This award addresses the question of the nature of Dark Matter (DM) in the Universe with an experimental direct detection search for Weakly Interactive Massive Particles (WIMPs) using two-phase xenon detectors within the XENON program. This Collaboration is currently at the 100 kg mass scale with the XENON100 experiment at the Gran Sasso Underground Laboratory (LNGS), Italy. The next phase will be a detector at the ton scale (XENON1T) with a sensitivity goal of more than two orders of magnitude better than the current best limits from XENON100, currently the lowest background and largest mass direct detection experiment operating underground. These funds will enable these groups to continue the XENON100 experiment to reach the design sensitivity for the spin-independent cross-section and to study other WIMP interaction scenarios. They plan to take data for at least one continuous year throughout 2011 to search for both spin-independent and spin-dependent DM, for inelastic DM and low mass DM and for an annual modulation signal in the XENON100 data.Broader Impacts: The XENON science, addressing questions about fundamental properties of the Universe, has all the ingredients to captivate the interest and imagination of students and the general public alike. Technical-related work can impact society in a number of ways: liquid xenon imaging detectors and related technologies find applications in several fields outside particle astrophysics, including national security and medical imaging research.

该奖项通过使用XENON程序中的两相XENON检测器进行实验直接检测搜索，以实验性直接检测搜索对宇宙中暗物质的性质（DM）的性质。目前，在意大利的Gran Sasso Underground Laboratory（LNGS）的XENON100实验中，这项合作的量表目前为100公斤。下一阶段将是吨量表（Xenon1t）的检测器，其灵敏度目标比Xenon100的当前最佳限制好两个以上的数量级，目前是目前最低的背景和最大的质量直接检测实验。这些资金将使这些组能够继续进行XENON100实验，以达到独立于自旋的横截面的设计敏感性，并研究其他WIMP相互作用方案。 They plan to take data for at least one continuous year throughout 2011 to search for both spin-independent and spin-dependent DM, for inelastic DM and low mass DM and for an annual modulation signal in the XENON100 data.Broader Impacts: The XENON science, addressing questions about fundamental properties of the Universe, has all the ingredients to captivate the interest and imagination of students and the general public alike.与技术相关的工作可以通过多种方式影响社会：液体氙气探测器和相关技术在粒子天体物理学以外的几个领域中找到了应用，包括国家安全和医学成像研究。
