DIII-D

DIII-D

The DIII-D Research Program's mission is to optimize the tokamak approach to fusion energy production. Located in San Diego and in operation since 1986, the DIII-D National Fusion facility is the largest magnetic fusion research experiment in the United States.

Operated by General Atomics for the U.S. Department of Energy, DIII-D is an international program with 90 participating institutions; the Center for Energy Research is the largest University collaborator on this project. Our research focuses on understanding the flow of heat, particles, and momentum across the confining magnetic field to the tokamak wall.
