摘要

已开发出实时磁控制功能，可为先进的分流器配置提供多个等离子体形状参数的精确控制，包括双空、Super-X、X 点目标和 X 分流器，这在 MAST 升级（MAST-U）球形托卡马克上尚属首次。在2022-2023年MAST-U实验活动中，针对先进的MAST-U分流器配置，成功实现了对不同等离子体形状变量的实时磁平衡控制。介绍了MAST-U边界重建算法LEMUR的应用，并与离线平衡重建和诊断测量进行了比较。还介绍了使用一套控制分析工具（统称为 TokSys）设计和验证轴对称磁控制方案的过程。

Real-time plasma equilibrium reconstruction and shape control for the MAST Upgrade tokamak

Real-time magnetic control has been developed to deliver precise control of multiple plasma shape parameters for advanced divertor configurations, including double-null, Super-X, X-point target and X-divertor for the first time on the MAST Upgrade (MAST-U) spherical tokamak. Successful real-time magnetic equilibrium control of different plasma shape variables has been accomplished in the 2022–2023 MAST-U experimental campaign for the advanced MAST-U divertor configurations. Application of the MAST-U boundary reconstruction algorithm, LEMUR, is described and compared with off-line equilibrium reconstruction and diagnostic measurements. The process of design and verification of the axisymmetric magnetic control schemes using a suite of control analysis tools (known collectively as TokSys) is also described.
