==== Report for week of 2/26 ==== * We routed all the cables from the BF level up via the flying saucer to the SF. * Hirata-san tried filing the SF cap to improve the fit, but without much success. * Hirata-san installed the Cu segments and cable clamps on the SF cap and the SF LVDT and FR cables. * We cabled and tested the BF cap picos and the SF LVDT and FR. (The LVDT still needs a full calibration.) * We worked on recovering the IM OSEM alignment. |
==== Report for week of 7/17 ==== * We checked the polarity of the IP LVDTs and flipped coil connections to get the standard arrangement. * We debugged an issue where one of the LVDT actuators had half the magnets in backwards resulting in no force. * We calibrated all the PI LVDTs. * We set the SF damper ring gap. * We prepped the suspension for craning, moved it into the tank and hooked the LBB damper ring rods. * Type A merged the SRM F0 with the correct IP, and we moved it out of the way (to the second floor behind the SRM tank). * We installed more cable clamps on the SR2 PI. |

==== Plan for week of 2/26 ==== * Shoda-san at Mitaka. * - * Enzo at Mitaka Mon 2/26. * '''Remove LBB temporary ballast masses from BS chamber.''' * Route cables up to under SF. * Check/adjust total mass and balance of BF/... section, especially IM OSEMs. * Cable and calibrate SF LVDT. * Add Cu segments to SF cap. * Install cap. * Lift SF/... section and check total mass and balance. |
==== Plan for week of 7/23 ==== * Mark, Enzo, Fabian, Kozu-kun, Terrence, Panwei at Kamioka Mon-Fri. * Hirata-san at Kamioka Mon-Thu. * Mirapro moves assembly frame ≈7/25 (Wed). |
