Abstract
The effects of unstable modes, connected with the presence of impurity ions in a magnetically confined high-temperature plasma column and not dependent on wave-particle resonances that involve only a small portion of velocity space, are discussed for two significant regimes: a collisional one corresponding to relatively short mean free paths of the main ion population and a collisionless one in which a significant fraction of this population is magnetically trapped.Keywords
