摘要
新一代引力波探测器需要前所未有的隔振水平。本文介绍了 Advanced LIGO 中用于支撑干涉仪核心光学元件的隔振与定位平台的最终设计。这个重达五吨、宽两米半的系统在超高真空中运行。它具有串联安装的两级隔振结构。各级相互嵌套以减少整体高度。每一级都在所有平移和旋转方向上提供隔振。该系统配备了一种独特的低噪声相对传感器和惯性传感器组合。主动控制提供从 0.1 Hz 到 30 Hz 的隔振，将平台运动在 1 Hz 处降低至 m/Hz。主动与被动隔振相结合，将平台运动在 10 Hz 处降低至 m/Hz 以下。被动隔振将运动在 100 Hz 处降低至 m/Hz 以下。本文描述了该平台不仅被设计为满足隔振要求，而且还允许为 Advanced LIGO 天文台所需的十五个单元进行建造、测试和调试的过程。
