| ==== Report for week of 3/26 ==== BFs: * BF No. 1: * Fujii-san finished tuning. Optimal load: 52.15[kg]. Resonance frequency: 0.36[Hz]. Optimal height: 64.7[mm]. * We wired the LVDT, Picomotor and Steppermotor. * We measured the keystone tilt at different points and the diferences are within 0.1[mm] * We added cable clamps to the base. * BF No.7: * Fujii-san replaced the blades corresponding to the BS and for the SR type blades. * The yoke position was corrected. * The fishing rod was assembled. * Compression tuning is ongoing. SFs: * Hirata-san and Tanioka-san set up the frame to check the SFs. * SF (B2-5): * Hirata-san, Fujii-san and Tanioka-san checked the optimal load with and without cap. The optimal load changes about 250[g]. * We measured the keystone tilt at different points, and the diferences are within 0.1[mm] * SF (B2-6): * Hirata-san, Fujii-san and Tanioka-san checked the optimal load with and without cap (On going?). * We measured the keystone tilt at different points, and the diferences are within 0.3[mm] SR3/SRM: * Kozu-kun and Enzo finished the SR3 in-air cabling. * Enzo prepared the SR3 and SRM rack in parallel (On going). BS: * Kozu-kun and Enzo helped Enomoto-san troubleshooting the BS Oplev issue (On going). * SF check (Hirata-san++). * We checked the load capacity with and without the cap. * We checked fit of caps. For the SF No. * Add cable clamps to bases. * Add cable clamps and Cu segments to caps (only if they fit well). * Cable LVDTs and steppers. * We finished the SR3 in-air cabling. ==== Plan for week of 4/2 ==== * Mark at Mitaka Mon, Kamioka from Tue. * Shoda-san at Mitaka * Others at Kamioka * -- * Finish BFs tasks (cabling +calibration) * Finish SFs tasks (cabling +calibration) * Add cable clamps to bases. * Glue SR3 mirror? * Add cable clamps and Cu segments to caps (only if they fit well). * Build 2xIM, 2xIRM ==== Plan for week of 4/9 ==== * Shoda-san at Mitaka * Others at Kamioka * -- * Finish IMs and IRMs * Build 1xRM ==== Plan for week of 4/16 ==== * Start SR3 Hang? |
==== 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. * Eleonora and Izumi-san revisited the BS length to tilt coupling, which had degraded, and got it working again. |
