摘要：
The effect of an impurity ion species on the stability of the toroidal ηi mode is investigated using the kinetic ion response. Impurities have a stabilizing effect on this mode in the flat density limit because of increased dilution. However, for moderately peaked density profiles, the ηi mode can be destabilized because of resonance with the magnetic drift frequency of impurities. © 1990 IOP Publishing Ltd.
