What Types of Space Charge Are Inherent to Different Models of Crossed-Field Devices?

Abstract

In this article four models of crossed-field devices: planar magnetron diode, planar magnetron, magnetron diode and magnetron were described. As well known in crossed-field devices electrons moved by cycloid-like trajectories and formed space charge. The shape of the space charge depends on the model under consideration. In a planar magnetron diode the space charge formed as a flow that is parallel to the electrodes. In a planar magnetron the space charge is not formed and is determined by the anode current only. In a magnetron diode the space charge formed as a flow that is parallel to the electrodes. In a magnetron the space charge is not formed and is determined by the anode current only.
