| * Type B Past Week Summary * Mark and Hirata-san at Mitaka * Gathered parts for cable making. * Mark and Hirata-san at Kamioka: * Replaced the floor panels that had been taken from the PR2 area (filling in the hole in the floor) and found/installed two new panels to act as bridges near the BS assembly frame. * Installed two more LPCDs and the stepper motor driver in the PR2 rack. * Ran cables from the rack to the second and third sat amps (for the IRM OSEMs). * Added a second DIO card in the rack and connected it to the BIO inputs and outputs of the new LPCDs. * Started making extension cables for RM-H2 and -H3 OSEMs but gave up due to complicated grounding arrangement. * Washed four 40-cm D-Sub-9 ribbon cables to use as temporary extensions (maybe also for H1/H4). * Added extension to the IM pico cable for the BF yaw pico. * Made LVDT adapter cable. * Mark worked on schedule. |
=== 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.
