Six 270,000-lb modules that can help power fusion at ITER developed

General Atomics (GA), a San Diego-based company, has completed the development of the Central Solenoid Modules, which constitute the largest and most powerful pulsed superconducting magnet ever built. These six modules, each weighing over 270,000 pounds, took more than two years each to fabricate and were produced at GA’s Magnet Technologies Center in Poway, California. Once shipped to the ITER fusion facility under construction in southern France, the modules will be stacked to form a massive system over 18 meters tall, weighing more than 1,000 tons. This milestone marks a significant technical achievement for the U.S. and positions GA at the forefront of global fusion innovation. The Central Solenoid will play a critical role in powering fusion reactions at ITER, an international fusion science project. GA’s successful completion of this 15-year-long project demonstrates the company’s advanced engineering capabilities and the strength of its specialized global supply chain. Beyond ITER, the expertise gained will support future fusion technologies and other applications involving
