| ==== Report for week of 3/26 ==== BFs: * 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 differences 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 come out smoothly. * We measured the keystone tilt at different points, and the differences 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 differences are within 0.3[mm] (63.7, 63.5,63.8, 63.8) SR3/SRM: * Kozu-kun and Enzo finished the SR3 in-air cabling. * Enzo prepared the SR3 and SRM rack in parallel (On going). SR2: * Hirata-san tested the safety bars in the SR2 area. * 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 * -- * Finish BFs tasks (cabling +calibration) * Finish SFs tasks (cabling +calibration) * Add cable clamps to bases. * Add cable clamps and Cu segments to caps (only if they fit well). * Build 2xIM, 2xIRM * Glue SR3 mirror? ==== Plan for week of 4/9 ==== * Shoda-san at Mitaka * Fujii-san at Mitaka * Tanioka-san at Mitaka? * Others at Kamioka * -- * Finish IMs and IRMs * Build 1xRM * Glue SR3 mirror? ==== Plan for week of 4/16 ==== * Shoda-san at Mitaka * Fujii-san at Mitaka * Tanioka-san at Mitaka? * Others at Kamioka * -- * Start SR3 Hang? ==== Plan for week of 4/23 ==== * Shoda-san at Mitaka * Fujii-san at Mitaka? * Tanioka-san at Mitaka? * Others at Kamioka * -- * F0 blade prototype test ==== Plan for week of 4/30 ==== * Golden Week! |
==== Report for week of 11/12 ==== * SRM * Hirata-san and Mark craned the LBB ring sandwich to the ceiling of the lower half of the tank, and set the heights of the jacks on the upper half. * Fabian and Hirata-san finished the in-vacuum cabling. * Enzo ran DC power to the second SRM stepper driver and did the rest of the in-air cabling. * We're now ready for final tests of the SF/... items and initial tests of the PI items. * Enzo and Fujii-kun built three geophones for SRM. * Mark worked on the height budget. * SR2 * Enzo experimented with [[http://www2.mpq.mpg.de/~ros/geo600_docu/soft/liso/manual.pdf|LISO]] (circuit analysis software which, among other functions, can fit measured TFs with a ZPK model) but then wrote his own fitting software in Python and used it to build Foton models of key TFs of the SR2.
