| * Type B Past Week Summary * Fabian, Mark and Liu-kun did BS installation at Kamioka: * Debugged the issue with the BF keystone being tilted enough to cause rubbing on the yoke for the magnets. It was solved by moving the yoke ≈1 mm taking advantage of the oversized holes. * Measured the height of the payload as a function of trim mass. The BF spring seems to have a slightly lower load capacity and a rather higher spring constant than when it was remeasured by Hirata-san. * Removed IM trim mass to set the average height of the keystone to the CAD value. * Moved IM trim mass around to set the pitch of the dummy BS. * Hirata-san * TBD. |
=== Type B (Mark) === ==== Report for week of 1/29 ==== * Mark made two sets of in-air pico splitter cables (each with a triple for IM and a double for BF) for SR2 and SR3. * Fabian, Hirata-san and Kozu-kun worked on cabling and testing the IM pitch/roll/yaw picos, the BF FR and the BF LVDT. The LVDT connections were initially unreliable and Hirata-san had to redo the pins on the coil wires. * Fabian installed ballast masses in the BF. * Mark worked on schedule. * Mark did inventory of the stepper motor drivers (many were not accounted for on the wiki and/or JGWDoc and one is missing) and reserved two for SR3. * We emptied out the external cleanroom in preparation for installing SS sheet. ==== Plan for week of 2/13 ==== * No work Monday (建国記念の日の振替休日) * Enzo on vacation * Hirata-san at Mitaka Tue (self-evaluation interview). * Shoda-san at Mitaka. * All others at Kamioka. * - * Build IRM around IM. * Cable/test/adjust IM OSEMs. * Do TFs from IM OSEMs to IM OSEMs, OL pitch/yaw. ==== Plan for week of 2/19 ==== * Enzo back from Tuesday. * Shoda-san at Mitaka. * Hirata-san at Mitaka Mon+Tue (to receive and wash parts). * All others at Kamioka. * - * Lift BF/... section and check total mass and balance. * Cable and test BF picos. * Add section of SS up to SF ring. * Bring in SF. * Hook BF/... section. * Route cables up to under SF. * Check/adjust total mass of BF/... section. ==== Plan for week of 2/26 ==== * Shoda-san at Mitaka. * - * Add Cu segments to SF cap. * Lift SF/... section and check total mass and balance. ==== Vacation Info ==== * Enzo 1/30-2/19. * Fabian 4/2-4/27 vacation (then gone). |
