cable clamps and Cu segments on the SF cap.
 * Hirata-san and Kozu-kun continued tuning the filter in PI #3. Unfortunately it seems to be rather weaker than expected, and we have not found a compression setting that gives a good frequency. We may have to use tricks like reducing the number of Cu segments on the SF (or using Al ones) to save weight.
 * Mark, Enzo and Terrence suspended the BF/... section from the SF, and got it aligned for TFs.

 * Cable, test SF LVDT and FR.
 * Add calculated ballast to SF.
 * Finish tuning F0 #3 for SR3.
 * Park F0 #1 (for SR2) in top of SR3 assembly frame.
 * Move F0 #3 behind SR3.
 * Move F0 #1 to "factory" area (in front of SRM) and start rebuild.
