Scientific paper

The response of a plasma to the transmission of an electron beam whose density is commensurable with the plasma density is studied analytically and numerically with reference to active electron-beam injection experiments in space (e.g., the ARAKS experiment). In the framework of a 1D model it is shown that, behind the leading front of the beam, nonlinear plasma oscillations are excited which assure a mean charge and current neutralization of the beam. The oscillation amplitude is maximal in the case of a sharp leading front; oscillations are absent in the case of a slow 'switch-on' of the beam. The degree of the deceleration of the beam as a whole, depending on the beam-to-plasma density ratio, is calculated.
