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]]) |

- Type B Past Week Summary
- Akutsu-san provided a set of cleanroom gear (shoes only slightly too tight!) for use by Mark this week. And Sakamoto-san sent another set from Kamioka to Kashiwa.
- The RM, IM and IRM were weighed, and wrapped/packed for shipment to Kamioka.
- Mark made a checklist of all the parts of the BS mirror box and gluing jig, to help with collecting the parts from Kashiwa.
- Hirata-san removed the remaining glue from the BS primary and secondary prisms, as well as the prisms removed from the PR hanging test mirror.
- Type B ongoing issues
- OSEMs
Akutsu-san is working to get wide-mouth OSEMs (2 assembled; another few were assembled and a batch of 7 were washed.
- Mark worked on the schedule, making the next few weeks more realistic and incorporating the new plan for the SR RMs (the test will be used for SR2 but two more will be made from scratch next financial year).
Longer cables for BF->PI and SF->PI.
- Connectors RECEIVED, cables being made.
- SR machining test NEARLY DONE. The part looks good and will be used but the ones for SR3 and SRM will be made from scratch.
- Lower breadboard stuff
- Installation to be incorporated into the procedure document. Mark/Takahashi to discuss.
- Breadboard springs - RECEIVED.
- Documents
