<p>
The macroscopic warm-fluid model developed by Lund and Davidson [Phys. Plasmas <b>5</b>, 3028 (1998)] is used in the smooth-focusing approximation to investigate detailed stability properties of an intense charged particle beam with pressure anisotropy, assuming small-amplitude electrostatic pertubations about a waterbag equilibrium.
