“Artificial Sun” achieves fusion milestone: 1,066-second plasma
China’s quest to harness the power of the stars reached a historic milestone as the Experimental Advanced Superconducting Tokamak (EAST), often called the “artificial Sun,” achieved a record-breaking high-confinement plasma operation lasting 1,066 seconds. This feat, accomplished by the Institute of Plasma Physics under the Chinese Academy of Sciences (ASIPP), far surpasses the previous record of 403 seconds set by EAST in 2023. This breakthrough marks a major step in fusion energy research, showcasing advancements in sustaining high-temperature plasma for prolonged periods. The ability to maintain stable operation for over 1,000 seconds is crucial for developing future fusion reactors capable of generating continuous and clean energy. What makes EAST unique? EAST, the world’s first fully superconducting tokamak, boasts several innovative features. Its non-circular cross-section, fully superconducting magnets, and actively water-cooled plasma-facing components enable advanced steady-state plasma operation modes. While it is smaller than the International Thermonuclear Experimental Reactor (ITER), EAST is comparable in shape and design, offering greater flexibility for experimental configurations. Since its launch in 2006, EAST has served as an open test platform …
