==== 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 (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4073|4073]]). * 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). ==== Plan for week of 2/5 ==== * Enzo on vacation; all others at Kamioka. * - * Make in-air pico adapter cables. * Calibrate LVDT. * Test IM picos and BF yaw pico. * Test FR. * Install ballast mass in BF. * Build IRM around IM. |
==== Report for week of 3/19 ==== * Fujii-kun successfully assembled and tested a geophone pod (klogs 4492, 4508). * Hirata-san set up the dummy BS to soak off the sapphire prisms. (In process) * Shoda-san, Hirata-san and Enzo finished the assembly of 12 OSEMs. We still need to measure the maximum output (In process) * We will send the OSEMs to Kamioka today. |
