摘要: 本文采用有限元软件分析了J-TEXT 的完整铁芯模型、等离子体电流丝模型和简化中心螺线管模型的磁场特征,确定了简化中心螺线管的几何参数与电流,之后把有限长度中心通电螺线管参数加到托卡马克模拟程序 TSC 模型中,模拟 J-TEXT 的欧姆放电过程,获得了欧姆放电电流、电子温度、等离子体密度、等离子体电流,磁轴位置等参数。模拟结果与实验结果数据相符,为具有铁芯结构的托卡马克放电模拟提供了有效手段。

Abstract: In order to simulate the discharge process of J-TEXT tokamak with iron core, the magnetic field characteristics of J-TEXT complete iron core model, J-TEXT plasma current wire model and J-TEXT simplified central solenoid model were analyzed by finite element analysis software, and the geometric parameters and current of the simplified central solenoid were determined. Then, the parameters of the finite length central solenoid were input into the TSC(tokamak simulation code) to simulate the ohmic discharge process of J-TEXT, and the ohmic discharge current, electron temperature, plasma density, plasma current and magnetic axis position were obtained. The simulation results were consistent with the experimental data, and an effective method for the simulation of tokamak with iron core was provided.

Key words:  J-TEXT, Iron core tokamak, TSC, Ohmic discharge
