46°14′8″N 6°3′19″E / 46.23556°N 6.05528°E / 46.23556; 6.05528 ATLAS[1][2][3] is the largest general-purpose particle detector experiment at the Large Hadron Collider (LHC), a particle accelerator at CERN (the European Organization for Nuclear Research) in Switzerland.[4] The experiment is designed to take advantage of the unprecedented energy available at the LHC and observe phenomena that involve highly massive particles which were not observable using earlier lower-energy accelerators. ATLAS was one of the two LHC experiments involved in the discovery of the Higgs boson in July 2012.[5][6] It was also designed to search for evidence of theories of particle physics beyond the Standard Model.

The experiment is a collaboration involving 6,003 members, out of which 3,822 are physicists (last update: June 26, 2022) from 257 institutions in 42 countries.[1][7]
