  * There were multiple issues with the dummy BS flag/prism gluing [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1830 |klog]]. The sapphire prisms will need to be removed and reapplied. Hirose-san is going to organize this. He wants to try the cup that had been made for the PR2 on the actual PR2 and then see if a new cup is needed for the BS (considering the different radius).
  * Hirata-san added the optical layout information to the BS Inventor assembly. He requested tank information from Mirapro so he can continue to do SR2/3/M.
  * Fabian finished the IM assembly and started on the IRM and RM. Some of the IRM panels had been improperly wrapped and really should be re-cleaned. The MPC (multi-purpose cube) on the RM will need some rework.
  * Mark scheduled a review for Thursday 6/16.
  * 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).
  * 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.
Line 11: Line 19:
  * Wires
   * Need to decide RM wire thickness and order BS and RM wires. Lead time is a few days from Nilaco.
  * OSEMs
  * Feedthrough Adapters
   * Need large quantity of male and female D-Sub 9, IDC ribbon connectors - Takahashi-san is getting a quote.
  * Can we make SR wire breakers bigger?
   * Fukushima-san will start on machining test soon (as of 5/27).
  * Not enough crane height problem (Hirata, Saito) - no action since last week
  * Installation stuff
   * Crane scale - quote received
   * Work platforms - RECEIVED
  * Ballast masses for payload
   * Initial batch received - ordered extra smaller ones to allow for adjustments.
  * Lower breadboard stuff
   * Installation to be incorporated into the procedure document. Mark/Takahashi to discuss.
   * Breadboard springs (in manufacture, expected end of July)
   * Nail-head parts: quote from Mirapro received, not urgent, will be combined with assembly frame order.
  * Clean bag - RECEIVED.
  * Documents
   * 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]]
 * 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)
