Abstract

Experimental Advanced Superconducting Tokamak (EAST) was built to demonstrate high-power, long-pulse operations under fusion-relevant conditions, with major radius R = 1.9 m, minor radius a = 0.5 m, and design pulse length up to 1000s. It has an ITER-like D-shaped cross-section with two symmetric divertors at the top and bottom, accommodating both single null and double null divertor configurations. EAST construction was started in 2000, and its first plasma was successfully obtained in 2006. In the past 15 years, plasma-facing components, plasma heating, diagnostics, and other systems have been upgraded step by step to meet its mission on exploring of the scientific and technological bases for fusion reactors and studying the physics and engineering technology issues with long pulse steady-state operation. An advanced steady-state plasma operation scenario has been developed, and plasma parameters were greatly improved. Meanwhile, front physics on the magnetic confinement plasmas have been systemically investigated and lots of fruitful results were realized, covering transport and confinement, MHD stabilities, pedestal physics, divertor and scrap-off layer (SOL) physics, and energetic particle physics. This brief review of EAST on engineering upgrading, stand-steady operation scenario development, and plasma physics investigation would be useful for the reference on construction and operation of a superconducting tokamak, such as ITER and future fusion reactor.

所有超导托卡马克： EAST

先进超导托卡马克实验装置（EAST）是为了在核聚变相关条件下演示大功率、长脉冲运行而建造的，其主要半径 R = 1.9 米，次要半径 a = 0.5 米，设计脉冲长度可达 1000 秒。它具有类似于热核聚变实验堆的 D 型横截面，顶部和底部有两个对称的分流器，可用于单空和双空分流器配置。EAST 于 2000 年开始建造，2006 年成功获得首个等离子体。在过去的15年中，面向等离子体的组件、等离子体加热、诊断和其他系统逐步升级，以满足其探索聚变反应堆的科学和技术基础以及研究长脉冲稳态运行的物理和工程技术问题的任务。开发了先进的稳态等离子体运行方案，等离子体参数得到极大改善。同时，对磁约束等离子体的前沿物理进行了系统研究，取得了大量丰硕成果，涵盖了输运与约束、MHD稳定性、基座物理、分流层和刮除层（SOL）物理以及高能粒子物理等方面。本文简要回顾了EAST在工程升级、稳态运行方案开发和等离子体物理研究方面的工作，对建造和运行超导托卡马克（如ITER和未来的聚变反应堆）具有参考价值。
