Parametric decay instability of plasma with ions of two grades in a field of a powerful wave of pumping

Annotations languages:

Decay of a powerful wave of pumping on two electrostatic ionic cyclotron waves in a case when relative velocities of particles of plasma in a field of a wave of pumping are comparable to their thermal velocities is investigated. On the basis of a method, the offered author earlier, determines gears of excitation of instability depending on a wavelength of originating oscillations. The estimation of an increment of instability is made. The possible level of saturation of instability owing to nonlinear frequency shift is established.
