* 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. * 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-チャンバーカバー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 ==== At Kamioka (Mark, Enzo, Hirata-san, Yoshioka-kun): * We lubricated the stuck screw at the top of the security structure with stuck and were able to remove it. * Enzo disconnected and removed or coiled many in-vac cables at the PI level to free it. * We craned the PI. There was a minor safety incident - see below. * Hirata-san set up the filter service area, and we moved in a BF intended for one of the SRs (BF#3). * Fabian and Hirata-san worked out a method for characterizing a single spring, and Fabian finished characterizing the first one. * We did a big tidy-up and clean-up of the area, especially the corner where we intended to do the gluing. * We set up the BS gluing jigs and applied the glue. We will check the results on Monday. ==== Plan for week of 7/24 ==== Full team at Kamioka from Mon-Fri, except Hirata-san (Tue-Fri) and Enzo (vacation). * Check results of gluing. * Finish BF rebuild. * Recheck alignment of assembly frame and centering of optical table. * Install IM, suspend BS and RM. ==== Plan for week of 7/31 ==== Full team at Kamioka from Mon-Fri, except Fabian (Mon-Thu) and Enzo (vacation). * Weigh/trim BS/RM/IM. * Bring in rebuilt BF. Vacation Info: Hirata-san: Thu 7/20 through Mon 7/24 Enzo: Sat 7/22 through Sun 8/6 Fabian: Fri 8/4 through Mon 8/21 Mark: TBD Mid-Oct |
