ATLAS Experiment at the LHC

环向大型强子对撞机光谱仪（ATLAS）是一种通用探测器，将充分利用大型强子对撞机（LHC）质子-质子碰撞计划的潜力。 LHC将提供比以前的对撞机高10倍的质心能量和高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组成部分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。 ATLAS将极大地提高分辨能力，用它可以测量物质的组成部分，夸克和轻子的大小。 Z和W粒子的发现是对基本相互作用理解的一大步。 ATLAS将能够发现和测量具有类似性质的粒子，但质量比W和Z大50倍。 ATLAS是专为一个大的发现潜力和精密测量。 探测器的设计是基于广泛的研发合作，并显示出许多创新的功能。 在六年的时间里，逐步增加规模的原型，加上模拟，已被用来优化性能，以满足ATLAS的要求。 来自31个国家的145个研究所的1500名科学家，包括来自28个美国研究所的250名物理学家，将建立和使用ATLAS探测器。 除了探测器协调员外，ATLAS还有一名教育协调员，他与ATLAS教育工作组一起，打算制定一项将研究和教育相结合的重要计划。

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.
