== SR Prep Tasks ==
=== Design/Purchasing ===
 * Do rough mass budget for SR2/SR3/SRM.
 * Design SR assembly frame.
 * Design final SF ballast masses (Fabian).
==== Order now ====
 * Bread boards for SR -> すぐ見積り依頼
 * Include installation work in the contract
 * Total budget = 5MJPY
 * PEEK collet for "Small hexagon"(cable clamp) -> すぐ見積り依頼

==== Need simple design changes ====
 * SUS wires(3 types) for the LBB
  * Change the length -> すぐ見積り依頼
 * 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
 * SR assembly frame -> 月曜日に見積り依頼
  * 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. -> 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
== SR Prep Tasks - To Be Scheduled ==
=== Tunnel ===
 * Make three in-air stepper splitter cables for SR2, SR3 and SRM. [done?]
 * (Continue to) soak the sapphire prisms off the dummy BS for reuse on the SRM metal mass.
 * Get SRM mushroom installed.
 * Install first set of LBB damper rings in SR2 (or SR3?) tank.
 * Set up SR2 Guardian.
 * Install damping filters for SR2.
 * Make three in-air stepper splitter cables for SR2, SR3 and SRM. [done?]
 * Do buoyancy calculation (see LIGO-T1100616).
 * Set up SR2 Guardian.
 * Install damping filters for SR2.
 * Review Shoda-san's Guardian.
 * Review DIO stuff.
 * Review DAC channel requests.
 * Order Cu O-rings for geophone.
 * Finish half-completed geophones.
 * Find fourth feedthrough for SR2, 8 more for SR3 and SRM.
 * Characterize top filter prototype blades.
 * Decide final top filter blade parameters and order.
 * Rebuild three top filters.
 * Do buoyancy calculation (see LIGO-T1100616).
