| * Type B Past Week Summary * Fabian took photos of the cleanroom in the ATC to help decide whether it is a good place to assemble PIs for Type A/B. * Hirata-san ordered and received wire for the BS and RM (will be cleaned 7/19). * Hirata-san received remachined locking parts for the IM (will be cleaned 7/19). * Hirata-san ordered additional Misumi parts to be used with the IM locking parts. * Fabian and Hirata-san weighed the masses that they've been constructing in the cleanroom and found a 600 g discrepancy from the Inventor (too light) for the IM. * Hirata-san ordered a medium-capacity scale to weigh the masses of the individual parts more precisely. * Hirose-san and his team successfully removed the misglued prisms from the dummy BS. * Fabian travelled to Kashiwa and removed most of the glue from the face of the dummy BS (where the flags had been). There is still some adhesive remaining on both the face and barrel, which will require more work and a second trip. * Shoda-san took a suitable segment of geophone noise data for analysis. Fabian will track down the calibration factors. * Type B ongoing issues * OSEMs * Akutsu-san is working to get wide-mouth OSEMs * 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) * Nail-head parts - RECEIVED. * 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 * Apply grease to jacks for assembly frame (Takahashi) * Finish assembly of BS IM, RM and IRM (Fabian). * Weigh IM/RM/IRM (Fabian, Hirata) * Pack/ship IM/RM/IRM to Kamioka (Hirata/Fabian). * Analyze geophone data (Mark, Shoda) * Remove glue from dummy BS face (Fabian) * Remove prism from dummy BS (Hirose, Fabian?) * Reglue flags and prisms (Tatsumi, Fabian) * Buy wire for BS and RM (Hirata) * Clean wire for BS and RM (Hirata) * 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) * Apply vacuum grease to jacks for BS assembly frame (Takahashi) * 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) |
