  * Fabian did inventory of parts/fasteners for dummy BS, RM, IM and IRM - almost all at Mitaka. A handful (picos, pico drivers) will be brought back from Kamioka.
  * Fabian continued work on Mathematica and Matlab models of the BS and control system. He now gets much better agreement after correcting discrepancies between the parameter sets.
  * Hirata-san worked on organizing:
   * Checking Mirapro assembly frame drawings
   * Ordering missing screws and small items (screws for dummy mass, fine pitch M8 for RM)
   * Work platforms and clean booth second floor arrangement.
   * Load gauge adapter and associated parts
   * Possible fall-back plans for the rods connecting the security structure to the PI.
   * Design for additional trim masses (existing design had no provision for adding/removing).
  * Fabian prepared a work space in the ATC cleanroom and moved in nearly all the parts for the dummy BS, RM, IM and IRM.
  * Fabian finally got perfect agreement between the Mathematica and Matlab models of the BS. (The wire thicknesses had in µm instead of mm, leading to some modes off by 1E3.)
  * Hirata-san remeasured the BF for the BS. He noted that the cap went on and came off easily (unlike some other filters).
  * Hirata-san worked on final details of the Mirapro order for the assembly frame.
  * Hirata-san and Takahashi-san washed a large batch of parts.
  * Tatsumi-san will glue flags, sapphire primary prisms and metal secondary prisms to the dummy BS some time in the week of 6/8. Fabian and possibly Mark and/or Hirata-san will travel to KEK to help and observe.
  * 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]])
