| ==== 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. * Cable/test/adjust IM OSEMs. * Time permitting, do TFs from IM OSEMs to themselves and to optical sensor. |
==== Report for week of 4/9 ==== * We packed away the SRM SF and BF. * After several failed attempts with one secondary prism, Mark finished the SR3 prism/magnet gluing. * Tanioka-kun built two IRMs (less OSEMs). * Enzo built an RM. * Kozu-kun and Enzo calibrated one set of 6 IM OSEMs for SR3. (6 OSEMs for SRM remain to be done.) * Hirata-san aligned the assembly frame, installed the interface bars and IM ring, and installed the IM. |
