China Moves Closer to Build ‘Artificial Sun’ After Testing 582-Ton Fusion Magnet
Researchers said the 582-tonne magnet and central solenoid were built with domestic technology, advancing China’s plan for commercial fusion power.
- China's Institute of Plasma Physics completed acceptance testing on Tuesday of the world's largest toroidal superconducting fusion magnet, a 582-tonne device designed to confine plasma at temperatures exceeding 100 million degrees Celsius.
- Researchers developed the magnet using entirely domestic materials during a 6-year program that generated 47 patents and 25 industry standards, marking China's technological independence in fusion component manufacturing.
- Scientists also tested the reactor's 'heart,' a high-temperature superconducting central solenoid coil, which researchers describe as the 'main spark plug for the fusion process' that ignites and sustains plasma.
- China's three-stage fusion roadmap targets assembly of the Burning Plasma Experimental Superconducting Tokamak by 2027, with first fusion-based electricity generation from the China Fusion Engineering Demonstration Reactor expected around 2030.
- While maintaining participation in the International Thermonuclear Experimental Reactor project, China is simultaneously advancing independent commercial fusion development, positioning the nation as a leader in global fusion research.

China built an artificial sun using a 582-ton magnet
China just built a magnet so enormous that calling it “heavy” feels like underselling the situation. The superconducting magnet weighs 582 metric tons, stretches 21 meters long, and is designed to help create a controlled nuclear fusion reaction with plasma heated to around 100 million degrees Celsius. For context, that’s roughly six times hotter than the core of the actual Sun. Welcome to the wonderfully unhinged world of fusion energy. The ‘Ar…
China has built a 582-ton giant magnet to help its 'Artificial Sun' confine plasma hotter than 100 million°C - The Times of India
China has achieved a major milestone in its pursuit of commercial nuclear fusion by completing the construction and testing of a colossal 582-ton supe.
China has successfully tested the largest superconductor magnet built for a fusion reactor. The piece will be essential to contain the plasma and bring the country closer to its goal of generating electricity through the same process that feeds the Sun
Palladium and titanium kept fusion measurable at low energy levels – the yield was up to a trillion times higher than the theoretical value.
