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.
Line 16: Line 8:
==== 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.
 * Mark and Fabian did a huge cleanup of the SR2 area and prepared a workspace for assembling the IM.
 * Fabian did a stocktake of the screws for the SR.
  * We have all we need for the IM, except one type that can be added after the rest of the IP is assembled.
  * We have most of what we need for the rest of the payload, and Hirata-san has ordered the others.
 * Hirata-san worked on SR procurement:
  * Suspension wire
  * SR additional parts (compensation masses, clamps etc)
  * Regular, SDC and BUMAX screws.
  * Additional machining on the BS sapphire prism jig to allow it to be used on the PR/SR mirror box.
  * LBB blade design.
 * Enzo and Kozu-kun (with help from Fujii-kun) worked on export from SUMCON to Matlab, and on filter design.
Line 25: Line 20:
