   * A hole in a picomotor holder was too small. ATC staff solved this isue quickly and Hirata-san cleaned the piece.
   * Some ballast discs for the dummy optic were dirty (seen by visual inspection). Hirata-san cleaned them.
   * Some arrows were cleaned from the mirrors for the dummy optic.
  * Hirata-san worked on checking Mirapro's assembly frame design - some minor issues with rail system found.
  * Hirata-san measured another filter.
  * Hirata-san washed a large batch of parts.
  * Mark worked on solutions to allow a [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/VIS/TypeB/dummyBS|larger mirror on dummy BS]]
  * Mark worked on list of items for purchase in FY2016.
  * Mark worked more on [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235|E1504235 BS Assembly Procedure]] ([[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|Draft on OneDrive]])		   * 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

  * 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.
