This award supports Stanford?s ongoing program on advanced gravitational wave detectors. The research will focus on continuing projects on the development and testing of the Advanced LIGO seismic isolation and control systems and on the investigation of improved sensors for increasing performance of active isolation systems. In addition, research will continue on the use of ultraviolet light to mitigate the buildup of electrostatic charges on Advanced LIGO mirrors and on the evaluation of thermalized optical losses in core optic materials and optical coatings. All these efforts have as their goal the increased performance of Advanced LIGO. Gravitational waves were predicted almost 90 years ago in Einstein's General Theory of Relativity, but they have not yet been detected due to the extreme sensitivity required. Interacting black holes, coalescing compact binary stellar systems, stellar collapses, pulsars and low mass X-ray binaries are all possible sources of gravitational waves, as is the random background of radiation from the early universe. Laser interferometer detectors, which operate by measuring strains in the fabric of space-time that are expected to be produced by gravitational waves, are now becoming operational and may soon give us a first detection. Detectors of higher performance, such as Advanced LIGO, should allow us to develop gravitational wave astronomy as a new window on the Universe. Stanford has a strong, multidisciplinary program in developing the technology for such detectors with participants from many areas of physics and engineering. The program provides training for future scientists and engineers at both the undergraduate and graduate levels, it integrates basic scientific research with scientific education, and includes outreach programs that inform and educate the broader community.

这个奖项支持斯坦福大学？正在进行的先进引力波探测器计划。该研究将侧重于先进LIGO地震隔离和控制系统的开发和测试以及改进传感器以提高主动隔离系统性能的研究。此外，还将继续研究使用紫外光来减轻高级LIGO反射镜上静电荷的积累，以及评估核心光学材料和光学涂层中的热化光学损失。所有这些努力都是为了提高Advanced LIGO的性能。引力波在大约90年前就在爱因斯坦的广义相对论中被预测到了，但由于所需的极端灵敏度，它们尚未被探测到。相互作用的黑洞、合并的致密双星系统、恒星坍缩、双星和低质量X射线双星都可能是引力波的来源，早期宇宙辐射的随机背景也是如此。激光干涉仪探测器通过测量时空结构中预计由引力波产生的应变来工作，现在正在投入使用，可能很快就会给我们带来第一次探测。更高性能的探测器，如先进的LIGO，应该使我们能够发展引力波天文学，作为宇宙的一个新窗口。斯坦福大学有一个强大的，多学科的计划，在开发这种探测器的技术与参与者来自许多领域的物理和工程。该计划为未来的科学家和工程师提供本科和研究生水平的培训，它将基础科研与科学教育相结合，并包括宣传和教育更广泛社区的推广计划。
