Exploring the Nature of Matter

Scientists from across the country and around the world come to Jefferson Lab to advance mankind's understanding of the atom's nucleus. To probe nuclei, scientists use continuous beams of high-energy electrons from the lab's Continuous Electron Beam Accelerator Facility, or CEBAF, as well as technologically advanced targets, unique particle-detection systems and ultra-high-speed data acquisition equipment in CEBAF's four experimental halls.

Nuclear and particle physicists from around the world come to Jefferson Lab to perform world-class research in the lab’s four experimental halls. Learn about the research they conduct here and how they are making discoveries about the very heart of matter.

The experiments performed at Jefferson Lab are supported by instrumentation, electronics and software at the cutting edge of technology. Learn about the exotic targets and complex detectors used in JLab’s experiments, as well as the computers and software used to analyze the results.

Learn how experiments are proposed, approved and scheduled.
