| * Mark analyzed the QPD data from Friday 12/1 and derived matrices to diagonalize the QPD, and calibrate output in µrad. In the process an error in the IM OSEM diagonalization was discovered: the P and Y gains were low by a factor 2. * Mark re-zeroed the QPD after noting the micrometer readings so we can do TFs over the weekend. * We prepared for the SR2 gluing: * We aligned the SR2 in the box with the wedge on the correct side. * We checked that the remachined BS prism holders fit on the PR2 mirror box. * We checked that with Tatsumi-san's support ring, the prisms would go on at the right height. * We checked the new magnet jigs. * We glued ferromagnetic disks in a large number of IM flag tips and flag bases, and in the SR magnet jigs. * We also glued SR magnets in the magnet bases. |

==== 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). (Hirata-san) * Weigh IM (per Fabian's note in the paper log). * Remove L-brackets from bars on IM ring - send for cleaning/remachining. * Setup OL for checking pitch of SR. * Wipe/blow dust off SR2 frame. * Crane IM into frame. |
