A Toroidal Large Apertune Spectrometer (ATLAS) is a general-purpose detector that will exploit the full potential of the Large Hadron Collider (LHC) proton-proton collision program. The LHC will provide 10 times higher center-of-mass energy and 1000 times higher proton-proton collision rates than previous colliders. This opens up new frontiers of physics which ATLAS will explore. The Standard Model, which is the established theoretical description of the basic building blocks of matter and of the fundamental interactions, has several unexplored aspects, all well within the reach of ATLAS. ATLAS will greatly increase the resolving power with which the size of the building blocks of matter, the quarks and leptons, can be measured. The discovery of the Z and W particles was a large step forward in the understanding of fundamental interactions. ATLAS will be able to discover and measure particles with similar properties but with masses up to 50 times larger than those of the W and Z. ATLAS is designed for a large discovery potential and for precision measurements. The detector designs are based on extensive R&D within the collaboration and display many innovative features. Over a period of six years, prototypes of progressively increasing scale, together with simulations, have been used to optimize the performance to meet the ATLAS requirements. An international collaboration of 1500 scientists, from 145 institutes in 31 countries, including 250 physicists from 28 US institutions, will construct and use the ATLAS detector. ATLAS has, in addition to detector coordinators, an education coordinator who, with an ATLAS education task group, intends to develop a significant program integrating research and education.

环面大口径光谱仪(ATLAS)是一种通用探测器，它将充分利用大型强子对撞机(LHC)质子-质子碰撞计划的全部潜力。大型强子对撞机将提供比以前的对撞机高10倍的质心能量和1000倍的质子-质子碰撞率。这开辟了ATLAS将探索的物理学新领域。标准模型是对物质的基本构件和基本相互作用的既定理论描述，它有几个未探索的方面，都在ATLAS的范围内。阿特拉斯将极大地提高分辨率，用来测量构成物质的块--夸克和轻子--的大小。Z粒子和W粒子的发现在理解基本相互作用方面向前迈进了一大步。ATLAS将能够发现和测量具有类似性质但质量比W和Z大50倍的粒子。ATLAS的设计目的是为了更大的发现潜力和精确测量。探测器的设计基于合作中的广泛研发，并展示了许多创新功能。在六年的时间里，逐步扩大规模的原型与模拟一起被用于优化性能，以满足ATLAS的要求。由来自31个国家的145个研究所的1500名科学家组成的国际合作将建造和使用ATLAS探测器，其中包括来自28个美国机构的250名物理学家。除了探测器协调员外，阿特拉斯还有一名教育协调员，他与ATLAS教育工作组一起，打算制定一项整合研究和教育的重要计划。
