摘　　要：[目的]磁约束核聚变是解决能源问题的有效途径之一。为了实现准稳态运行,超导磁体(特别是高场高温超导磁体)已成为未来托卡马克设计的首选方案。[方法]介绍了EAST的最新实验进展及未来研究计划,并从超导磁体技术方面总结了未来聚变装置CFETR的最新进展。[结果]2021年底,世界首个全超导托卡马克EAST(Experimental Advanced Superconducting Tokamak)成功实现1 056 s长脉冲高参数等离子体运行,创造最长运行时间的世界记录。[结论]中国聚变工程试验堆(CFETR, China Fusion Engineering Test Reactor)的设计已经完成,它将填补国际热核聚变实验堆(ITER, International Thermonuclear Experimental Reactor)和示范堆(DEMO)间的空白。[Introduction]Magnetically confined fusion is an effective way to solve the energy problem. To direct to quasi-steady state discharges and their relevant physics, the superconducting magnet(especially the high field HTS magnet) had become the first choice for tokamak design in the future. [Method]This reserch was devoted to introduce the recent experimental progress and future research schemes of EAST, and summarized the latest progress of CFETR, especially the research on superconducting magnet. [Result]EAST device, the world’s first full superconducting tokamak, has achieved a new pulse length world record(1 056 seconds) for high temperature tokamak plasma by the end of 2021. [Conclusion]The designs of CFETR, which aim to bridge the gaps between the fusion experiment ITER and the demonstration reactor(DEMO), have been carried out within CFETR National design team.
