Fermilab is America's particle physics and accelerator laboratory.

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 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 1,750 employees include scientists and engineers from all around the world. Fermilab collaborates with more than 50 countries on physics experiments based in the United States and elsewhere.

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.

Fermilab's vision and mission

Fermilab is America's particle physics and accelerator laboratory.

Our vision is to solve the mysteries of matter, energy, space and time for the benefit of all. We strive to:

  • lead the world in neutrino science with particle accelerators
  • lead the nation in the development of particle colliders and their use for scientific discovery
  • advance particle physics through measurements of the cosmos

Our mission is to drive discovery by:

  • building and operating world-leading accelerator and detector facilities
  • performing pioneering research with national and global partners
  • developing new technologies for science that support U.S. industrial competitiveness

Learn more about Fermilab

We've created easy-to-understand fact sheets about every facet of the laboratory, including our research, our economic impact, and our environmental and educational efforts. You can also read online versions of several brochures about the laboratory, its work and its place in the global scientific community. Keep up with Fermilab through our two regular publications: the online-only Fermilab Frontiers and our joint magazine with SLAC National Accelerator Laboratory, symmetry.
