| ==== 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 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). |
==== Report for week of 7/30 ==== * ==== Plan for week of 8/6 ==== * Mark, Enzo, Hirata-san, Fabian, Kozu-kun, Terrence, Panwei at Kamioka Mon-Fri. * Kozu-kun works at Mozumi Mon, Fri, and Thu afternoon. |

| * Unlock suspension. * Rearrange cables. * Test. |
* Finalize optic pitch, OSEM alignment. * Do TFs with temporary OL. * Install final OL. * Hook LBB, add ballast mass, set up temporary OL (horizontal beam, pitch/yaw only). |

| * Finish PI prep. * Crane into AF, suspend. * Start cable routing. |
* Add estimated final ballast mass. * Do PI cable routing. * Adjust ballast/trim mass, with reserve for cables. |

| * Prepare to assemble SRM metal mass (most parts due Wed 7/25). * Help Mirapro with AF move. * Start rebuild of top filter of PI #2. |
* Assemble metal mass. * Glue prisms, flags. * Reconfigure, align assembly frame. * Tune F0 for SRM. * Add LBB blade units, cable clamps etc. * Check PI coil connections, IP LVDT magnets. |
