HT－7托卡马克中等离子体平衡研究

ANALYSIS OF PLASMA EQUILIBRIUM IN THE HT-7 TOKAMAK

本文解决了二维轴对称近似下带铁芯的托卡马克中等离子体平衡问题，计算了ＨＴ－７托卡马克中的等离子体平衡位形以及极向场系统的非线性电感和垂直场系数。最后应用Ｋｉｒｃｈｈｏｆｆ方程组和平衡垂直场公式得到了一组等离子体、加热场和垂直场线圈的电流波形的自洽曲线。

A calculation for the plasma equilibrium in tokamak with iron core transformer is performed in an axisymmetric,two-dimensional model. Also calculated are the equilibrium configurations ,the nonlinear inductances and the vertical field efficiencies of the poloidal system in HT-7. Kirchhoff's equations and equilibrium formulas are used to derive the time evolution of the currents in the plasma,the primary of transformer and the control windings.
