ANOMALOUS HEATING BY ION SOUND TURBULENCE

The kinetic equation for electrons including Coulomb collisions and scattering by ion sound and related spectra is reduced to a system of equations for the energy distribution and the anisotropic part. The energy distribution is obtained for the cases where Coulomb collisions, runaway or turbulent heating dominates. Resistivity, heating rate, and the dispersion relation are significantly modified for the self-consistent non-Maxwellian distribution. Applications to turbulent heating by ion sound are made. © 1978 American Institute of Physics.
