受控热核聚变研究及其在我国HT-7超导托卡马克上的最新进展

Controlled thermonuclear fusion and the latest progress on China′s HT-7 supercinducting tokamak

  • 摘要: 受控热核聚变研究在发展了50年后,在2003年进入了一个新的阶段,国际热核聚变实验堆项目将最后选址开工.科学工作者们希望这个在新世纪初开始的项目能成为彻底解决能源问题的发端.中国科学院等离子体物理研究所最近在受控热核聚变科研上取得了长足进展,朝着稳态高温等离子体的方向又跨出了坚实的一步.其HT-7超导托卡马克高温等离子体的持续时间达到63.95s,成为目前世界上能开展分钟级高温等离子体放电的仅有的两个超导托卡马克装置之一.文章主要介绍了中国科学院等离子体物理研究所最新的聚变实验研究进展.

     

    Abstract: After 50 years of research on controlled thermonuclear fusion, a new stage will be reached in 2003, when a site for the International Thermonuclear Experimental Reactor project will be chosen to start the construction. Scientists hope that this project could herald a new era in which the energy problem will be solved completely. The great progress made on the HT-7 superconducting tokamak in China has provided positive and powerful support for fusion research. The HT-7 is one of the only two superconducting tokamaks in the world that can carry out minute-scale high temperature plasma research, and has achieved a duration of 63.95s for the hot plasma discharge. This is a major step towards real steady-state operation of the tokamak configuration. We present an overview of the latest progress on the tokamak experiments in the Institute of Plasma Physics, Chinese Academy of Sciences.
