Kinetic studies of temperature anisotropy instability in intense charged particle beams

This paper extends previous analytical and numerical studies [E.A. Startsev, R.C. Davidson and H. Qin, Phys. Plasmas 9, 3138 (2002)] of the stability properties of intense nonneutral charged particle beams with large temperature anisotropy (T

) to allow for non-axisymmetric perturbations with part/partthetas ne 0. The most unstable modes are identified, and their eigenfrequencies and radial mode structure are determined
