Einstein's General Theory of Relativity (GR) predicts that dynamical systems in strong gravitational fields will release vast amounts of energy in the form of gravitational radiation. Gravitational waves are ripples in the fabric of spacetime and travel from their sources at the speed of light, carrying information about physical processes responsible for their emission, obtainable in no other way. They are among the most elusive signals from the deepest reaches in the Universe. Experiments aimed at detecting them have been in development for several decades, and are now reaching sensitivity levels where detection is expected within a few years.The worldwide network of interferometric detectors includes the German-UK GEO600, the French-Italian Virgo, the American Laser Interferometer Gravitational-Wave Observatory (LIGO) and is being enhanced with a new detector under construction - KAGRA in Japan. The former detectors have all reached sensitivities close to their design goals and have taken the most sensitive data to date. Cooperation amongst different projects enables continuous data acquisition, with sensitivity to a wide range of sources and phenomena, over most of the sky.Data from GEO, LIGO and Virgo, have already increased our understanding of astronomical phenomena. Search for gravitational waves at the times of 154 gamma-ray bursts has allowed the best ever exclusion distances and provided evidence for extra-Galactic sources of soft-gamma repeaters. The distance reach for binary black holes in the most recent runs is 300 Mpc and the rate upper limits are now very close to that expected in some of the astrophysical models. The search for gravitational waves from the Vela pulsar has set an upper bound on the strength of radiation that is significantly below that expected from the observed spin down rate of the pulsar, corresponding to a limit on the star's ellipticity of a part in a thousand. This proposal for equipment will support the experimental programme of detector research and development supported by our Consolidated Grant ST/L000946/1. Detector sensitivity is mainly limited by thermal noise associated with the substrates of the mirrors, their reflective coatings, and their suspension elements, as well as by noise resulting from the quantum nature of the light used in sensing. Our research is targeted towards making innovative improvements in these areas. We have major responsibilities for the silica suspensions in aLIGO, and in the development of enhancements and upgrades to the aLIGO detectors, in the areas of mirror coatings for low thermal noise, silicon substrates, cryogenic suspensions and improved interferometer topologies to combat quantum noise.

爱因斯坦的相对论一般理论（GR）预测，强力引力场中的动力系统将以引力辐射的形式释放大量能量。引力波在时空的结构中是涟漪，并以光速从其来源传播，携带有关其发射的物理过程的信息，无法以其他方式获得。它们是宇宙中最深处的最难以捉摸的信号之一。 Experiments aimed at detecting them have been in development for several decades, and are now reaching sensitivity levels where detection is expected within a few years.The worldwide network of interferometric detectors includes the German-UK GEO600, the French-Italian Virgo, the American Laser Interferometer Gravitational-Wave Observatory (LIGO) and is being enhanced with a new detector under construction - KAGRA in Japan.前探测器都达到了接近其设计目标的敏感性，并采用了迄今为止最敏感的数据。在不同项目之间的合作可以使数据获取不断获取，对大多数天空的敏感性，对广泛的来源和现象的敏感。在154个伽马射线爆发的时代，搜索引力波已经允许有史以来最好的排除距离，并为软伽玛中继器的半乳酸来源提供了证据。在最近的运行中，二进制黑洞的距离为300 MPC，现在在某些天体物理模型中，速率上限非常接近预期。从Vela Pulsar的引力波的搜索已经建立了辐射强度的上限，这显​​着低于观察到的脉冲星的旋转速度的预期，这对应于一千颗零件零件零件的椭圆度的限制。该设备提案将支持我们合并的赠款ST/L000946/1支持的探测器研发实验计划。检测器灵敏度主要受热噪声，与镜子的底物，反射涂层以及它们的悬浮元素以及噪声相关的热噪声限制，以及由传感中使用的光的量子性质产生的噪声。我们的研究旨在在这些领域进行创新的改进。我们对阿里戈（Aligo）的二氧化硅悬浮液以及对艾利戈探测器的增强和升级，在镜像涂料的区域的发展和升级方面负有主要责任，以进行低热噪声，硅基底物，低温悬浮液和改善的干涉仪拓扑，以打击量子噪声。
