The research of the influence of ferromagnetic insert on density distribution of low-power electron beam

Abstract

The paper considers transportation of low-power high-current charge compensated electron beam in axially symmetric magnetic field and in non-symmetrical magnetic field of a reverse current distributor with ferromagnetic inserts arranged behind the collector. The influence of geometrical dimensions and properties of the material of cylindrical inserts (solid and hollow) on beam density distribution on the collector was numerically studied. It was shown that electron beam density section and target distribution may be controlled by ferromagnetic inserts.
