Fermilab is the United States' national laboratory for particle physics and accelerator science, established in 1967 and operated under the Department of Energy. Located on a 6,800-acre site in Illinois, it builds and operates particle accelerators and detectors, conducts high-energy physics experiments, and leads major international scientific collaborations.
The laboratory's history includes foundational contributions to particle physics: its Main Ring accelerator was associated with the discovery of the bottom quark, and the Tevatron collider - once the world's highest-energy particle accelerator - with the discovery of the top quark. Current work is centered on neutrino physics, dark matter, and dark energy research. Fermilab hosts what it describes as the world's most powerful neutrino beam and leads the Deep Underground Neutrino Experiment (DUNE), a large-scale international collaboration.
Technical work at Fermilab spans several disciplines:
- Particle accelerator design, construction, and operation
- Particle detector development
- Neutrino physics experiments
- High-performance scientific computing for experimental data analysis
- Research into dark matter and dark energy
Fermilab supports a broad ecosystem of scientists, engineers, and technologists working across fundamental research and the applied systems that enable it. Its international collaborations draw participants from institutions worldwide, making it a hub for global particle physics research as well as a significant employer of specialized scientific and technical talent in the United States.
