| ==== Report for week of 1/29 ==== * We moved the top filter intended for SR2 (#1) into the SR3 cleanbooth. * Unfortunately we noticed one of the blades had many small X-shaped stress fractures on the top surface (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4058|4058]]). * We moved the top filter entered for SR3 (#3) into the SRM cleanbooth and inspected the blades. Two had one smallish stress fracture each and one had a huge fracture and looks close to failing (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4061|4061]]). * We referred the BS OL. * We removed the BS tank lid and inspected the BS top filter blades. They seemed fine. * Hirata-san received and washed some ferromagnetic disks for IM flags and other small parts. * Hirata-san moved the BF with the tilted keystone (#1) out of the cleanbooth in preparation for rebuilding. * Hirata-san placed the second order for payload parts, and an order for remachining of nuts for cable clamps on rods. * Fabian measured the gain of the ADC system (homework from the Commissioning Workshop). |
==== Report for week of 4/9 ==== * Mark glued prisms and magnet/standoff assemblies on the SR3. The SR3 needed to be raised in the box by 0.7 mm to make the prisms go on at the right height, which was done using M4 washers under the PEEK feet. * Mark glued ferromagnetic disks on the last 5 IM flags. This completes 2 sets, for SR3 and SRM. * Mark configured two pico motor drivers ordered by Takahashi-san as SR3-IM and SRM-BF. * Enzo and Kozu-kun finished preparing and calibrating the SF and BF for SR3 and almost entirely finished with those for SRM. * Hirata-san worked on building two IMs for SR3 and SRM. The SR3 one just needs to have flags attached and to be weighed; the SRM needs another few hours work. * Shoda-san worked on the design of the metal SRM, on the LBB ballast mass, and on the plans for testing the BS in bKAGRA Phase 1. |
