12 月 31 日消息，据新华社报道，2021 年 12 月 30 日晚，中科院合肥物质科学研究院等离子体物理研究所有“人造太阳”之称的全超导托卡马克核聚变实验装置（EAST）实现 1056 秒的长脉冲高参数等离子体运行，这是目前世界上托卡马克装置高温等离子体运行的最长时间。News on December 31, according to Xinhua News Agency, on the evening of December 30, 2021, the Hefei Institute of Material Science, Chinese Academy of Sciences, plasma physics research all “artificial suns” called the fully superconducting Tokamak nuclear fusion experimental device (EAST) Realize 1056 seconds of long pulse high-parameter plasma operation, which is the longest time for high-temperature plasma operation of a tokamak device in the world.
The operating time of China’s artificial sun exceeds one thousand seconds. EAST has a nuclear fusion reaction mechanism similar to the sun and is used to explore the application of nuclear fusion energy. EAST is about 11 meters high, about 8 meters in diameter, and weighs more than 400 tons. It looks like a huge “tank”. Over the past 10 years since it was built, it has achieved stable 101.2 second steady-state long pulse high confinement plasma operation and electron temperature. Major international breakthroughs such as plasma operation at 100 million degrees Celsius for 20 seconds.
IT Home has learned that the engineering design of the next-generation “artificial sun”-the China Fusion Engineering Experimental Reactor has been completed, and the comprehensive research facility for the key system of the fusion reactor is under construction.
EAST 拥有类似太阳的核聚变反应机制，用来探索核聚变能源应用。EAST 高约 11 米，直径约 8 米，重 400 余吨，看上去像一个巨大的“罐子”，建成 10 余年来，先后实现了稳定的 101.2 秒稳态长脉冲高约束等离子体运行、电子温度 1 亿摄氏度 20 秒等离子体运行等国际重大突破。
