Princeton Plasma Physics Laboratory

Princeton Plasma Physics Laboratory (PPPL) is a United States Department of Energy national laboratory for plasma physics and nuclear fusion science located on Princeton University's Forrestal Campus in Plainsboro Township, New Jersey. Its primary mission is research into and development of fusion as an energy source. It grew out of the top secret Cold War project to control thermonuclear reactions, called Project Matterhorn. In 1961, after declassification, Project Matterhorn was renamed the Princeton Plasma Physics Laboratory.
