利用外部磁场测量和二维Hall - MHD数值模拟，提出了一种新的模型来重建TS - 6球形托卡马克在合并启动过程中的内部磁结构。测量域外的一些零尺寸数值线圈负责产生与位于测量边界上的外部探头测量的相同的极向磁通值。研究表明，在合并过程中，重构结果与实测值有6%的偏差。©2022日本电气工程师学会。Wiley期刊有限责任公司出版。
A novel model to reconstruct the magnetic configuration inside the TS‐6 spherical tokamak during the merging start‐up is presented, utilizing the external magnetic measurements with a 2D Hall‐MHD numerical simulation. A number of zero size numerical coils outside the measurement domain are responsible to produce the same poloidal flux values as the ones measured by the external probes located on the measurement boundary. This study shows that the reconstruction agrees with the measured one by 6% deviation during the merging. © 2022 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.
