* Type B Past Week Summary * 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]]) |
