Abstract :
In this paper, a 3D nonlinear perturbative particle simulation code, (BEST) is used to systematically study the stability properties of intense nonneutral charged particle beams with pressure anisotropy (P ⊥ > P||). The most unstable modes are identified and their eigenfrequencies and radial mode structure are determined for axisymmetric perturbations with δ/δθ = 0
