The Fermilab particle accelerator complex provides beam to numerous experiments and test stations. The accelerators can make beams of protons, neutrinos, muons, and other particles. The two-mile Main Injector makes the world's most intense high-energy neutrino beam. (Photographer: Reidar Hahn)

Fermilab is America's particle physics and accelerator laboratory. Founded in 1967, Fermilab drives discovery by investigating the smallest building blocks of matter using world-leading particle accelerator and detector facilities. We also use the universe as a laboratory, making measurements of the cosmos to the mysteries of dark matter and dark energy. Fermilab is located near Chicago, Illinois, and is managed by Fermi Research Alliance, LLC for the U.S. Department of Energy Office of Science.

What are we made of? How did the universe begin? What secrets do the smallest, most elemental particles of matter hold, and how can they help us understand the intricacies of space and time?

Since 1967, Fermilab has worked to answer these and other fundamental questions and enhance our understanding of everything we see around us. As the United States' premier particle physics laboratory, we do science that matters. We work together with our international partners on the world's most advanced particle accelerators and dig down to the smallest building blocks of matter. We also probe the farthest reaches of the universe, seeking out the nature of dark matter and dark energy.

Fermilab's 6,800-acre site is located in Batavia, Illinois, and is managed by the Fermi Research Alliance LLC for the U.S. Department of Energy Office of Science. FRA is a partnership of the University of Chicago and Universities Research Association Inc., a consortium of 89 research universities.
