Line 57: Line 71:

==== 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
