China achieves major breakthrough in fusion energy with record-breaking superconducting magnets

China announced Saturday a major advance in fusion energy development after successfully completing and testing two critical superconducting magnet systems for a next-generation reactor, the Institute of Plasma Physics under the Chinese Academy of Sciences said. The institute said both the Toroidal Field superconducting magnet and a high-temperature superconducting central solenoid coil passed rigorous development approval procedures and full-parameter performance tests. Researchers emphasized the systems were developed with entirely domestic technology and manufacturing, achieving 100 percent localization of core components. The Toroidal Field magnet has officially become the largest magnet ever constructed for a fusion device, measuring 21 meters in length, 12 meters in width and 3.3 meters in height while weighing 582 tonnes. Scientists noted the magnet possesses a volume approximately 1.3 times larger than the toroidal field magnets used in the international ITER fusion project and stores three times more magnetic energy. Development required six years of intensive work, resulting in 47
