Anomalous heating by ion sound turbulence

Creators

Description

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 and other transport effects will be considered in a companion paper. (orig.)

Abstract (German)

Die kinetische Gleichung fuer Elektronen, die ueber Coulomb-stoesse und Streuung an Ionenschallwellen und damit zusammenhaengenden Spektren wechselwirken, wird auf ein Gleichungssystem fuer die Energieverteilung und den anisotropen Anteil zurueckgefuehrt. Die Energieverteilung wird fuer die Faelle abgeleitet bei denen Coulombstoesse, 'Runaway' - oder turbulente Heizung vorherrschen. Widerstand, Heizrate und die Dispersionsrelation werden fuer die selbstkonsistente nicht-Maxwell'sche Verteilung stark modifiziert. Die Anwendung des Ionenschalls zur turbulenten Heizung wird diskutiert, andere Transporteffekte werden in einer weiteren Arbeit behandelt. (orig.)
