Intense electron beam propagation across a magnetic field
Abstract
The propagation of an intense electron-ion beam across an applied magnetic field is considered. In the absence of the applied field, the beam system is in a Bennett equilibrium state that involves electrons with both large axial and thermal velocities and a cold stationary space charge neutralizing ion species. Typical parameters under consideration are V(sub o) approx. 1 MV, I approx. 5 kA, T(sub e) approx. 100 keV, and beam radii approx. 1 cm. It was found that in the intense beam regime, the propagation is limited due to space charge depression caused by the deflection of the electron beam by the transverse field. This critical field is of the order of the peak self-magnetic field of the electron beam which is substantially higher than the single particle cut-off field.
