ATC staff solved this isue quickly and Hirata-san cleaned the piece. * Some ballast discs for the dummy optic were dirty (seen by visual inspection). Hirata-san cleaned them. * Some arrows were cleaned from the mirrors for the dummy optic. * Hirata-san worked on checking Mirapro's assembly frame design - some minor issues with rail system found. * Hirata-san measured another filter. * Hirata-san washed a large batch of parts. * All parts for gluing of dummy BS are in hand. We arranged with Tatsumi-san to glue magnets at Mitaka on 6/6, glue flags at Kashiwa on 6/8, and inspect bonds and bring dummy BS back to Mitaka 6/13. * Mark worked on solutions to allow a [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/VIS/TypeB/dummyBS|larger mirror on dummy BS]]. After discussions with Simon and Akutsu-san we decided to go with a stainless steel plate solution. The gluing can go ahead and we can attach the plates later. * Mark worked on list of items for purchase in FY2016. * 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]]) |
