ATLAS - Physics on the TeV-scale at the Large Hadron Collider
The ATLAS experiment is one of the four big experiments at the Large Hadron Collider (LHC) at CERN (Geneva, Switzerland). A collaboration of about 3000 scientists from all around the world aims at studying proton - proton collisions at very high energies and particle fluxes. New and exciting particles are to be discovered, deeper insight into the fundamental forces and structures of our universe to be gained. The experiment has been built and installed in Geneva in a joint effort over the last decade, has been thoroughly commissioned, and is capturing collison data since end of 2009.
