The U.S. ATLAS Operations Program aims to provide U.S. university scientists with access to the uniqueLHC science opportunities through a balanced program that encompasses: (1) the technical effortassociated with maintenance and operation of the U.S.-built detector subsystems, essential in achieving adetailed understanding of the detector for physics results; (2) the maintenance and refinement of software,computing and physics analysis support, critical in allowing scientists at U.S. universities to fully exploitthe physics potential of the LHC, in part through the establishment of university-based Tier 2 computingcenters in the U.S. and the expansion of the existing worldwide grid of resources; (3) an R&D programfor detector upgrades, to maximize the physics output during the long period of running expected for theLHC and maintain U.S. intellectual leadership in accelerator-based particle physics; and (4) a strongeducation and outreach program. The ATLAS collaboration, consisting of 151 institutes from 34countries, is completing construction of the ATLAS detector at the Large Hadron Collider (LHC) atCERN, and preparing for initial data taking in 2007. The 34 institutions of U.S. ATLAS, with the supportof NSF, have made major and unique contributions to the construction of the ATLAS detector, andcontinue to provide critical support for the ATLAS computing and software program, and pre-operationstasks as the detector is commissioned at CERN.Intellectual Merit: The goal of the U.S. ATLAS Operations Program is to empower U.S. physicists toaddress some of the most profound questions in particle physics today: what is the physical origin ofmass? Do supersymmetric particles exist and will they shed light on the nature of dark matter? Doesspace-time have extra spatial dimensions? Answers to these questions would provide a major advancetoward completing a unified view of the particles in nature, the forces with which particles interact, andtheir role in the past and future of our universe. This is a time when particle physics researchers haveunusually compelling indications that the step to be taken by the LHC, leading to collision energies farbeyond those available at existing facilities, will lead to especially important discoveries withimplications over a broad field of fundamental science. This program rests on the especially strongscientific case for investigating the energy regime that will be accessed by the LHC, and benefits from aprogram in which the international community is providing a major part of the investment. The boldinitiative of the NSF, in partnership with the DOE, to carry out a very significant portion of theconstruction and operations of the ATLAS detector has opened up this opportunity for U.S. scientists.Broader Impacts: This proposal will enhance the computing infrastructure for research, education andbeyond. The LHC computing requirements are driving a paradigm shift towards global computing withpotentially significant economic impacts, and our students will be at the forefront in using these newtechnologies. NSF-ATLAS groups continue to expand their education and outreach programs, with aparticular focus on high school teachers and students (closely coordinated with QuarkNet), and onoutreach to under-represented populations. We plan on strengthening and expanding our outreach effortsin the run-up to ATLAS data taking, including plans to help establish a computing center in Africa as partof our expanding network of worldwide grid facilities. This site will provide a platform on which tolaunch a program of Grid-based outreach in Africa. Starting in a few years the LHC will be the majoraccelerator-based program in which to train the next generation of physicists. Support for R&D activitieswill lay the groundwork for new technologies that might be adopted by other fields.

美国地图集运营计划旨在通过一个涵盖的平衡计划为美国大学科学家提供对IniquelHC科学机会的机会：（1）与美国建造的探测器子系统的维护和运作相关的技术努力，对于实现对探测器的物理学结果的Adetail Adetail Adetail至关重要； （2）对软件，计算和物理分析支持的维护和完善，这对于允许美国大学的科学家充分利用LHC的物理潜力，部分是通过建立美国的大学2级计算中心以及现有的全球资源网格的扩展； （3）用于探测器升级的研发计划，以最大程度地提高预期的长期运行期间的物理输出，并在基于加速器的粒子物理学中维持美国的知识领导力； （4）强大的教育和外展计划。由151家来自34个库的机构组成的Atlas合作正在完成ATLAS探测器的建设，该探测器在大型强子对撞机（LHC）ATCERN上完成，并为2007年的最初数据做好准备。美国ATLA的34个机构在NSF上为NSF提供了批判和独特的构建，以构建ATAS ATSIN和CONTERTER ATESTER和CONTERAUD ATETER和CONTETER，并为ATSLAS的构建构建。计划，以及作为检测器作为CERN的委托。智能优点：美国Atlas运营计划的目标是使美国物理学家的能力促进当今粒子物理学中一些最深刻的问题：什么是物理起源？是否存在超对称颗粒，它们会揭示暗物质的性质吗？ Doesspace时间具有额外的空间维度？对这些问题的答案将为您提供一个重大的进步，以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。这是一个粒子物理研究人员，具有令人信服的迹象表明，LHC要采取的步骤，从而导致Farbeyond在现有设施中可用的碰撞能量，这将导致在基本科学广泛领域的象征性发现的尤其重要的发现。该计划基于调查将由LHC访问的能源制度的特别强大的案例，并从国际社会提供了主要投资的主要部分中受益。 NSF的大胆性与DOE合作，在ATLAS探测器的构建和运营中进行了很大一部分，这为美国科学家打开了这一机会。BROADER的影响：该提案将增强研究，教育和Beyond的计算基础设施。 LHC计算的要求正在推动具有重要的经济影响的范式转变向全球计算，我们的学生将在使用这些纽格学方面处于最前沿。 NSF-ATLAS团体继续扩大他们的教育和外展计划，公寓专注于高中教师和学生（与Quarknet密切协调），并遭受了代表性不足的人群。我们计划加强和扩大我们在Atlas数据获取的计划中的推广工作，包括帮助在非洲建立计算中心的计划，这是我们扩展的全球网格设施网络的一部分。该站点将提供一个平台，该平台可以在非洲使用基于网格的外展计划。从几年来开始，LHC将是基于主要速度的计划，其中训练下一代物理学家。对研发活动的支持将为其他领域可能采用的新技术奠定基础。
