| * 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]] |
* Mark * Updated the BS circuit diagram [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=3600|D1503600]]: * Added information on the binary IO. * Renamed channels to conform to Okutomi-kun's new scheme. * Made the ADC/DAC channel assignment consistent and more logical. * Updated the stepper motor sections with info about the new driver chassis. * Worked on schedule. * Updated the installation procedure with lessons learned from the last few weeks. * Downloaded Hirata-san's Inventor model of the BS in the tank and starting thinking about installation of the suspension and lower bread board. * Mark and Hirata-san worked on collecting parts and tools that will be needed for cabling of the BS next week. (11 special-purpose cables need to be made for the picos/steppers/OSEMs/LVDT on the RM/IRM/IM/BF and, time permitting, 2 more for the SF.) * Hirata-san * Updated the BS 3D Assembly with the new rods and receptacles. * Made 2D drawings of SR2 and SR3 (ongoing). * Made SRM 3D assembly (ongoing) * Asked for and got quotes for hexagon cable clamps. Takahashi-san ordered the PEEK components. Next week Hirata-san will look for parts that should already be at Kamioka. * Washed screws for hexagon cable clamps and shim rings for Fabian. |
