| * BF No. 1: * Fujii-san finished tuning. Optimal load: 52.15[kg]. Resonance frequency: 0.37[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: * Tanioka-san and Fujii-san replaced the blades corresponding to the BS 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]. The cap didn't came out smoothly. * We measured the keystone tilt at different points, and the diferences are within 0.1[mm] (65.5, 65.5, 65.5, 65.4) * 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] (63.7, 63.5,63.8, 63.8) SR2/SR3/SRM: * Kozu-kun and Enzo finished the SR3 in-air cabling. * Enzo prepared the SR3 and SRM rack in parallel (On going). * We got new power supply for the SR2 Rack. Before, the power was coming from the BS rack. BS: * Kozu-kun and Enzo helped Enomoto-san troubleshooting the BS Oplev issue (On going). Shipping: * We received the LBB parts for SR2. * We received the Payload parts (IM and IRM) this morning. ==== Plan for week of 4/2 ==== * Mark at Mitaka Mon, Kamioka from Tue. * Shoda-san at Mitaka * Others at Kamioka |
==== Plan for week of 6/18 ==== * Mark Enzo, Hirata-san, Kozu-kun, Terrence at Kamioka Mon-Fri. |
