The ATLAS experiment at the CERN LHC

Atlas和CERN大型强子对撞机(LHC)的设计目的是直接解决一些最引人注目的科学问题。几十年的实验和理论发展使我们能够理解宇宙演化中的转变，当时大爆炸后几秒内出现了大质量物质的粒子。我们相信，大型强子对撞机上的ATLAS将发现新物理，很可能是新粒子的形式，加拿大在过去15年里进行了大量投资，作为建设这一大规模项目的国际努力的一部分。阿特拉斯已经开始采集数据，预计大型强子对撞机的最高能量将在2009年。所要求的运作资金将使加拿大人能够从我们对ATLAS和大型强子对撞机的投资中获益，并站在研究物质的最基本成分及其相互作用的前沿。

ATLAS and the CERN Large Hadron Collider (LHC) are designed to directly address some of the most compelling questions in science. Decades of experimental and theoretical development have led us to the brink of understanding the transition in the evolution of the universe when particles of massive matter emerged fractions of a second after the big bang. We are confident that new physics, likely in the form of new particles, will be discovered by ATLAS at the LHC, and Canada has made significant investments over the past 15 years as part of the international effort to build this massive project. ATLAS has already started data-taking, and the highest LHC energies are expected in 2009. The operation funds requested will enable Canadians to reap the benefits of our investments in ATLAS and the LHC and to be at the forefront of the investigation of the most basic constituents of matter and their interactions.
