 * Split SRx real-time models?
Line 47: Line 95:
==== 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. -> 至急確認



=== 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
