Plasma effects of superthermal electrons in the ionosphere
Abstract
The dynamics of superthermal electrons in the ionosphere is investigated, using numerical and analytical methods to analyze the rates of collisional degradation of the auroral electrons and photoelectrons in the upper atmosphere and the plasmasphere. Particular attention is given to high-frequency plasma fluctuations in ionosphere related to the presence of photoelectrons, and to their consequences. The role of collective effects in the process of interaction between the high-energy electron beams and the lower ionosphere is discussed together with the effects of superthermal electrons on radio-wave propagation in ionosphere.
