| * Type B Past Week Summary * Mark and Fabian worked at Kamioka: * All the parts for the security structure were located. The clamp pieces for the IM are being taken back to Mitaka to have extra screw holes added. * The BS/PR2/SR2 area was cleaned and tidied to allow floor removal and assembly frame construction. * 21 "Type 1" cables (PI-Flange, Signal) and 15 "Type 5" cables (OSEM) were tested. They all passed. Sufficient tested "Type 2" cables (PI-Flange, Motor) were located in the PR3 area. * Hirata-san worked on the Inventor assembly, adding views (originally defined by Mark) of the different phases of construction. * Hirata-san shipped 7 SFs and some parts to Kamioka. * Hirata-san made assembly drawings of the damper rings and cable clamps for SR. * Hirata-san liaised with Mirapro about the frame assembly. * Type B ongoing issues * Wires * Need to decide RM wire thickness and order BS and RM wires. Lead time is a few days from Nilaco. * OSEMs * Akutsu-san is working to get wide-mouth OSEMs * Longer cables for BF->PI and SF->PI. * Takahashi-san has ordered extra connectors (due any day) and will get a company to make the cables. * Feedthrough Adapters * Need large quantity of male and female D-Sub 9, IDC ribbon connectors - Takahashi-san is getting a quote. * Can we make SR wire breakers bigger? * Fukushima-san will start on machining test soon (as of 5/27). * Installation stuff * Crane scale - RECEIVED * Ballast masses for payload * Initial batch received - ordered extra smaller ones to allow for adjustments. * 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: quote from Mirapro received, not urgent, will be combined with assembly frame order. * 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]] |
* Hirata-san: * Updated the 3D assembly model for BS (among other issues, it turned out that parts were not correctly mated near where the suspension sits on the hydraulic jacks in the tank). * Liaised with IJECT. * Made an inventory for Type B (BS and SR). * Packed and shipped second winch to Kamioka. * Packed some jigs for adjusting BF blades. * Attended NINS information security seminar. * Attended the public hearing for the Opt-IR Research Division Chief Election. * Mark, Fabian, Enzo * Cabled IM picos and used IM yaw pico for adjusting RM. (Later, a wire broke at the connector, disabling the IM yaw, but we were able to continue by manually rotting the pic.) * Helped Takahashi-san in adjusting BF. * Initial round of adjustment made transverse perfect but overshot in longitudinal and made vertical unstable. * Second round of adjustment made vertical stable but left longitudinal offset. * Concluded that we can probably manage without bringing the BF back to Mitaka, but it will take some careful surveying of the existing offset and several more days of adjustment. |
