| * Type B Past Week Summary * Mark and Fabian went to Kashiwa to clean up glue residue on the dummy BS and do a fit/function test of Tatsumi-san's modified tooling. * Most of the remaining glue came off with soaking in acetone, but there is still some in the machining grooves in the Al surface. Probably more work is required. * A set of cleanroom shoes borrowed from the ATC disintegrated when worn (the plastic had perished from age), which put small pieces of foam all over the floor in Hirose-san's cleanroom and required a lot of clean-up with a sticky roller! Cleanroom suits and shoes for use by Type B team at Mitaka/Kashiwa have been ordered, but will take another week to arrive. * The flag holding parts are now much easier to place and remove, much reducing the risk of breaking flags after gluing. * The sapphire and metal prisms from both the first BS gluing and the PR3 hanging test mirror were brought back to Mitaka for ultrasonic cleaning to remove glue, so they can be reused. * Hirata-san found the SR versions of the screws for immobilizing the IM and IRM. These fit much better than the BS ones (despite being the same design) and will be used for the BS. * Type B ongoing issues * OSEMs * Akutsu-san is working to get wide-mouth OSEMs ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1853|2 assembled]]; first 4 expected to be assembled and washed by 8/8) * Longer cables for BF->PI and SF->PI. * Connectors RECEIVED, cables being made. * SR machining test ongoing. * Lower breadboard stuff * Installation to be incorporated into the procedure document. Mark/Takahashi to discuss. * Breadboard springs (in manufacture, expected end of July) * 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]] * To-do list during Mark's vacation * Weigh IM/RM/IRM (Fabian, Hirata) - DONE but anomalies found. * Pack/ship IM/RM/IRM to Kamioka (Hirata/Fabian). * Analyze geophone data (Fabian/Shoda) - data taken by Shoda-san; Fabian to find calibration factors. * Remove glue from dummy BS face (Fabian) - partly done. * Reglue flags and prisms (Tatsumi, Fabian) * Clean wire for BS and RM (Hirata) - DONE * Get new winch parts for new wire diameters - design received from Ikenoue-san * Do fit/function test of winches (Fabian/Hirata) * Ship winches to Kamioka (Hirata/Fabian) * Work on BS simulation (Fabian) * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - ONGOING. * Write more of payload assembly procedure (Fabian) * Write more of main assembly procedure (Mark) * Longer term to-do list * 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) * Check SR RM machining test progress (Hirata) |
