EAST超导托卡马克

Experimental advanced superconducting tokamak

EAST超导托卡马克是我国设计建造的国际上第一个建成的全超导托卡马克实验装置.EAST的建成填补了从短脉冲中型常规托卡马克向长脉冲大型超导托卡马克过渡过程中"中型超导托卡马克"的空缺.EAST具有国际热核聚变实验堆(ITER)类似先进技术,具有与ITER类似的超过1000 s的长脉冲高参数运行能力,是未来10年国际上极少数有能力在高参数条件下开展长脉冲聚变等离子体物理和工程技术研究的实验平台.EAST已经取得了超过400 s的偏滤器位形等离子体以及稳定重复的超过30 s的长脉冲"高约束模"等离子体,创造了新纪录.EAST致力于解决ITER及未来聚变堆高性能稳态运行相关的关键物理和工程问题.这些研究将为中国未来聚变实验堆的设计和运行提供重要的依据,并为未来建造稳态、高效、安全的托卡马克类型的聚变反应堆提供重要的工程技术和物理基础.

Experimental advanced superconducting tokamak （EAST） is the first fully superconducting tokarnak device in the world, designed and built in our own country. As a ＇medium-size superconducting tokamak＇, EAST has successfully bridged the gap between the short-pulse medium-size tokamak and the long-pulse large-size tokamak. EAST is equipped with the advanced international thermonuclear experimental reactor （ITER） based technology, and can realize 1000-s-long pulse discharges. In the next 10 years, EAST will be one of the few tokamaks in the world used as an experimental platform, which could be used for studying plasma physics and engineering technology under conditions of high-performance long-pulse discharges. During the past few years, EAST has achieved 400-s-long pulses in ＇low confinement mode＇ plasma of divertor configuration, and repeatable 30-s-long pulses in ＇high confinement mode＇, setting a new world record. EAST will be used for solving key physical and engineering issues related to the high-performance steady state operation at the ITER and future fusion reactors. The studies on EAST will provide an important basis for the design and operation of future Chinese fusion reactors, and will provide the technological and physical basis for a steady-state, high-efficiency and safe tokamak fusion reactor.
