Abstract

In discussing the interaction of naturally occurring particle beams with space plasmas it is convenient to divide the plasma processes involved into two classes — weakly turbulent and strongly turbulent. Naturally occurring particle beams generate a variety of wave modes, and the beam dynamics depend upon several channels of both weakly and strongly turbulent wave-particle interactions. Wave modes generated by the particle beams are divided into two very distinct groups — electrostatic and electromagnetic. The main problem of theoretical interest is to identify the plasma processes that play the major role in the spatial and temporal evolution of the particle beam. The main topic of this paper is a discussion of the role of electrostatic waves in determining the evolution of the auroral electron beam through weakly turbulent processes. This discussion allows the identification of the parameter regime in which strongly turbulent processes are likely to occur. A brief discussion of some wave spectra observed in conjunction with Jupiter’s bow shock is included as an illustration of nonlinear plasma processes.
