| * 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]]) |
=== Type B (Mark) === ==== Past week report ==== At Kamioka (Mark, Fabian, Hirata-san, Yoshioka-kun): * We reconfigured the top of the assembly frame. * We cleaned the assembly frame, blowing dust out of the grooves and wiping all surfaces. * We recentered the optic table in the bottom of the frame and adjusted the frame until the top was centered over the optic table. We also recentered the trolleys. * We re-installed, centered and leveled the IM. * We solved two issues with the new wire clamps: * Some holes were not properly threaded - Hirata-san retapped them. * Some locating pins were loose - we glued them. * We mounted the BS mirror box on the trolley and brought it under the IM. * We installed the winch system and the 300 µm wires for the BS. * We set up the optical lever. * Hirata-san finished the new BF.

Past week report
At Kamioka (Mark, Fabian, Hirata-san, Yoshioka-kun):
- We reconfigured the top of the assembly frame.

- We recentered the optic table in the bottom of the frame and adjusted the frame until the top was centered over the optic table. We also recentered the trolleys.
- We re-installed, centered and leveled the IM.
- We solved two issues with the new wire clamps:
- Some holes were not properly threaded - Hirata-san retapped them.
- Some locating pins were loose - we glued them.
- We mounted the BS mirror box on the trolley and brought it under the IM.
- We installed the winch system and the 300 µm wires for the BS.
