The ATLAS collaboration, consisting of 174 institutions from 38 countries, completed construction of the large multi-purpose ATLAS detector at the Large Hadron Collider (LHC) at CERN and began data collection with colliding beams in 2010. The 44 institutions of U.S. ATLAS, with the support of NSF, made major and unique contributions to the construction and initial operation of the detector, and to the software and computing program development. This is enabling U.S. physicists to contribute significantly to physics analysis and associated publications. The U.S. ATLAS Operations Program aims to provide the necessary technical support for (1) the maintenance and operation of the U.S.-built detector subsystems;(2) the maintenance and ongoing development of software and computing, and (3), an R&D program for detector upgrades to accommodate accelerator performance improvements . Another component of the program is to provide a strong education and outreach effort. Intellectual Merit: The goal of the U.S. ATLAS Operations Program is to empower U.S. physicists to address some of the most profound questions in particle physics today: what is the physical origin of mass? Do supersymmetric particles exist and are they associated with dark matter? Does space-time have extra spatial dimensions? Answers to these questions would provide a major advance toward completing a unified view of the particles in nature, the forces with which particles interact, and their role in the past and future of our universe. This is a time when particle physics researchers have compelling indications that the LHC, with collision energies far beyond those available at existing facilities, will lead to especially important discoveries with implications over a broad field of fundamental science. Broader Impacts: This proposal will enhance the computing infrastructure for research, education and beyond. The LHC computing requirements are driving a paradigm shift towards global computing with potentially significant economic impacts, and our students will be at the forefront in using these new technologies. NSF-ATLAS groups continue to expand their education and outreach programs, with a particular focus on high school teachers and students and on outreach to under-represented populations. We plan on expanding our outreach efforts during ATLAS data taking, including the network of worldwide grid facilities. The LHC is the major accelerator-based program in which the next generation of physicists is being trained. Support for R&D activities will lay the groundwork for new technologies that might be adopted by other fields as well as train our graduate and undergraduate students. For U.S. physicists to be at the forefront of the physics discoveries, it is vital that the U.S. continue to be a leading participant in the scientific operational phase of the experiment.

由来自38个国家的174家机构组成的Atlas合作完成了大型多用途地图集探测器在CERN的大型强子对撞机（LHC）的建设，并于2010年开始与碰撞光束的数据收集。美国ATLAS的44家机构在NSF的支持下，在NSF的支持下，为NSF的支持，对构造和初始构建了构造和最初的操作，并制作了该构造和初始化的操作，并制作了该软件和最初的操作，并制作了该构造和初始化的操作，并制定了该机构的构成和最初的操作，并制作了该机构的工作，并制作了该机构。这使美国物理学家能够为物理分析和相关出版物做出重大贡献。美国地图集运营计划旨在为（1）美国建造的探测器子系统的维护和运营提供必要的技术支持；（2）软件和计算的维护和持续开发，以及（3），用于可容纳加速器性能改进的检测器升级的R＆D计划。该计划的另一个组成部分是提供强大的教育和外展努力。知识分子的优点：美国地图集运营计划的目标是赋予美国物理学家解决当今粒子物理学中一些最深刻的问题：质量的物理起源是什么？是否存在超对称颗粒，它们是否与暗物质相关？时空有额外的空间维度吗？这些问题的答案将为完成自然界中粒子的统一观点，粒子相互作用的力量以及它们在我们宇宙的过去和未来中的作用提供重大进步。这是粒子物理学研究人员具有令人信服的迹象，即LHC的碰撞能量远远超出了现有设施的碰撞能量，这将导致特别重要的发现，并在广泛的基本科学领域中产生影响。更广泛的影响：该建议将增强研究，教育及其他方面的计算基础设施。 LHC计算要求正在推动范式转向全球计算，并具有潜在的经济影响，我们的学生将在使用这些新技术方面处于最前沿。 NSF-ATLAS团体继续扩大他们的教育和推广计划，特别关注高中教师和学生，并关注代表不足的人群。我们计划在Atlas数据获取期间扩大我们的外展工作，包括全球网格设施网络。 LHC是基于加速的主要计划，在该计划中，下一代物理学家正在接受培训。对研发活动的支持将为其他领域可能采用的新技术以及培训我们的毕业生和本科生的新技术奠定基础。为了使美国物理学家处于物理发现的最前沿，至关重要的是，美国继续成为实验科学运营阶段的主要参与者。
