This grant will support the development of an improved isolation system that may be suitable for use in an advanced system for the Laser Interferometer Gravitational-Wave Observatory (LIGO). Professor Drever is investigating the feasibility of a magnetic suspension system to isolate future gravitational wave detectors from seismic vibration. The development of such a system, if successful would extend the useful range of LIGO to gravitational wave frequencies much lower than the initial detector under construction. The window for scientific discovery would thereby be greatly enlarged. This project is jointly supported by the Division of Physics and the MPS Office of Multidisciplinary Activities.

这笔赠款将支持开发一种改进的隔离系统，该系统可能适用于激光干涉仪引力波天文台（LIGO）的先进系统。 Drever教授正在研究磁悬浮系统的可行性，以将未来的引力波探测器与地震振动隔离开来。 这样一个系统的开发如果成功，将把LIGO的有用范围扩展到比正在建设的初始探测器低得多的引力波频率。科学发现的窗口将因此大大扩大。 该项目由物理学系和MPS多学科活动办公室共同支持。
