 * 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 ====
At Kamioka (Mark, Ohishi-san, Enzo, Yoshioka-kun, Kozu-kun):
 * We finished installing the RM OSEMs and installed the new Type5-2.2 and 5-2.4 OSEM cables.
 * We hung the RM and set its pitch.
 * We doubled-checked the BS and RM pitch, tightened the clamps and removed the winch system.
 * We installed the bottom section of the security structure to protect the RM/BS.
 * We lifted the IM/RM/BS section and weighed it. It was about 1.25 kg too heavy for the new BF, so we improvised a lighter set of ballast masses.
 * We installed the section of the security structure up to the BF ring, and the BF crossbars and jacks of the assembly frame.
 * We brought in the new BF.
 * We installed the BF-IRM rods and IRM top plate.
 * We reinstalled the IM flags and other items that had been taken off to use the winch system.
 * We hooked the BF-IM rod (with hex cable clamp). (We did not unlock the BF keystone.)
 * We cabled and tested the IM-PIT, IM-ROL and IM-YAW picos and the BF FR stepper (but not, yet, the BF LVDT).

 * Remove LBB blade units from PI, then remove blades and send for remachining.
 * Remove LBB rings from chamber and send for recleaning.
 * Unlock BF, adjust ballast masses on IM/RM/BS to correct pitch/roll/vertical.
 * Test, calibrate BF LVDT.
