==== Past week report ==== At Kamioka (Mark, Fabian, Hirata-san, Yoshioka-kun): * We reconfigured the top of the assembly frame. * We cleaned the assembly frame, blowing dust out of the grooves and wiping all surfaces. * We recentered the optic table in the bottom of the frame and adjusted the frame until the top was centered over the optic table. We also recentered the trolleys. * We re-installed, centered and leveled the IM. * We solved two issues with the new wire clamps: * Some holes were not properly threaded - Hirata-san retapped them. * Some locating pins were loose - we glued them. * We mounted the BS mirror box on the trolley and brought it under the IM. * We installed the winch system and the 300 µm wires for the BS. * We set up the optical lever. * Hirata-san finished the new BF. We moved the old BF out of the cleanbooth and the new one in. * We suspended the BS and set its height and pitch. |
==== Report for week of 12/25 ==== * Hirata-san got the L-brackets machined and washed, and installed them on the IM ring bars. * Shoda-san recovered the BS from the power outage on 12/25. * Miyakawa-san fixed an issue with the SR2 RTM which had prevented it from running. * Shoda-san, Hirata-san and Kozu-kun weighed the IM without ballast masses, and then added the lower masses and installed the IM on the assembly frame. * They cleaned the assembly frame and installed new jack receptacles on the load gauge adapter. * They installed the winch system on the IM, and inspected the clamp pieces for possible scratches. * They ran cables for the SR2 steppers and OSEMs. * They calibrated the BF LVDT. |
