 * Type B Past Week Summary
  * Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka:
   * Calculated BS pitch correction ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5630|JGW-T1605630]])
   * Hung dummy optic and set pitch.
   * Prepared RM for hanging (adding OSEMs etc). One OSEM (#24) had wobbly leads and was brought back to Mitaka for rework.
   * Placed vacuum feedthroughs on assembly frame and cleaned initial batch (4) of D-Sub cables.
   * Decided position of BS rack with Miyakawa-san.
   * Measured various maraging rods and the rod holders on the SF.
   * Placed safety rails, rearranged floor panels, cleaned new floor panels, and otherwise improved safety.
  * Hirata-san:
   * Made new 3D models of the maraging rods for PRx and SRx
   * Made new collet design for PRx and SRx (3D and 2D).
   * Made new IM flag design for PRx and SRx (3D and 2D).
   * Washed lots of Type A BF parts and OSEM parts.
   * Cleaned the BS BF-IM maraging rod and organized the rest of the stock of rods.
   * Measured some BF part dimensions.
   * Pre-assembled parts for BFs.
 * Type B ongoing issues
 * Longer term to-do list
  * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - NEARLY DONE.
   * Part "disk security" top has to be modified - screw positions do not match.
  * 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)

==== Past week report ====
Line 36: Line 8:
   * Mark worked on SR2 planning.
 * Mark thought through what would be required to swap an optic (e.g., SRM) in situ (JGW-T1707436).
 * Hirata-san tried removing disks from IM flags (so we could reuse them in flag bases and make a complete set for SR2) but only got 1 of 4 out.
 * Hirata-san ordered more disks for IM flags.
 * Hirata-san asked for quotes on SF LBB blades.
 * Hirata-san got a reduced quote for the LBB damper rings.
 * Hirata-san received and cleaned suspension wires for the SR.
 * Fabian worked on the SR mass budget.
 * Fabian worked out the COM of the SR2 optic, and Mark used it to derive the proper prism positions.
 * Enzo and Kozu-kun worked on control filter design and installation.

==== Plan for week of 11/27 ====
 * Fabian at commissioning workshop
 * Hirata-san at Kamioka Tue-Fri to work with Mirapro on SRM LBB installation.
 * All others (Mark, Enzo, Shoda-san, Kozu-kun) at Kamioka to start SR2 assembly.
  * Mark from Mon lunchtime.
  * Kozu-kun from Mon lunchtime through Wed.
  * Mirror gluing.
  * SR2 rack setup.

==== Plan for week of 12/4 ====
 * All at Kamioka
  * IM assembly and pico test.
  * Assembly frame alignment and optical table centering.
  * OL setup.
