| * Akutsu-san provided a set of cleanroom gear (shoes only slightly too tight!) for use by Mark this week. And Sakamoto-san sent another set from Kamioka to Kashiwa. * The RM, IM and IRM were weighed, and wrapped/packed for shipment to Kamioka. * Mark made a checklist of all the parts of the BS mirror box and gluing jig, to help with collecting the parts from Kashiwa. * Hirata-san removed the remaining glue from the BS primary and secondary prisms, as well as the prisms removed from the PR hanging test mirror. |
* Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka: * Calculated BS pitch correction ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5630|JGW-T1605630]]) * Hung dummy optic and set pitch. * Prepared RM. * Placed vacuum feedthroughs on assembly frame and cleaned D-Sub cables. * Decided position of BS rack with Miyakawa-san. * Measured maraging rods. * Hirata-san made a 3D assembly model for SR2 and added the optical design. * Hirata-san worked with Uchiyama-san to solve the 90° rotation problem. It turns out the "box" part with the pistons can be rotated, so we can build the SR2 according to the original design. * Hirata-san investigated the puzzle of the BF-IM maraging rods, where the 2D drawings and 3D CAD do not agree. Fortunately the actual parts seem to agree with the 3D CAD. * Hirata-san washed 3 OSEMs (last of initial 10 for BS) and parts for two BFs (for Type A). He moved the BF parts into the clean room and will assemble them with ATC staff from next Wednesday 9/7. |

| * OSEMs * Akutsu-san is working to get wide-mouth OSEMs ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1853|2 assembled]]; another few were assembled and a batch of 7 were washed. * Mark worked on the schedule, making the next few weeks more realistic and incorporating the new plan for the SR RMs (the test will be used for SR2 but two more will be made from scratch next financial year). * Longer cables for BF->PI and SF->PI. * Connectors RECEIVED, cables being made. * SR machining test NEARLY DONE. The part looks good and will be used but the ones for SR3 and SRM will be made from scratch. * Lower breadboard stuff * Installation to be incorporated into the procedure document. Mark/Takahashi to discuss. * Breadboard springs - 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 * Weigh IM/RM/IRM (Fabian, Hirata) - DONE but anomalies found. * Pack/ship IM/RM/IRM to Kamioka (Hirata/Fabian) - from 8/1. * Analyze geophone data (Fabian/Shoda) - data taken by Shoda-san; Fabian to find calibration factors. * Remove glue from dummy BS face (Fabian) - MOSTLY DONE. * Reglue flags and prisms (Tatsumi, Fabian) - from Friday 8/5. * 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) |
