Magnetic Fusion

General Atomics (GA) has been an international leader in magnetic fusion research since the 1960s. The DIII-D National Fusion Facility, operated by GA for the U.S. Department of Energy (DOE), is the largest magnetic fusion research facility operating in the U.S. Magnetic fusion research at GA has led to vital scientific discoveries as well as spinoff technologies that have advanced the state of the art in medical diagnostics, transportation, semiconductors, electronics, and defense applications, including the Electromagnetic Aircraft Launch System (EMALS) being deployed on the next generation of U.S. Navy aircraft carriers.

GA is a key partner in ITER — one of the largest scientific programs in history — which seeks to demonstrate the scientific and technological feasibility of fusion power, a potentially limitless source of clean energy. The ITER facility is currently being constructed in France by a consortium of 35 nations. GA is manufacturing major components for this worldwide initiative, including diagnostics systems and the Central Solenoid, the world's largest pulsed superconducting electromagnet.

GA's Theory and Computational Science program advances the fundamental theoretical understanding of fusion plasmas through development and application of industry-leading computer simulations. The theory program works with DIII-D to validate models and simulations against robust experimental data.


The DIII-D National Fusion Facility program, operated by GA for the Department of Energy, is a cornerstone of the U.S. national fusion program strategy.


GA is fabricating the Central Solenoid for the international ITER project, an unprecedented scientific partnership that aims to demonstrate the feasibility of fusion power as a clean-energy resource on a global scale.
