The Tevatron is a particle accelerator operated at the Fermi National Accelerator Laboratory in Batavia, Illinois. Since the completion of construction in 1983, the Tevatron has accelerated counterpropagating beams of protons and antiprotons in a 6.28 kN diameter synchrotron ring. Many important aspects of the Standard Model were supported by Tevatron experiments. Notably, the top quark was first discovered in Tevatron collisions. The Tevatron is the most powerful proton-antiproton collider in the world, with collision energies of up to 2 TeV. Only the LHC, a proton-proton collider, is capable of creating higher energy collisions.
