ATLAS (A Toroidal LHC ApparatuS) is one of the six particle detector experiments (ALICE, ATLAS, CMS, TOTEM, LHCb, and LHCf) constructed at the Large Hadron Collider (LHC), a new particle accelerator at the European Organization for Nuclear Research (CERN) in Switzerland. ATLAS is 44 metres long and 25 metres in diameter, weighing about 7,000 tonnes. The project is led by Fabiola Gianotti and involves roughly 2,000 scientists and engineers at 165 institutions in 35 countries. The construction was originally scheduled to be completed in June 2007, but was ready and detected its first beam events on 10 September 2008. The experiment is designed to observe phenomena that involve highly massive particles which were not observable using earlier lower-energy accelerators and might shed light on new theories of particle physics beyond the Standard Model.
