The Thomas Jefferson National Accelerator Facility, commonly known as Jefferson Lab or JLab, is a U.S. national laboratory located in Newport News, Virginia. Funded by the Department of Energy, it operates under the auspices of the Office of Science and is primarily focused on nuclear physics research. The facility’s centerpiece is the Continuous Electron Beam Accelerator Facility (CEBAF), which utilizes a superconducting radiofrequency accelerator to produce a continuous beam of high-energy electrons. These electrons are used to probe the nuclei of atoms, helping scientists better understand the fundamental structure of matter. Jefferson Lab also hosts a Free-Electron Laser program and supports a broad range of scientific programs which extend beyond nuclear physics to include materials science and medical imaging technologies. Additionally, it plays a significant role in advancing accelerator science and technology, which has applications in various fields such as medicine and industry.
