The ATLAS Experiment

ATLAS is one of two giant multi-purpose detectors at the Large Hadron Collider (LHC) of CERN, and the largest volume particle detector ever constructed. It measures 46 m long, 25 m high and 25 m wide, and weighs over 7000 tons. The collaboration consists of over 2500 physicists from 39 countries, and will investigate a wide range of physics, including the search for the Higgs boson, extra dimensions, and particles that could make up dark matter.
