==== Past week report ==== At Kamioka (Mark, Fabian, Enzo, Hirata-san): * Hirata-san published his inventory of SR parts on Dropbox. * Mark and Enzo finalized the geometry matrices for the IP, entered them in MEDM and updated the safe.snap. * Mark, Enzo and Fabian worked with Izumi-san et al. to align the BS. We got the +Y beam fairly close to aligned (to the second gate valve, near IY). |
==== 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. |
