| * Hirata-san: * Worked on the PR optic removal jig. * Worked on getting modified quotes for PR/SR/BS parts. * Enzo-san * Worked on getting his drivers license. * Worked on getting familiar with the Type B circuit diagram. * Mark, Fabian (at Kamioka): * Tried different strategies for getting the IRM-IM EQ stops and IRM OSEMs to line up simultaneously. * Realized that the main problem was that the pitch of the BS had changed relative to the IM (presumably due to slight slippage of the wires) so the IM had to be pitched up by 16 mrad to get the BS pitched slightly down (4.7 mrad). * Took the sides off the IRM to get access to the clamps and tightened them to prevent further slips. * Rebalanced the IM to be level in pitch (and roll). * Reassembled the IRM and aligned the IRM-IM EQ stops - this time it was easy. * Adjusted the IRM and RM OSEMs to mid-range. * Got Kokeyama's new real-time model working and started TFs. ==== Plan for coming weeks ==== * Mark and Enzo come to Kamioka and work on rack and cabling. * Fabian works on design, including SR assembly frame. * Hirata-san works on procurement. |
* Mark created screens and a macro.txt file for the SR2 and linked to them from the VIS screen. * Enzo and Mark did a new overview screen for the BS. * Enzo added DIO cards to the rack and connected them to the coil drivers. * Fabian and Kozu-kun finished assembling the IM and tested the picos over their full range. * Mark and Hirata-san configured and aligned the assembly frame and optical table and craned in the IM ring. * Hirata-san noticed some oxidization on several of the L-brackets that will hold the IM horizontally, and we should get them cleaned or machined, but we can probably continue with hanging the system in the meantime. ==== Plan for week of 12/25 ==== * Power outage 12/25. * Mark, Enzo, Fabian vacation * Shoda-san, Kozu-kun, Hirata-san at Kamioka - Hirata-san from Tue, others TBD. * Recover after power outage. * Create SR2 real-time model. * Install new jack receptacles (in SR3 area, second floor) on load gauge adapter (SR2 area, second floor).
