| ==== Past week report ==== At Kamioka (Mark, Ohishi-san, Enzo, Yoshioka-kun, Kozu-kun): * We finished installing the RM OSEMs and installed the new Type5-2.2 and 5-2.4 OSEM cables. * We hung the RM and set its pitch. * We doubled-checked the BS and RM pitch, tightened the clamps and removed the winch system. * We installed the bottom section of the security structure to protect the RM/BS. * We lifted the IM/RM/BS section and weighed it. It was about 1.25 kg too heavy for the new BF, so we improvised a lighter set of ballast masses. * We installed the section of the security structure up to the BF ring, and the BF crossbars and jacks of the assembly frame. * We brought in the new BF. * We installed the BF-IRM rods and IRM top plate. * We reinstalled the IM flags and other items that had been taken off to use the winch system. * We hooked the BF-IM rod (with hex cable clamp). (We did not unlock the BF keystone.) * We cabled and tested the IM-PIT, IM-ROL and IM-YAW picos and the BF FR stepper (but not, yet, the BF LVDT). |
==== 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. |
