In January 2007, the Large Hadron Collider - LHC - will start proton-proton collisions at unprecedent high energies of 14 TeV. The ATLAS experiment will record the products of the collisions. The analyses of the data will reveal new insights into the fundamental buildings blocks of nature and the fundamental forces between them. The focus of this project is the preparation of the analyses based on simulations, and starting in 2007, real data analyses, in particular studies of the top quark, the search for the Higgs Boson, and the search for Dark Matter. The mystery of dark matter is the fact that measurements of the cosmic microwave background have shown that only 5% of matter, necessary for the development of the Universe, come in the form of ordinary, visible matter. The nature of the remaining 95% is unknown and will be investigated. In Munich a computer centre will be setup, which will be integrated into the newly developed worldwide computer grid, a crucial prerequisite for the above mentioned data analyses. This new technology allows data analysis in a few hours instead of several hundred years.

2007年1月，大型强子对撞机-LHC-将以前所未有的14TeV高能开始质子-质子碰撞。ATLAS实验将记录碰撞的产物。对数据的分析将揭示对自然界的基本建筑以及它们之间的基本作用力的新见解。该项目的重点是准备基于模拟的分析，并从2007年开始进行实际数据分析，特别是对顶夸克、希格斯玻色子和暗物质的研究。暗物质的奥秘在于，对宇宙微波背景的测量表明，宇宙发展所必需的物质中，只有5%是普通的、可见的物质。其余95%的人的性质尚不清楚，将进行调查。将在慕尼黑建立一个计算机中心，该中心将纳入新开发的全球计算机网格，这是上述数据分析的关键先决条件。这项新技术可以在几个小时内进行数据分析，而不是几百年。
