Facilities and Experiments
The Office of High Energy Physics (HEP) supports particle physics experiments at accelerators, underground laboratories, space exploration missions and ground-based telescopes. These experiments present new opportunities for discovery at the three frontiers of particle physics. When combined, these different pathways of discovery lead to one complete picture of the fundamental nature of the universe.
Experiments at the Energy FrontierThe Energy Frontier directly explores the fundamental constituents and architecture of the universe. Here accelerators produce the highest-energy particles ever made by man; collisions of these particle beams produce unusual and new particles. |

Experiments at the Intensity FrontierThe Intensity Frontier, accessed with a combination of intense particle beams and highly sensitive detectors, offers a second, unique investigation of fundamental interactions. |
|
Experiments at the Cosmic FrontierThe Cosmic Frontier reveals the nature of dark matter and dark energy by using particles from space to explore new phenomena. Cosmic rays in the earth’s atmosphere, neutrinos from the sun, and gamma rays from deep space, are some of the known natural sources. |
