On high-frequency heating of a dense plasma in a magnetic field

High-frequency heating of plasma in a magnetic field has been studied. The heating is caused by excitation of potential plasma oscillations. The main nonlinear process is induced scattering on ions. The oscillation distribution in a K space turns out to be sharply anisotropic, the oscillations being concentrated near the surface of the K=K0 sphere. The energy flow into the plasma has been calculated. The portion of energy absorbed by ions has been shown to be comparable with the energy flow into the electrons. The question of the angular structure of turbulence parametric spectra has been investigated
