| * Type B Past Week Summary * Flags and metal prisms ordered; expected 5/31. * New assembly drawing [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5179| D1605179]] focussing on items not part of main chain (and associated screws): * Crane adapter * Lower breadboard blade module (with cable clamps) * IM-RM safety bar ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5127| D1605127]] from last week now obsolete) * 3D assembly changed to have geophones instead of accelerometers (but SRx will probably be per original design - need to revisit circuit diagram) * Concept for load gauge adapter decided (reuse crane adapter plate and jacks from below PI; add Misumi crossbars, cleanroom-compatible chain hoist) * Concept for second floor of clean booth decided (remove all floor panels; add bridge panels at right angles: [[attachment:BS Cleanbooth.pdf]]) * Modified drawings for main assembly frame and drawings for most small parts (jack adapters etc) received from Mirapro. * Wire sizes decided: 300 µm piano wire and 500 µm tungsten (will revisit this later). * Lots of work on [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4817| E1604817]] (Fabian) and [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]] (Mark) |
=== Type B (Mark) === ==== Past week report ==== At Kamioka (Mark, Fabian, Enzo, Hirata-san): * Hirata-san did an inventory of SR and other parts at Kamioka. * Mark and Enzo finalized the geometry matrices for the IP, entered them in MEDM and updated the safe.snap. * Mark, Enzo and Fabian worked with Izumi-san et al. to align the BS. We got the +Y beam fairly close to aligned (to the second gate valve, near IY). ==== Plan for week of 10/30 ==== Kamioka: Mark and Enzo * Continue alignment of BS. * Realign OL. * Work on servos. Mitaka: Fabian and Hirata-san * SR procurement. * New PI GAS FR design. * BS LBB ballast mass design. * SR cable lamp design. |
