 * Type B Past Week Summary
  * 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]])		 === Type B (Mark) ===
==== Past week report ====
At Kamioka (Mark, Ohishi-san, Fabian, Enzo, Hirata-san, Yoshioka-kun, Kozu-kun):
 * We solved the problem with the OSEMs: cables had been plugged into the LED current monitor outputs, not the PD outputs.
 * We solved a problem with the real-time model freezing which turned out to be the IO chassis having lost power.
 * We took some mass off the IM to allow for the weight of the cables, and readjusted it in pitch and roll.
 * We aligned the IM

==== Plan for week of 8/28 ====
Kamioka: Mark (except Tue), Ohishi-san, Fabian (except Tue), Enzo (except Tue), Hirata-san, Yoshioka-kun (Fri), Kozu-kun (Thu, Fri).
 * Fix/adjust IRM OSEMs.
 * Add BF cap; cable and test BF-1 and BF-2 picos.
 * Lift and weigh BF/IRM/IM/RM/BS; adjust ballast mass.
 * Crane in SF.
 * Suspend BF/IRM/IM/RM/BS.

==== Plan for week of 9/4 ====
 * Install SF cap; route cables.
 * Lift and weigh SF/BF/IRM/IM/RM/BS.
 * Adjust SF ballast.

==== Vacation Info ====
Mark: TBD Mid-Oct
