【摘要】 本文介绍了中国环流器二号A(HL-2A)装置概况、系统工程以及在磁约束聚变物理研究方面取得的若干重要进展,尤其是在HL-2A装置上成功实现了具有边缘局域模的高约束模式运行,是我国磁约束聚变实验研究史上具有里程碑意义的重大进展.近年来利用该装置可近性好,原创的加料与控制技术以及先进的高时空分辨诊断系统等独特优势,在HL-2A装置上开展了国际热核聚变实验堆(International Thermonuclear Experimental Reactor,ITER)及未来聚变堆等离子体相关的前沿物理问题与关键技术的研究,获得了一批国际磁约束核聚变领域创新科技成果,为ITER的运行与实验以及未来聚变堆的设计提供了重要技术基础与支撑.更多还原

【Abstract】 This paper presents the status of the HL-2A tokamak and its auxiliary systems, and the highlights of the experiments on magnetic fusion plasma in HL-2A. In particular, China’s first high confinement mode(H-mode) operation has been achieved on this device which is an important milestone in the history of magnetic fusion research in China. Due to its good accessibility, innovative fueling technologies and many advanced diagnostics with high spatiotemporal resolution,an amount of key issues on magnetic fusion plasma have been investigated and a series of innovative achievements have been obtained. They will provide important scientific and technical basis for ITER operation and design of future fusion DEMO.更多还原
