Line 5: Line 5:
 * Hirata-san produced a near-final Inventor assembly of the BS on the assembly frame, for use in writing the assembly procedure.
  * Includes assembly frame modifications suggested by Mirapro, including feet, wheels, lifting eyes, thicker crossbars under BF, IM etc.
  * Includes final rail system except for interface plate to mirror box.
  * Includes full PI with ballast masses.
  * Includes cable clamps.
  * Includes correct versions of BF and SF.
  * Includes new BF pushrod parts to work around different placement of blade screws in new version of BF.
  * Includes cleanbag support bars.
  * Includes key parts of mirror box (enough to check for interference) - needs more work.
  * Does not include various invisible duplicate assemblies that had been present due to cut and paste.
  * After a few more improvements, the new assembly will be sent back to Mirapro.
 * Got status from Miyakawa-san on electronics - there should be enough of the boxes AEL is supplying.
 * Cleanbag design was finalized; Aso-san is ordering: [[attachment:160419-ﾁｬﾝﾊﾞｰｶﾊﾞｰⅡ型.pdf]]
 * Quote for flags and prisms was received, but expensive - may drop rigid flag design.
 * The mirror box will require only very minor modifications for flags and prisms - Tatsumi-san will arrange immediately.
 * Fabian worked on understanding Sekiguchi-san's control design to help decide optimum wire thickness.
 * Mark worked on install procedure and schedule.
 * Takahashi-san enquired with NIKHEF about oscillator cards for LVDT chassis - lead time would be 3-4 months.
 * 		=== Type B (Mark) ===
==== Past week report ====

 * 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.

==== Vacation Info ====
 * Mark 12/22-1/3
 * Enzo TBD, probably 12/22-1/3
 * Fabian 12/22-1/5
 * Hirata-san 12/21-22 (conference)
