==== Past week report ==== * Mark created screens and a macro.txt file for the SR2 and linked to them from the VIS screen. * Enzo and Mark did a new overview screen for the BS. * Enzo added DIO cards to the rack and connected them to the coil drivers. * Fabian and Kozu-kun finished assembling the IM and tested the picos over their full range. * Mark and Hirata-san configured and aligned the assembly frame and optical table and craned in the IM ring. * Hirata-san noticed some oxidization on several of the L-brackets that will hold the IM horizontally, and we should get them cleaned or machined, but we can probably continue with hanging the system in the meantime. |
==== 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. |

(Hirata-san) * Weigh IM (per Fabian's note in the paper log). * Remove L-brackets from bars on IM ring - send for cleaning/remachining. * Setup OL for checking pitch of SR. * Wipe/blow dust off SR2 frame. * Crane IM into frame. ==== Plan for week of 1/9 ==== * Mark, Fabian, Enzo, Shoda-san at Kamioka Tue-Fri. * Hang SR and RM. |
==== Plan for week of 2/19 ==== * Lift BF/... section and check total mass and balance. * Cable and test BF picos. * Add section of SS up to SF ring. * Bring in SF. * Add Cu segments to SF cap. * Hook BF/... section. * Route cables up to under SF. * Check/adjust total mass of BF/... section. |
