 * Type B Past Week Summary
  * 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.
 * Type B ongoing issues
  * 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]]		 === Type B (Mark) ===
==== Past week report ====
At Kamioka (Mark, Fabian, Hirata-san, Yoshioka-kun):
 * We reconfigured the top of the assembly frame.
 * We cleaned the assembly frame, blowing dust out of the grooves and wiping all surfaces.
 * We recentered the optic table in the bottom of the frame and adjusted the frame until the top was centered over the optic table. We also recentered the trolleys.
 * We re-installed, centered and leveled the IM.
 * We solved two issues with the new wire clamps:
  * Some holes were not properly threaded - Hirata-san retapped them.
  * Some locating pins were loose - we glued them.
 * We mounted the BS mirror box on the trolley and brought it under the IM.
 * We installed the winch system and the 300 µm wires for the BS.
 * We set up the optical lever.
 * Hirata-san finished the new BF. We moved the old BF out of the cleanbooth and the new one in.
