Stability properties of azimuthally symmetric perturbations in an intense electron beam. Memorandum report
The Vlasov-Maxwell equations are used to investigate the stability of azimuthally symmetric perturbations (e.g., sausage and hollowing modes) of an electron ion beam immersed in a resistive plasma. The perturbed space charge and plasma current are treated self-consistently for any value of the plasma conductivity. A similar analysis of the hose instability is also carried out. The analysis is carried out for the 'loss-cone' distribution function in which all of the beam electrons have the same value of energy and the same value of axial canonical momentum. In the high conductivity regime, the system is shown to be strongly destabilized by a sufficiently large value of the fractional current neutralization.
