Powering possibilities. : What is Plasma? We’re tackling the world’s toughest science and technology challenges using plasma, the fourth state of matter. What is Plasma? Pause video ■ Developing clean energy for all. We’re leaders in the science and engineering behind the development of fusion — a clean, safe, and virtually limitless source of energy. Top Projects NSTX-U ITER LTX-beta Building innovative technologies. We’re improving the production of microchips like those used in laptops and smartphones, as well as aiding in the production of key elements used in quantum computers. MICROELECTRONICS QUANTUM MATERIALS AND DEVICES Contributing to a sustainable future. We’re studying ways to remove fossil fuels from industrial and manufacturing processes to contribute to a Net-Zero world. ELECTROMANUFACTURING Aerosol Science for the Climate Exploring the universe and beyond. We strive to understand plasma from the lab to the cosmos, and for good reason: plasma, the fuel of fusion, makes up 99% of the visible universe.

Learn More Our Story So Far Where we've been... Our roots go back to 1951 when magnetic fusion research at Princeton began under the code name “Project Matterhorn.” Lyman Spitzer, Jr., professor of astronomy at Princeton University, conceived of a plasma being confined in a figure-eight-shaped tube by an externally generated magnetic field. He called this concept the "stellarator," and took this design before the Atomic Energy Commission in Washington. Shortly thereafter, this Laboratory was born. Our History ...and where we're going. Princeton Plasma Innovation Center (PPIC): This multimillion-dollar building will serve as an international hub of fusion research and a platform for new programs. Its modern and efficient design will support the Lab’s expanded scientific mission in microelectronics, quantum materials and devices, and sustainability science. With generous funding from the Department of Energy, PPIC will be the first new structure on the Laboratory campus in 50 years. Read More about ...and where we're going.
