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.
The DIII-D National Fusion Facility (DIII-D), at General Atomics, is the largest magnetic fusion research experiment in the U.S., with a program mission to establish the scientific basis for the optimization of the tokamak approach to fusion energy production. Capabilities of this facility include a flexible field-shaping coil system to produce a variety of plasma shapes, a diverse mix of auxiliary heating and current drive systems, coil sets both inside and outside the vacuum vessel that are used to correct error fields and study the plasma response to perturbing magnetic fields, all-carbon plasma-facing surfaces, over 50 diagnostic systems to examine plasma parameters, and an advanced digital control system for feedback control of the plasma.
Research at this facility contributes to world-leading science by 1) providing solutions to physics and operational issues critical to the success of ITER; 2) developing the physics basis for steady-state tokamak operation required for efficient power production; 3) contributing substantially to the technical basis for a Fusion Nuclear Science Facility (FNSF); and 4) advancing the fundamental understanding and predictive capability of fusion science.
