Parametric excitation of drift waves with the pump near the ion cyclotron frequency in a two-ion-species plasma
Parametric excitation of drift waves in a multi-ion species plasma is observed in a range of pump frequencies, ..omega../sub pi//..cap omega../sub i/ much greater than ..omega../sub o//..cap omega../sub i/ approximately equal to 1.3 to 1.6 and the ion concentration ratio, N(He):N(Ne) = 8:2 to 3:7. The dispersion relation and the excitation mechanism are verified.
