Abstract:

The influence of strong self-electric fields on the ion resonance instability is examined for a cylindrical nonneutral plasma column immersed in a uniform axial magnetic field B sub 0 e sub z. The analysis is carried out within the framework of a macroscopic cold-fluid model, and electrostatic stability properties are investigated for the case of rectangular electron and ion density profiles. An important conclusion of this study is that the equilibrium self-electric field can have a large influence on stability behavior. Moreover, for a nonneutral plasma column with significant charge neutralization, it is found that the fundamental mode l1 is not the most unstable mode. Rather, higher harmonic perturbations have larger growth rates.
