Thomas Jefferson National Accelerator Facility (TJNAF), commonly called Jefferson Lab or JLab, is a U.S. national laboratory located in Newport News, Virginia. Since June 1, 2006, it has been operated by Jefferson Science Associates, LLC, a joint venture between Southeastern Universities Research Association, Inc., and CSC Applied Technologies, LLC. Until 1996 it was known as the Continuous Electron Beam Accelerator Facility (CEBAF); this name is still commonly used for the main accelerator. Founded in 1984, JLab employs over 675 people, and over 2,000 scientists from around the world have conducted research using the facility. Its stated mission is "to provide forefront scientific facilities, opportunities and leadership essential for discovering the fundamental structure of nuclear matter; to partner in industry to apply its advanced technology; and to serve the nation and its communities through education and public outreach."
