AbstractThe dynamics of an electron–ion plasma is studied when a mono-energetic relativistic electron beam penetrates the expanding plasma. Combined effects of thermal pressure and ambipolar electrostatic potential are considered for fully relativistic multi-fluids model where the quasi-neutrality assumption is used for a beam–plasma system. Relativistic effects are considered for both density and velocity of the beam fluid. Ion acceleration is depicted through a spike-like structure resulting from non-local charge separation and associated with the beak-down of quasi-neutrality. The beam initial speed is found to enhance the spike amplitude and change its position. Moreover, relativistic effects are particularly found significant for a non-thermal plasma.

Induced Changes

The theories developed to explain the expansion of charged particles from the atmosphere always involve an electric field of charge separation of gravitational origin. A theory is proposed replacing the quasi-neutral sources by a plasma polarization due to the external field of gravity.Assuming that the penetrated Debye clouds are distorted by gravity and hence provide the sources, the induced changes in the correlation function are evaluated. The formalism giving the polarization electric field is verified by using the solution of the differential equations for gravitation correlation in the simplest case of an electron and single ion plasma.
