ATLAS is the largest general-purpose <a href="/facts/Particle_detector/rYj0qKtA">particle detector</a> experiment at the <a href="/facts/Large_Hadron_Collider/XWJCFSqT">Large Hadron Collider</a> (LHC), a <a href="/facts/Particle_accelerator/Pkuc08xC">particle accelerator</a> at <a href="/facts/CERN/y1gwRchm">CERN</a> (the European Organization for Nuclear Research) in Switzerland. The experiment is designed to take advantage of the unprecedented energy available at the LHC and observe phenomena that involve highly massive <a href="/facts/Elementary_particle/CTFDM97U">particles</a> which were not observable using earlier lower-<a href="/facts/Energy/wd8PrQM7">energy</a> accelerators. ATLAS was one of the two LHC experiments involved in the discovery of the <a href="/facts/Higgs_boson/3LAYXfft">Higgs boson</a> in July 2012. It was also designed to search for evidence of <a href="/facts/Theories/9vrNS1Rr">theories</a> of <a href="/facts/Particle_physics/YgIuyj2t">particle physics</a> beyond the <a href="/facts/Standard_Model/LhVGf9ow">Standard Model</a>.
</p><p>The experiment is a collaboration involving 6,003 members, out of which 3,822 are <a href="/facts/Physicist/cQcgvSIm">physicists</a> (last update: June 26, 2022) from 243 institutions in 40 countries.
