NONLINEAR MECHANICS OF UNIVERSAL PLASMA INSTABILITIES.
Abstract
Certain nonlinear mode-competition phenomena observed in experiments on the universal plasma instability in a thermal plasma device (Q-machine) have been analyzed by extending the usual phase-plane methods of nonlinear mechanics, the phase-plane coordinates in this case being the mode energies. Ion Landau damping of the universal instability provides an experimental means for selective control of the mode amplitudes. The results of mode-competition experiments using this technique are in agreement with the theoretical analysis and the relevance of the results to similar phenomena in gas lasers and lumpedparameter vacuum-tube circuits is discussed.
