caption_attribution_description: ATLAS detector being assebled in CERN Deutsch: ATLAS Kaverne, Oktober 2004
context_page_description: ATLAS is the biggest experiment at the Large Hadron Collider.
  It is one of the seven particle detector experiments built at the LHC. LHC is a new particle accelerator at the European Organization for Nuclear Research in Switzerland. ATLAS is 46 metres long and 25 metres in diameter, weighing about 7,000 tonnes. The project is led by Fabiola Gianotti. The project has 2,000 scientists and engineers at 165 institutions in 35 countries. The project began operation on 10 September 2008. ATLAS studies highly massive particles which could not be studied using earlier lower-energy accelerators. ATLAS may start new theories of particle physics beyond the Standard Model.
