The Thomas Jefferson National Accelerator Facility (Jefferson Lab) is funded by the U.S. Department of Energy's Office of Science with strong support from the City of Newport News and the Commonwealth of Virginia. As a user facility for scientists worldwide, its primary mission is to conduct basic research of the atom's nucleus at the quark level.


With industry and university partners, Jefferson Lab also has a derivative mission: applied research for using the Free-Electron Lasers based on technology developed at the lab to conduct physics experiments. Additionally, as a center for both basic and applied research, Jefferson Lab reaches out to help educate the next generation in science and technology.

Jefferson Lab is managed and operated for the DOE by the Jefferson Science Associates, LLC. JSA is a limited liability corporation created by Southeastern Universities Research Association and Computer Sciences Corp. specifically to manage and operate Jefferson Lab.
