Anomalous heat transport in a weakly collisional magnetized plasma with ion acoustic turbulence

The kinetics of subthermal and thermal electrons in a weakly collisional ma gnetized plasma with ion-acoustic turbulence is described in detail. The pe rturbations of the pressure, density, and temperature of the plasma via the absorption of a high-frequency electromagnetic field due to inverse bremss trahlung and also the electron charge and heat fluxes are determined. Turbu lent noises are shown to suppress heat transport both along and across the magnetic field.
