User Facilities at a Glance

FES User Facilities

The Fusion Energy Sciences program supports the following national scientific user facilities:

DIII-D National Fusion Facility (DIII-D)

at General Atomics

DIII-D, the largest magnetic fusion user facility in the U.S., is a tokamak confinement device with significant engineering flexibility to explore the optimization of the advanced tokamak approach to fusion energy production.

National Spherical Torus Experiment – Upgrade (NSTX-U)

at Princeton Plasma Physics Laboratory

The NSTX-U is a magnetic confinement fusion facility employing a spherical torus confinement configuration to explore the potential stability and confinement advantages of this compact tokamak concept.
