| * Hirata-san: * Updated the 3D assembly model for BS (among other issues, it turned out that parts were not correctly mated near where the suspension sits on the hydraulic jacks in the tank). * Liaised with IJECT. * Made an inventory for Type B (BS and SR). * Packed and shipped second winch to Kamioka. * Packed some jigs for adjusting BF blades. * Attended NINS information security seminar. * Attended the public hearing for the Opt-IR Research Division Chief Election. * Mark and Fabian at Kamioka (plus Enzo for 2 days): * Finished rebalance of IM * Reinstalled IRM, adjusted OSEMs * Replaced broken Type 3 cable on IM-H1 OSEM. * Fixed issues with k1visbs real-time model. * Started TFs from IRM OSEMs to IRM and IM OSEMs. * Mark, Fabian and Enzo * |
=== Type B (Mark) === ==== Past week report ==== At Kamioka (Mark, Enzo, Hirata-san, Yoshioka-kun): * We lubricated the stuck screw at the top of the security structure with stuck and were able to remove it. * Enzo disconnected and removed or coiled many in-vac cables at the PI level to free it. * We craned the PI. There was a minor safety incident - see below. * Hirata-san set up the filter service area, and we moved in a BF intended for one of the SRs (BF#3). * Fabian and Hirata-san worked out a method for characterizing a single spring, and Fabian finished characterizing the first one. * We did a big tidy-up and clean-up of the area, especially the corner where we intended to do the gluing. * We set up the BS gluing jigs and applied the glue. We will check the results on Monday. ==== Plan for week of 7/24 ==== Full team at Kamioka from Mon-Fri, except Hirata-san (Tue-Fri) and Enzo (vacation). * Check results of gluing. * Finish disassembly. * Finish BF rebuild. * Remove LBB rings. * Recheck alignment of assembly frame and centering of optical table. * Install IM, suspend BS and RM. ==== Plan for week of 7/31 ==== Full team at Kamioka from Mon-Fri, except Fabian (Mon-Thu) and Enzo (vacation). * Weigh/trim BS/RM/IM. * Bring in rebuilt BF.
