Scientists Build Breakthrough Nuclear Fusion Device With Household Magnets One of the most promising designs for a nuclear fusion reactor is the tokamak, a chamber that uses powerful magnets to create a magnetic field to confine the hot plasma produced by nuclear fusion in the shape of a torus, or doughnut. A detailed study confirms that record setting magnets built by the plasma science and fusion center and commonwealth fusion systems meet the requirements for an economical, compact power.
Promising Nuclear Fusion Experiment Adds Magnets Popular Science In september 2021, researchers at the psfc developed a new type of magnet that could function at 20 kelvin ( 253 degrees celsius). nicknamed rebco for its constituent material, rare earth barium. Over the next four years, hartwig led a research project at mit with cfs that further developed the magnet technology and scaled it to create a 20 tesla superconducting magnet—a suitable size for a nuclear fusion power plant. A fusion reactor, or tokamak, aims to capture the energy released when nuclei of deuterium and tritium, the heavy isotopes of hydrogen, fuse to produce helium and energetic neutrons. to do that, a tokamak relies on intense magnetic fields to trap and squeeze a superhot ionized gas, or plasma, within a doughnut shaped vacuum chamber. Mit researchers confirm that radiation does not impact rebco superconducting magnets, removing a critical concern and accelerating progress toward practical fusion energy.

As takeyama noted in the press release, that means his team's device can generate close to the minimum magnetic field strength and duration needed for stable nuclear fusion — and it puts us all one step closer to the unlimited clean energy we've been dreaming about for nearly a century. A nuclear fusion experiment at the university of wisconsin madison has set a record for the strongest steady magnetic field confining a plasma, ushering in new hope that forthcoming. For the first time, scientists have built a fusion experiment using permanent magnets, a technique that could show a simple way to build future devices for less cost and allow researchers to test new concepts for future fusion power plants.
