* Type B Past Week Summary * Fabian finished dummy BS assembly. * Mark and Tatsumi-san glued magnets into both types of BS optic flags, and discs into BS IM flags. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1815 |klog]] Two optic flags had to be redone because the magnets moved while the glue was drying. Hirata-san helped remove the magnets with acetone in the ultrasonic cleaner. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1818|klog]] * Tatsumi-san, Fabian and Mark took the dummy BS to Kashiwa and glued the flags and prisms. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1821|klog]] We will check status on Mon 6/13. * Hirata-san measured another filter. * Hirata-san washed a batch of parts. * Hirata-san worked on work platforms for the installation. * Hirata-san looked for a crane scale for use at the site. (We decided the 500 kg version of the one used at TAMA.) * Hirata-san worked on making some guide parts for the PI installation (Misumi parts with minor additional machining from ATC). * We finalized a design for simple SS mirror parts for the dummy BS with Akutsu-san. They will be made by ATC. * Mark worked on list of items for purchase in FY2016 and on the schedule. * Fabian did more work on the IM assembly. It is nearly done and he will start on the RM next week. * Type B ongoing issues * Wires * Need to decide RM wire thickness and order. Lead time is a few days from Nilaco. * Can we make SR wire breakers bigger? * Fukushima-san will start on machining test soon (as of 5/27). * Not enough crane height problem (Hirata, Saito) - no action since last week * Ballast masses for payload * Initial batch received - ordered extra smaller ones to allow for adjustments. * Lower breadboard stuff * '''Need to be incorporated into the procedure document. Discuss with Takahashi (Mark)''' * Breadboard springs (in manufacture, expected end of July) * Nail-head parts: quote from Mirapro received, not urgent, will be combined with assembly frame order. * Clean bag - expected 6/8. * Documents * 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]] |
