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.
 * 		 * Activity report for weeks of 12/26 and 1/2

  * Hirata-san:
   * Modified parts list and screw list for payload.
   * Sent lists to i-ject and asked for preliminary quotes.
   * Made drawings for some jigs (PR hold-down jig) and some parts for payload (PR/SR wire clamps with disposable jaw pieces - improved version with disposable pieces in both primary and secondary clamps).
   * For Type Bp:
    * Searched for PR gluing jigs.
    * Washed and assembled recoilmass base for mirror hanging jigs, and sent them to Kamioka.
    * Washed additional masses for IM and sent them to Kamioka.
   * For others:
    * Washed IMMT plate and sent them to Kamioka.
  * Fabian
   * Designed a pull down system to fix the PR IM to the EQ stop (similar to the SR one).
   * Worked on design of the SR assembly frame. As hoped, the SR version can be almost identical to the BS version.
   * Worked on design of additional trim mass (≈18 kg) for the BS BF.
   * Checked assembly PR/SR drawings. There were a few corrections/changes.
   * Checked fastener list. There were few corrections/changes.
   * Checked component list for the manufacture order. There were few corrections/changes.
   * Helped in searching for the PR gluing jigs.
  * Mark
   * Started design of SR assembly frame (but then passed it to Fabian).
   * Worked on task lists and schedule.
 * Plan for 1/10-13
  * Mark and Fabian at Kamioka:
   * Finish rebalance of IM
   * Reinstall IRM, adjust OSEMs
   * Replace broken Type 3 cable.
   * Do TFs from IRM OSEMs to IRM and IM OSEMs.
   * Cable up and test BF LVDT and fishing rod (time permitting).
   * Disconnect BF and ship back to Mitaka (time permitting).
  * Hirata-san:
   * More SR procurement.
