| * 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: [[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]]) |
* Activity report for weeks of 12/26 and 1/2 {{{ Dear Mark, I did for Type-B as below, ・modified parts list and screw list for Payload. ・sent lists to i-ject and asked for quotes. (But we need to send latest list again.) ・made drawings for some jigs and some parts for payload. For PR ・searched glueing jigs. ・washed and assembled recoilmass base for mirror hanging jigs, and sent them to Kamioka. ・washed additional masses for IM and sent them to Kamioka. For others ・washed IMMT plate and send them to Kamioka. Best regards, Hirata }}} {{{ Hello, Succinctly, it is as follows: 1. Mechanical design: a. Pull down system to fix the power recycling IM to the EQ stop. b. EQ stop for the BS recoil mass. 2. Checked assembly PR/SR drawings. There were few corrections/changes. 3. Checked fastener list. There were few corrections/changes. 4. Checked component list for the manufacture order. There were few corrections/changes. 5. I helped in searching for the PR mirror box missing pieces at Mitaka.

Hello,
Succinctly, it is as follows:
1. Mechanical design:
a. Pull down system to fix the power recycling IM to the EQ stop.
b. EQ stop for the BS recoil mass.
2. Checked assembly PR/SR drawings. There were few corrections/changes.
3. Checked fastener list. There were few corrections/changes.
4. Checked component list for the manufacture order. There were few corrections/changes.
5. I helped in searching for the PR mirror box missing pieces at Mitaka.
