| * Type B Past Week Summary * There were multiple issues with the dummy BS flag/prism gluing [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1830 |klog]]. The sapphire prisms will need to be removed and reapplied. Hirose-san is going to organize this. He wants to try the cup that had been made for the PR2 on the actual PR2 and then see if a new cup is needed for the BS (considering the different radius). * Hirata-san added the optical layout information to the BS Inventor assembly. He requested tank information from Mirapro so he can continue to do SR2/3/M. * Fabian finished the IM assembly and started on the IRM and RM. Some of the IRM panels had been improperly wrapped and really should be re-cleaned. The MPC (multi-purpose cube) on the RM will need some rework. * Mark scheduled a review for Thursday 6/16. * 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 * 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). * Not enough crane height problem (Hirata, Saito) - no action since last week * Installation stuff * Crane scale - quote received * Work platforms - 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. Mark/Takahashi to discuss. * Breadboard springs (in manufacture, expected end of July) * Nail-head parts: quote from Mirapro received, not urgent, will be combined with assembly frame order. * Clean bag - RECEIVED. * Documents * BS Assembly Procedure [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]], [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|E1504235 draft]] |
