| * 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: [[attachment: Crane Frame.pdf]]) * 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; [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!191&authkey=!AMe0pdcd9GDm1H0&ithint=folder%2cwebloc|Draft on OneDrive]]) and [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]] (Mark; [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder%2cwebloc|Draft on OneDrive]]) |
* Mark and Hirata-san worked at Kamioka, with valuable help from Enzo (on loan from Type Bp team). * We got all the adapter cables for the BF made (Hirata-san did some work on Monday at Mitaka). * We installed the extension for the BF yaw pico on the IM pico adapter cable. * We got all the in-vacuum and in-air cabling for the IM OSEMs done. * We tried to install the stepper and LVDT adapter cables but realized we didn't have enough information on which wires was which. (We later tracked this info down but did not have time to do anything with it - we would have needed to do the rest of the in-vacuum and in-air cabling and set up the stepper motor and LVDT drivers, so we concentrated on the OSEMs.) * We plugged in the IM OSEMs, set gains and offsets, and did a noise test (analysis and klog pending). * We mounted the OSEMs on the IRM and routed the cabling neatly. * We released the suspension. * We adjusted the OSEM mounting plates to center the OSEMs on the flags. * We adjusted the OSEMs in/out to midrange. * The suspension is now ready for OSEM-OSEM TFs! |
