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.
