China has achieved a major breakthrough in fully superconducting tokamak magnet technology, successfully maintaining steady-state high-confinement plasma operation for over 1,000 seconds, setting a new world record. This accomplishment was made by the EAST team at the Institute of Plasma Physics under the Chinese Academy of Sciences, marking a critical step forward in controllable nuclear fusion energy research. The fully superconducting magnet, core component of the tokamak device, generates powerful magnetic fields to confine plasma at temperatures exceeding 100 million degrees Celsius. This breakthrough resolves key scientific challenges in long-pulse high-parameter plasma operation, providing crucial technical support for future fusion reactor construction. The technology is expected to accelerate the clean energy revolution and lay a solid foundation for realizing the dream of ‘artificial sun’.
