The principal investigator will continue his research to investigate new techniques to improve the sensitivity of gravitational wave detectors. The thrust of the effort is to explore isolation systems with low frequency performance superior to those currently in use. These developments have application in the NSF supported Laser Interferometer Gravitational- Wave Observatory.Three areas will be pursued: the magnetic levitation of test masses, the suspension point interferometer, and the use of paramagnetic materials for test masses. These developments may be expected to mature five to ten years from now and could have important applications in future versions of LIGO.

首席研究员将继续他的研究，研究新技术，以提高引力波探测器的灵敏度。 努力的重点是探索低频性能上级目前使用的隔振系统。 这些发展在NSF支持的激光干涉仪引力波天文台中得到了应用。将研究三个领域：试验质量的磁悬浮、悬点干涉仪和试验质量的顺磁材料的使用。 这些发展可能会在五到十年后成熟，并可能在未来的LIGO版本中有重要的应用。
