摘要

等离子体平衡重构在等离子体实验的分析和模拟中发挥着重要作用。EAST 托卡马克已经采用了具有压力和边缘电流约束的动力学平衡重建。然而，内部安全系数（q）曲线并不准确。本文提出了一种将 q 曲线约束纳入动力学平衡重构的新方法。q剖面由偏振干涉仪（POINT）重建得出。将包含q剖面约束信息的虚拟探测器添加到动力学平衡重建程序的输入中，以获得最终平衡。新的平衡产生了更精确的内部 q 曲线。这种改进的方法将有助于分析 EAST 实验。

Kinetic equilibrium reconstruction with internal safety factor profile constraints on EAST tokamak

Reconstruction of plasma equilibrium plays an important role in the analysis and simulation of plasma experiments. The kinetic equilibrium reconstruction with pressure and edge current constraints has been employed on EAST tokamak. However, the internal safety factor (q) profile is not accurate. This paper proposes a new way of incorporating q profile constraints into kinetic equilibrium reconstruction. The q profile is yielded from the Polarimeter Interferometer (POINT) reconstruction. Virtual probes containing information on q profile constraints are added to inputs of the kinetic equilibrium reconstruction program to obtain the final equilibrium. The new equilibrium produces a more accurate internal q profile. This improved method would help analyze EAST experiments.
