The ATLAS detector at the Large Hadron Collider housed at CERN near Geneva. ATLAS is a particle physics experiment at the Large Hadron Collider at CERN. Starting in late 2009, the ATLAS detector will search for new discoveries in the head-on collisions of protons of extraordinarily high energy. ATLAS will learn about the basic forces that have shaped our Universe since the beginning of time and that will determine its fate.
