Nonlinear effect in a plasma

R. Tavzes ; University of Ljubljana and Institute “J. Stefan”, Ljubljana

Abstract

Experimental results have been obtained which show that a collisional drift instability in a bounded plasma column behaves like a classical Van der Pol oscillator. The plasma is produced by microwave heating at ECR and plasma density is varied periodically by amplitude modulation of the bf power at a modulation frequency dose to the instability frequency. The experimental results are in good agreement with a behaviour of a Van der Pol oscillator for drive frequencies near the center frequency of the oscillator.
