On a strong effect of nonresonant three-wave interactions on the saturation of low-threshold parametric decay instability
E. Z. Gusakov, A. Yu. Popov Ioffe Institute, St. Petersburg, 194021 Russia
Abstract:
It has been shown that the nonresonant three-wave interaction between daughter waves trapped in the plasma, which excites strongly damped induced oscillations, strongly affects the nonlinear evolution of the low-threshold parametric decay instability, leading to its saturation through a cascade of successive low-threshold decays. As a result, the anomalous absorption of a microwave pump wave in the electron cyclotron heating of the plasma in toroidal magnetic confinement devices can be significantly reduced.
