This project will create a full scale facility for testing optical aberration correction schemes for the world's gravitational wave detectors. The optical surfaces in gravitational wave detectors must be controlled to the atomic level to limit the impact of quantum noise and maximize the sensitivity of these extraordinary instruments. The fine tuning of optical surfaces is done using the so-called thermal compensation systems and currently the performance of these systems can only be evaluated once they are installed on a gravitational wave detector. This is severely limiting the optimization of this critical sub-system and hence there is an urgent need for this facility because it will be the only one of its type anywhere on the globe.

该项目将建立一个全尺寸的设施，用于测试世界引力波探测器的光学像差校正方案。引力波探测器的光学表面必须控制在原子水平，以限制量子噪声的影响，并最大限度地提高这些非凡仪器的灵敏度。光学表面的微调是使用所谓的热补偿系统完成的，目前这些系统的性能只能在安装在引力波探测器上后才能进行评估。这严重限制了这一关键子系统的优化，因此迫切需要这一设施，因为它将是地球仪上唯一的一个此类设施。
