| * Hirata-san: * Updated the 3D assembly model for BS (among other issues, it turned out that parts were not correctly mated near where the suspension sits on the hydraulic jacks in the tank). * Liaised with IJECT. * Made an inventory for Type B (BS and SR). * Packed and shipped second winch to Kamioka. * Packed some jigs for adjusting BF blades. * Attended NINS information security seminar. * Attended the public hearing for the Opt-IR Research Division Chief Election. * Mark, Fabian, Enzo * Cabled IM picos and used IM yaw pico for adjusting RM. (Later, a wire broke at the connector, disabling the IM yaw, but we were able to continue by manually rotting the pic.) * Helped Takahashi-san in adjusting BF. * Initial round of adjustment made transverse perfect but overshot in longitudinal and made vertical unstable. * Second round of adjustment made vertical stable but left longitudinal offset. * Concluded that we can probably manage without bringing the BF back to Mitaka, but it will take some careful surveying of the existing offset and several more days of adjustment. |
=== Type B (Mark) === ==== Past week report ==== At Kamioka (Mark, Fabian, Enzo, Hirata-san): * Hirata-san did an inventory of SR and other parts at Kamioka. * 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). ==== Plan for week of 10/30 ==== Kamioka: Mark and Enzo * Continue alignment of BS. * Realign OL. * Work on servos. Mitaka: Fabian and Hirata-san * SR procurement. * New PI GAS FR design. * BS LBB ballast mass design. * SR cable lamp design. |
