Abstract

The self similar expansion of a two-ion plasma is investigated via a multi-fluid model. Our aim is to elucidate the effect of secondary ions on the plasma expansion front, in combination with energetic (suprathermal) electrons in the background. Considering an analytically tractable situation (namely, assuming secondary ions to represent a minority population), and adopting a kappa-type distribution function for the suprathermal electrons, it is shown that energetic electron contribute to acceleration of the expansion front and to an increase in the associated electric field.
