Magnetic Fields Breakthrough Boosts Fusion Plasma Confinement

Researchers at Laboratorio Nacional de Fusión–CIEMAT have developed a new family of magnetic fields that enhance plasma confinement in fusion reactors, potentially simplifying reactor design and advancing the realization of fusion energy. These omnigenous magnetic fields allow for better particle confinement without complex equipment, broadening the possibilities for future stellarator reactors. The study, published in Physical Review Letters, suggests that optimizing magnetic fields in a 'piecewise omnigenous' manner could improve the efficiency of fusion devices.
