== 2017-11-27 == * Bring racks from SRM area. * Find mirror gluing items. * Mirror * Mirror box * Prism micrometer stages * Prism jigs * Lenses for inspecting scribe lines * Procedure document. * Rehearse mirror gluing. * Assemble SR2 IP. * Set up for testing IP with BS pico driver. * Make pico cable. * Assemble IP. * Test IP picos. * Adjust verticality of assembly frame; center and immobilize optical table. * Add L-brackets to new whitening filter and two HPCDs (one in BS rack). * Move SR2 rack into position. * Run cables to assembly frame. * Find and attach feedthroughs. * Install new jack receptacles on load gauge adapter. |
==== Plan for week of 4/23 ==== * Clean parts (cable clamp bases, etc, etc; Hirata-san). * Observe KAGRA Phase 1 operations, assist if problems arise. * Continue SR3 hang. |

=== Design/Purchasing === ==== Order now ==== * Bread boards for SR -> Orderd. delivery date:10/18-20 * Include installation work in the contract * Total budget = 5MJPY * PEEK collet for "Small hexagon"(cable clamp) -> need modification. ==== Need simple design changes ==== * SUS wires(3 types) for the LBB * Change the length -> Orderd. delivery date:10/ * Receptacles for Bread board damper * There is a mistake in the PROMEC drawing. * Hirata-san will make a new 2D drawing * IM wire clamps for SR * Need to change the height -> watiting second quote. * SR assembly frame -> Ordered. delivery date:9/27-29 * Mark is checking the design from Fabian * We should order the parts necessary to modify the BS assembly frame to the SR2 assembly frame ==== Need Fabian's input ==== * Cable clamps for BF,SF and PI -> 方式を決める * Design change for the PI clamps, because the SR PIs are NIKHEF ones. * Ballast masses for BF and SF * 製作に2週間程度 * 10月頭にTop Filterの最適荷重を実測。それに合わせて発注。それまでにデザインは用意しておく。 * 測定に必要な物品の準備 -> 月曜日に高橋さんと相談 ==== Need more discussion/checks ==== * Blade spring assembly for LBB * Check the load of the LBB and decide the design load of the springs * Correct the length * Scale the width of the current blades to design the new blades -> 高橋さんと相談 * SR用LBBの重さを確認 * Bread board damper rings * Need to check whether we can put a full ring into the chamber from the side flanges or not. -> need modification === Electronics === * Get cables/cards for SR3: * 5 DSub-37 cables (tent) * 5 DSub-15M to DSub-9M adapter cables (tent) * 3 DIO cards (tent) * 2 DSub-9 FF gender benders (for LVDTs) * extra ADC card(s)? * extra DAC card(s)? * BNC-LEMO adapter (for LVDTs) * etc |
* Glue SR3. * Disassemble two top filters. * Rebuild three top filters. |
