Long-wavelength ion-sound parametric instability of plasma in magnetic field
We have studied numerically the dependence of the frequency and growth rate of the ion sound wave on the wave vector in plasma in the electric field of a helicon for long-wavelength oscillations when the wavelength of ion sound wave is equal to the order of magnitude to or exceeds the electron Larmo...
