Tokamak Experimental Science

Mission & Vision

The Tokamak Experimental Science Department is dedicated to advancing the tokamak concept for fusion energy science. Tokamaks are machines that confine plasma with strong magnetic fields in a donut shape that scientists refer to as a torus. We perform experimental research, innovating and improving tokamaks at the Princeton Plasma Physics Laboratory (PPPL) and worldwide to enable a world powered by safe, clean and virtually limitless fusion energy.

Through the network of public and private partnerships listed below, our team is at the forefront of fusion research and development to help bring fusion energy to the electrical grid.
