 * Type B Past Week Summary - weeks of 8/22 and 8/29
  * Fabian, Mark, Zhao-kun and Yokogawa-kun did BS installation at Kamioka:
   * Weighed the BF, SF and dummy BS (in mirror box).
   * Moved the geophones onto the optical table, clamped them down and took another time series for analysis.
   * Aligned the IM, installed the extra trim masses, tested the picos and weighed the whole assembly.
   * Placed vacuum flanges and cleaned D-Sub cables ready for routing to the rack.
   * Realigned and immobilized the optical table (which had been bumped).
   * Made safety improvements on the second floor (new safety rail, new arrangement of floor pieces, caution tape around holes)
   * Suspended the dummy BS. Currently however it is not hanging correctly, but is off in the +Y direction by several mm relative to the mirror box.
   * We set up the BS OL, using one of the wheeled chests of drawers as a base and using the OL breadboard from the PR2 assembly frame.
  * Hirata-san made a 3D assembly model for SR2 and added the optical design.
  * Hirata-san worked with Uchiyama-san to solve the 90° rotation problem. It turns out the "box" part with the pistons can be rotated, so we can build the SR2 according to the original design.
  * Hirata-san investigated the puzzle of the BF-IM maraging rods, where the 2D drawings and 3D CAD do not agree. Fortunately the actual parts seem to agree with the 3D CAD.
  * Hirata-san washed 3 OSEMs (last of initial 10 for BS) and parts for two BFs (for Type A). He moved the BF parts into the clean room and will assemble them with ATC staff from next Wednesday 9/7.
 * Type B ongoing issues
  * Longer cables for BF->PI and SF->PI - RECEIVED
 * Longer term to-do list
  * Decide position of BS rack - DONE
  * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - NEARLY DONE.
  * Write more of payload assembly procedure (Fabian) - ONGOING
  * Write more of BS Assembly Procedure [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]], [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|E1504235 draft]] (Mark) - ONGOING
  * Lower breadboard installation to be incorporated into the procedure document.
  * Work on BS simulation (Fabian)
  * Do BS Simulink model (Mark, Kokeyama)
  * Do 2D drawings of SR2 parts (Hirata)
  * Redesign SRx IM wire clamps for larger prisms, remachined RMs
  * Order SRM/PRM parts (Hirata/Shoda)
  * Order SRx fasteners (Hirata)		 === Type B (Mark) ===
==== Past week report ====
 * Mark created screens and a macro.txt file for the SR2 and linked to them from the VIS screen.
 * Enzo and Mark did a new overview screen for the BS.
 * Enzo added DIO cards to the rack and connected them to the coil drivers.
 * Fabian and Kozu-kun finished assembling the IM and tested the picos over their full range.
 * Mark and Hirata-san configured and aligned the assembly frame and optical table and craned in the IM ring.
 * Hirata-san noticed some oxidization on several of the L-brackets that will hold the IM horizontally, and we should get them cleaned or machined, but we can probably continue with hanging the system in the meantime.
Line 34: Line 14:
 
==== Plan for week of 12/25 ====
 * Power outage 12/25.
 * Mark, Enzo, Fabian vacation
 * Shoda-san, Kozu-kun, Hirata-san at Kamioka - Hirata-san from Tue, others TBD.
 * Recover after power outage.
 * Create SR2 real-time model.
 * Install new jack receptacles (in SR3 area, second floor) on load gauge adapter (SR2 area, second floor). (Hirata-san)
 * Weigh IM (per Fabian's note in the paper log).
 * Remove L-brackets from bars on IM ring - send for cleaning/remachining.
 * Setup OL for checking pitch of SR.
 * Wipe/blow dust off SR2 frame.
 * Crane IM into frame.

==== Plan for week of 1/9 ====
 * Mark, Fabian, Enzo, Shoda-san at Kamioka Tue-Fri.
 * Hang SR and RM.

==== Vacation Info ====
 * Mark 12/22-1/3
 * Enzo, 12/21-12/27 (but ''not'' 12/28)
 * Fabian 12/22-1/5
