==== 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 ==== * 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. ==== 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 === |
