Electromagnets are a key part of the fusion machines being developed by Helion Energy in Washington. Not only do they shape, accelerate and compress the plasma, they also help recover energy as the plasma pushes […]
DEVENS, Mass. and TOKYO (Sept. 30, 2026) — Commonwealth Fusion Systems, a leading developer of fusion energy, today announced a landmark supply agreement for high-temperature superconducting tape with Fujikura Ltd. as it accelerates the commercial […]
Ridgway Machines has appointed Mike Allen as its new managing director to lead a new phase of growth for the Tokamak Energy subsidiary. Founded in 1920, the Leicester, UK-based engineering company is a designer and […]
One of the world’s largest superconducting toroidal field coils, manufactured by the National Institutes for Quantum Science & Technology and Toshiba Corporation, has successfully passed excitation testing under cryogenic conditions at -269°C. The test replicates […]
Making a custom magnetic assembly often calls for an orchestration of intricate design engineering and skillful fabrication. Perhaps that is truer nowhere than at ITER in France where engineers and technicians are wrestling with the demands of building a massive magnetic tokomak for the purpose of generating fusion energy. They are developing welding procedures for crafting first-of-a-kind components and devising strategies for welding in the confined spaces of a revolutionary creation, helping to define the techniques and standards that may shape fusion projects for decades to come. […]
For nearly a century, magnet technology at Berkeley Lab has shaped global research, enabling massive machines and major discoveries – and there’s more yet to come. […]
Big magnets and big money are at the core of a high stakes race to commercialize fusion energy, aiming ultimately to transform the world’s energy supply with the immense power of zero-carbon fusion. This article highlights the progress of two pioneering companies located only a two-hour drive apart — General Fusion in Richmond, British Columbia, Canada and Helion in Everett, Washington in the U.S. The technologies of both companies rely on powerful electromagnets, eschewing the use of more expensive and complex superconducting magnets typically used in tokamaks.
