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. |
