Abstract
[[abstract]]The interaction of a hollow, cylindrical, rotational, electron beam with a dense magnetized plasma is studied by means of a two fluid theory. The rotational electron beam is such that each beam electron gyrates about the beam axis under the influence of an axial magnetic field in addition to its translational motion. It is shown that, under certain conditions, the beam currents may be fully neutralized by counter flowing plasma currents whose subsequent decay can produce an efficient retarding force on the beam. Beam trapping, plasma heating and detailed energy transfer processes are discussed[[fileno]]2010126010002[[department]]物理
