  • Abstract
    A dispersion equation is derived for three-dimensional waves in a warm constant-density cylindrical electron beam confined in a uniform magnetic field. The transverse temperature decreases with radius, from a maximum on axis to zero at the beam edge in a manner that results in rigid-rotor equilibria. The model introduces both an axial thermal parameter TAXN and a transverse thermal parameter TEQ.
