Parametric instabilities during electron cyclotron resonance heating in plasmas
Abstract
The parametric decay instability of an extraordinary electromagnetic wave into a highfrequency magnetized electron plasma wave and a lowfrequency wave (mixedmode kinetic Alfve'n wave or magnetosonic wave) propagating at an angle with respect to the static magnetic field has been considered. For the typical set of parameters of the tokamak when the kinetic Alfve'n wave is a lowfrequency wave, the convective threshold is ~10 kW/cm^{2}. .AE
