Princeton Plasma Physics Laboratory




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







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.




Contributing to a sustainable future.

We’re studying ways to remove fossil fuels from industrial and manufacturing processes to contribute to a Net-Zero America.




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.
