| * Fabian prepared a work space in the ATC cleanroom and moved in nearly all the parts for the dummy BS, RM, IM and IRM. * Fabian finally got perfect agreement between the Mathematica and Matlab models of the BS. (The wire thicknesses had in µm instead of mm, leading to some modes off by 1E3.) * Hirata-san remeasured the BF for the BS. He noted that the cap went on and came off easily (unlike some other filters). * Hirata-san worked on final details of the Mirapro order for the assembly frame. * Hirata-san and Takahashi-san washed a large batch of parts. * Tatsumi-san will glue flags, sapphire primary prisms and metal secondary prisms to the dummy BS some time in the week of 6/8. Fabian and possibly Mark and/or Hirata-san will travel to KEK to help and observe. * Mark worked more on [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235|E1504235 BS Assembly Procedure]] ([[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|Draft on OneDrive]]) |
* 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.
