    Wave-particle interaction as a possible source of electron heating in ExB fields driven instabilites

  • Original language description

    An anomalous electron heating in the ExB fields driven instabilities is usually studied under the Farley-Buneman (FB) instability conditions. We study how the electron heating evolves out of the FB limit for different types of ion-neutral collisions. Electron temperature is easily determinable in our simulations: because of Maxwellian velocity distribution of electrons, their temperature relates to the second moment of the velocity distribution. We observe the strongest electron heating for the ion-neutral elastic collisions, while the largest electrostatic potential fluctuations are for the ion-neutral charge exchange collisions. Wave spectra, obtained from the Fourier transform of electrostatic potential, suggest wave-particle interaction around electron thermal velocity which can provide energy transfer between the wave and electrons and heat them up. Since the parameters of our simulations can be related as scaled ionospheric conditions, our results can be useful for explaining som
