  * Fabian finished dummy BS assembly.
  * Mark and Tatsumi-san glued magnets into both types of BS optic flags, and discs into BS IM flags. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1815 |klog]] Two optic flags had to be redone because the magnets moved while the glue was drying. Hirata-san helped remove the magnets with acetone in the ultrasonic cleaner. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1818|klog]]
  * Tatsumi-san, Fabian and Mark took the dummy BS to Kashiwa and glued the flags and prisms. We will check status on Mon 6/13.
  * Hirata-san measured another filter.
  * Hirata-san washed a batch of parts.
  * Hirata-san worked on work platforms for the installation.
  * Hirata-san looked for a crane scale for use at the site. (We decided the 500 kg version of the one used at TAMA.)
  * Hirata-san worked on making some guide parts for the PI installation (Misumi parts with minor additional machining from ATC).
  * We finalized a design for simple SS mirror parts for the dummy BS with Akutsu-san. They will be made by ATC.
  * Mark worked on list of items for purchase in FY2016 and on the schedule.
  * Fabian did more work on the IM assembly. It is nearly done and he will start on the RM next week.
 * Type B ongoing issues
  * 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
   * '''Need to be incorporated into the procedure document. Discuss with Takahashi (Mark)'''
   * 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 - expected 6/8.
 * Documents
  * BS Assembly Procedure [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|E1504235 draft]]		   * Mark and Hirata-san worked at Kamioka, with valuable help from Enzo (on loan from Type Bp team).
   * We got all the adapter cables for the BF made (Hirata-san did some work on Monday at Mitaka).
   * We installed the extension for the BF yaw pico on the IM pico adapter cable.
   * We got all the in-vacuum and in-air cabling for the IM OSEMs done.
   * We tried to install the stepper and LVDT adapter cables but realized we didn't have enough information on which wires was which. (We later tracked this info down but did not have time to do anything with it - we would have needed to do the rest of the in-vacuum and in-air cabling and set up the stepper motor and LVDT drivers, so we concentrated on the OSEMs.)
   * We plugged in the IM OSEMs, set gains and offsets, and did a noise test (analysis and klog pending).
   * We mounted the OSEMs on the IRM and routed the cabling neatly.
   * We released the suspension.
   * We adjusted the OSEM mounting plates to center the OSEMs on the flags.
   * We adjusted the OSEMs in/out to midrange.
   * The suspension is now ready for OSEM-OSEM TFs!
