托卡马克等离子体中杂质模的研究
Study of Impurity Mode in Tokamak Plasmas
摘要
Abstract
The instability effect driven by impurity mode is studied using a numerical meth-od of integral dispersion equation in toroidal configuration. Impurity modes excited by various impurity ions are investigated under different parameters conditions.It is found that the greater instability is related to the heavier impurity ion mass and higher charge num-bers,but there is an abnormal fact that heavier impurity ions lead to a bigger destabilizing effect on the mode.In addition,the excitation of impurity mode has to exceed the impurity charge concentration threshold,and the impurity ions with lighter mass and lower charge number produce a smaller threshold. The destabilizing effect of impurity mode is gradually suppressed in the stronger and weaker magnetic shear region.The impurity mode with W+8 ion has the narrowest of the spectra width.关键词
