Department of Energy-Funded Nuclear Fusion Breakthrough Achieves “Paradigm Shift” in Magnetic Confinement


Scientists have achieved a breakthrough in magnetic confinement that could potentially quicken the advancement for fusion energy.

At the heart of the new design is a theoretical approach that offers a promising solution to one of fusion energy’s most demanding problems: how to prevent energy-draining particles from escaping reactor chambers. Most promising of all, the new method can achieve this while still preserving the accuracy required for operating these high-energy reactors, a factor that has long hindered progress in magnetic confinement approaches in the past. A key focus for the team’s research involves stellarators, which are fusion reactors that feature a toroidal (donut-shaped) design that rely on elaborate external windings that control the magnetic fields produced within.
