== 2017-12-11 == * Double check prism heights. * Do mirror gluing. * Assemble SR2 IP. * Set up for testing IP with BS pico driver. * Make pico cable. * Assemble IP. * Test IP picos. * Weigh BF. * Find accessories. * Do weighing. * Find in-vac cables: * 2 x Type 3-6m * 1 x Type 3-2m * 4 x Type 4-1.5m * 5 x Type 1-2m * 7 x Type 2-2m * Set up SR2 rack * Get ADC/DAC/DIO cards. (Done?) * Hassle Miyo-kun for pico and stepper drivers. * Get Miyakawa/Yamamoto to connect rack to DC power, Internet, etc. * Get cables/cards for SR2. (Done?) * Find and attach feedthroughs. * Adjust verticality of assembly frame; center and immobilize optical table. |

* Install new jack receptacles (in SR3 area, second floor) on load gauge adapter (SR2 area, second floor). * Finish mass budget for SR2/SR3/SRM (Fabian) - mostly done. * Design final SF ballast masses (Fabian). * Get safety bars moved. * Get air hose connection moved. === Design/Purchasing === * Lots of stuff - see Hirata-san's spreadsheet. ==== 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 === |
=== 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). |
