The ATLAS detector is currently under construction for operation at the Large Hadron Collider (LHC) at CERN, Geneva, Switzerland. Extensive studies show that the LHC should be able to elucidate the mechanism of electroweak (EW) symmetry breaking and to study a variety of other topics related to physics at the TeV scale. In particular, a Higgs boson with couplings given by the Standard Model will be observable in several channels over the full range of allowed masses. If supersymmetry is relevant to EW interactions, it will be discovered and the properties of many supersymmetric particles elucidated.This proposal requests support for the research of approximately 250 physicists and engineers from 33 U.S. institutions that comprise the U.S. ATLAS Collaboration. The U.S. ATLAS groups are making major contributions to the construction of the ATLAS detector and have continuing responsibilities for the components they have built as the detector is installed in the experimental cavern and during the commissioning and installation phases. The U.S. ATLAS groups are planning to establish Tier 2 regional computing centers as part of an overall hierarchical grid of ATLAS computing centers spread around the world. The Tier 2 centers, a key component of this proposal, will play a powerful role in allowing U.S. universities to fully exploit the potential of the LHC, and will set an important precedent for future collaboration on large-scale, international projects.The groups continue to expand their education/outreach programs, with a particular focus on high school teachers and students (closely coordinated with QuarkNet) and on outreach to traditionally under-represented populations.

ATLAS探测器目前正在建造中，准备在瑞士日内瓦欧洲核子研究中心的大型强子对撞机(LHC)上运行。广泛的研究表明，大型强子对撞机应该能够在TeV尺度上阐明电弱(EW)对称性破缺的机制，并研究与物理相关的各种其他课题。特别是，标准模型给出的具有耦合的希格斯玻色子将在整个允许质量范围内的几个通道中被观察到。如果超对称性与电子战相互作用有关，它将被发现，许多超对称粒子的性质将被阐明。这项提议要求支持来自33个美国机构的约250名物理学家和工程师的研究，这些机构组成了美国阿特拉斯合作组织。美国阿特拉斯小组正在为ATLAS探测器的建造做出重大贡献，并在探测器安装到实验洞穴以及调试和安装阶段时继续负责他们建造的部件。美国的Atlas集团正计划建立第二级区域计算中心，作为遍布世界各地的ATLAS计算中心整体分层网格的一部分。Tier 2中心是这项提议的关键组成部分，它将在允许美国大学充分开发LHC潜力方面发挥强大作用，并将为未来在大型国际项目上的合作树立重要先例。这些组织继续扩大其教育/外联计划，特别关注高中教师和学生(与QuarkNet密切协调)以及与传统代表性不足的人群的联系。
