Abstract

Abstract: Simulation of plasma boundary reconstruction in the SUNIST spherical tokamak using current filament (CF) model has been demonstrated. The calculation results show that plasma free-boundary can be identified by filament current method quickly. The average boundary error in radius is less than 6mm between CF model and EFIT code.

Key words: Spherical tokamak, Boundary reconstruction, Filament current method

摘要： 利用电流丝模型对SUNIST球形托卡马克等离子体边界重构进行了模拟计算。结果表明，用电流丝模型能够比较好地对等离子体自由边界进行快速识别，与EFIT平衡计算的边界径向平均误差小于6mm。
