Fermilab
Fermi National Accelerator Laboratory, located just outside Batavia, Illinois, near Chicago, is a United States Department of Energy national laboratory specializing in high-energy particle physics. Since 2007, Fermilab has been operated by the Fermi Research Alliance, a joint venture of the University of Chicago, and the Universities Research Association. Fermilab is a part of the Illinois Technology and Research Corridor. Fermilab's Tevatron was a landmark particle accelerator; until the startup in 2008 of the Large Hadron Collider near Geneva, Switzerland, it was the most powerful particle accelerator in the world, accelerating protons and antiprotons to energies of 980 GeV, and producing proton-proton collisions with energies of up to 1.96 TeV, the first accelerator to reach one "tera-electron-volt" energy. At 3.9 miles, it was the world's fourth-largest particle accelerator in circumference.
