Fermi National Accelerator Laboratory

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; at 3.9mi in circumference, it was the world's fourth-largest particle accelerator, until it was shut down in 2011. In 1995, the discovery of the top quark was announced by researchers who used the Tevatron's CDF and DØ detectors.
