| ==== Report for week of 2/19 ==== * We did TFs from the IM OSEMs. * We secured the cables inside the BF, added the cap and anchored the cables from below the BF to the cap. * We lifted the BF/... section with the load gauge adapter and measured the weight, which was about as expected. * Based on the measured weight, Fabian prepared an 800 g set of masses for the top of the BF. * We added the AF crossbars and the section of the SS below the SF and craned in the SF. * We installed the SF-BF rod and flying saucer and suspended the BF/... section. With the 800 g placed temporarily on the BF, the SF keystone floated at about mid-range. |
==== Report for week of 7/30 ==== * ==== Plan for week of 8/6 ==== * Mark, Enzo, Hirata-san, Fabian, Kozu-kun, Terrence, Panwei at Kamioka Mon-Fri. * Kozu-kun works at Mozumi Mon, Fri, and Thu afternoon. |
