Type B Past Week Summary
- Mark
  - Updated the BS circuit diagram D1503600:
    - Added information on the binary IO.
    - Renamed channels to conform to Okutomi-kun's new scheme.
    - Made the ADC/DAC channel assignment consistent and more logical.
    - Updated the stepper motor sections with info about the new driver chassis.
  - Worked on schedule.
  - Updated the installation procedure with lessons learned from the last few weeks.
  - Downloaded Hirata-san's Inventor model of the BS in the tank and starting thinking about installation of the suspension and lower bread board.
  - Mark and Hirata-san worked on collecting parts and tools that will be needed for cabling of the BS next week. (11 special-purpose cables need to be made for the picos/steppers/OSEMs/LVDT on the RM/IRM/IM/BF and, time permitting, 2 more for the SF.)
- Hirata-san
  - Updated the BS 3D Assembly with the new rods and receptacles.
  - Made 2D drawings of SR2 and SR3 (ongoing).
  - Made SRM 3D assembly (ongoing)
  - Asked for and got quotes for hexagon cable clamps. Takahashi-san ordered the PEEK components. Next week Hirata-san will look for parts that should already be at Kamioka.
  - Washed screws for hexagon cable clamps and shim rings for Fabian.

 Line 6:
-  * 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]])
