The Thomas Jefferson National Accelerator Facility, located in Newport News, Virginia, is operated by Jefferson Science Associates, LLC for the Department of Energy’s Office of Science. The primary mission of the lab is to explore the fundamental nature of confined states of quarks and gluons, including the nucleons that comprise the mass of the visible universe. Jefferson Lab is also a world-leader in the development of the superconducting radio-frequency (SRF) technology utilized for the lab's Continuous Electron Beam Accelerator Facility (CEBAF). This technology is the basis for an increasing array of applications at Jefferson Lab, other DOE labs, and in the international scientific community. Jefferson Lab has more than 700 full-time employees and an international scientific user community of more than 1,300 researchers whose work has resulted in scientific data from 175 experiments to date. Research at Jefferson Lab also contributes to thesis research material for about one-third of all U.S. Ph.D.s awarded annually in Nuclear Physics. The Lab's outstanding science education programs for K-12 students, undergraduates and teachers build critical knowledge and skills in the physical sciences that are needed to solve many of the nation's future challenges.
