| ==== 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. |
==== Report for week of 4/9 ==== * Mark glued prisms and magnet/standoff assemblies on the SR3. The SR3 needed to be raised in the box by 0.7 mm to make the prisms go on at the right height, which was done using M4 washers under the PEEK feet. * Mark glued ferromagnetic disks on the last 5 IM flags. This completes 2 sets, for SR3 and SRM. * Mark configured two pico motor drivers ordered by Takahashi-san as SR3-IM and SRM-BF. * Enzo and Kozu-kun finished preparing and calibrating the SF and BF for SR3 and almost entirely finished with those for SRM. * Hirata-san worked on building two IMs for SR3 and SRM. The SR3 one just needs to have flags attached and to be weighed; the SRM needs another few hours work. * Shoda-san worked on the design of the metal SRM, on the LBB ballast mass, and on the plans for testing the BS in bKAGRA Phase 1. |
