实验先进超导托卡马克装置（EAST）是世界上第一台全超导托卡马克装置，由我国自行设计和建造。作为一台中型超导托卡马克，EAST成功地弥补了短脉冲中型托卡马克和长脉冲大型托卡马克之间的差距。EAST配备了国际先进的热核实验堆（ITER）技术，可实现1000 s长的脉冲放电。在未来10年内，EAST将成为世界上为数不多的用作实验平台的托卡马克之一，可用于研究高性能长脉冲放电条件下的等离子体物理和工程技术。在过去的几年里，EAST在偏滤器结构的“低约束模式”等离子体中获得了400 s长的脉冲，在“高约束模式”等离子体中获得了30 s长的可重复脉冲，创造了新的世界纪录。EAST将用于解决与ITER和未来聚变反应堆的高性能稳态运行有关的关键物理和工程问题。EAST的研究将为我国未来聚变堆的设计和运行提供重要依据，为稳态、高效、安全的托卡马克聚变堆提供技术和物理基础。
Experimental advanced superconducting tokamak (EAST) is the first fully superconducting tokamak 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.
