 * Type B Past Week Summary
  * Flags and metal prisms ordered; expected 5/31.
  * New assembly drawing [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5179| D1605179]] focussing on items not part of main chain (and associated screws):
   * Crane adapter
   * Lower breadboard blade module (with cable clamps)
   * IM-RM safety bar ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5127| D1605127]] from last week now obsolete)
  * 3D assembly changed to have geophones instead of accelerometers (but SRx will probably be per original design - need to revisit circuit diagram)
  * Concept for load gauge adapter decided (reuse crane adapter plate and jacks from below PI; add Misumi crossbars, cleanroom-compatible chain hoist: [[attachment: Crane Frame.pdf]])
  * Concept for second floor of clean booth decided (remove all floor panels; add bridge panels at right angles: [[attachment:BS Cleanbooth.pdf]])
  * Modified drawings for main assembly frame and drawings for most small parts (jack adapters etc) received from Mirapro.
  * Wire sizes decided: 300 µm piano wire and 500 µm tungsten (will revisit this later).
  * Lots of work on [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4817| E1604817]] (Fabian; [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!191&authkey=!AMe0pdcd9GDm1H0&ithint=folder%2cwebloc|Draft on OneDrive]]) and [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]] (Mark; [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder%2cwebloc|Draft on OneDrive]])		 === Type B (Mark) ===
==== Past week report ====

 * We brought the SR2 optic into the tunnel and moved it into the good mirror box. The spare mirror was moved into the not-so-good mirror box.
 * Enzo assembled the SR2 rack and laid all the long cables from the rack into the cleanbooth. (Hayakawa-san can now proceed with the rebuilding of the changing cleanbooth.)
 * Mark and Shoda-san took data for calibrating and diagonalizing the OL. (Due to the odd angle of the first steering mirror, the beam pattern is rotated by 62° at the QPD.)
 * Enzo found nearly all in-vacuum cables.
 * Enzo and Shoda-san got several more loops closed on the BS.
 * Mark found three geophone pods and two feedthrough adapters for SR2 (now have 3 FAs but need 4).
 * Mark took out S-numbers for anonymous boxes in the SR2 and put yellow stickers supplied by Tomura-san on them.
 * Hirata-san worked on SR procurement.
 * Hirata-san worked with Mirapro to get the SRM LBB installed in the tank.
 
==== Plan for week of 12/4 ====
 * Mark at Kamioka.
 * Fabian at f2f satellite meeting Mon, then Kamioka.
 * Enzo at f2f then Mitaka.
 * Hirata-san at Kamioka Mon-Thu, Mitaka Fri.
 * Kozu-kun Thu only.
 * Mirror gluing.
 * IM assembly and pico test.

==== Plan for week of 12/11
 * Mark, Fabian, Enzo, Hirata-san, Shoda-san at Kamioka.
 * Kozu-kun Mon-Thu only.
 * Assembly frame alignment and optical table centering.
