Abstract:

Discovered by a particle simulation is a "super" ion acoustic double layer. The potential jump reaches to a surprisingly large amplitude, which is far beyond the electron thermal energy, say, by more than order of magnitude. An electron beam that gains this energy is generated on the downstream side, of which the spectrum is in good agreement with that of the observed auroral precipitating electrons.
