The Princeton Plasma Physics Laboratory (PPPL) at Princeton University is a leading research facility dedicated to plasma physics and fusion energy. Founded in 1951, PPPL was spearheaded by astrophysicist Lyman Spitzer’s vision of harnessing
fusion—the process that powers stars—to create a clean and virtually limitless energy source. PPPL’s cutting-edge research includes projects like the National Spherical Torus Experiment-Upgrade (NSTX-U), Magnetic Reconnection Experiment (MRX), and collaborations on the international ITER project. The lab also focuses on plasma-material interactions essential for developing durable fusion reactors. Beyond research, PPPL engages in extensive educational outreach, offering programs for students, educators, and the public, while training the next generation of scientists. Through its innovative work and global partnerships, PPPL is paving the way towards a sustainable energy future.
