A significant stride in fusion energy research has been made with the delivery of a colossal 440-ton toroidal field coil box, a crucial component for the world’s largest fusion magnet system. This ...

After two decades of design, production, fabrication and assembly on three continents, the historic, multinational ITER fusion energy project today celebrates the completion and delivery of its ...

The bundle of magnets at the heart of the U.S. Department of Energy's Princeton Plasma Physics Laboratory's (PPPL) National Spherical Torus Experiment-Upgrade (NSTX-U) is the star of the show. Its ...

As noted in the paper by [P. Helander] et al., the use of permanent magnets can substantially simplify the magnetic-field coils of a stellarator, which are then primarily used for the toroidal ...

Japan's Toshiba Energy Systems & Solutions Corporation announced today it has completed the manufacture of the first of four toroidal field coils it is supplying to the International Thermonuclear ...

A tokamak, however, is the real deal – a scientific device that produces energy from fusion. And a large-scale version is currently being built in southern France as part of the ITER initiative. A ...

Imagine two toroidal permanent magnets arranged such that one is floating above the other for year after year. Where is the energy that powers this effect coming from? A couple of months ago, I penned ...

The largest superconducting magnet ever built has successfully been powered up to its operating conditions at the first attempt. Called the Barrel Toroid because of its shape, this magnet is a vital ...

Magnet technology has advanced, year-over-year, pulled by the desire of scientists for ever-higher magnetic fields. But progress has been paced by new developments in properties of materials needed to ...

A researcher in New Jersey says he had a nuclear fusion breakthrough while helping his son with a science project. He realized he could explore which kinds of permanent magnets could be powerful and ...
