Intense Relativistic Cyclotron Beams and Disk Beams for High Power Millimeter Wave Generation

Abstract

High power millimeter wave has many potential applications, such as advanced radar, detection, and imaginations. Currently, most high power millimeter wave sources operate at the Cerenkov or transition-time mechanism and are excited by linear annular intense relativistic electron beams (IREBs). In this paper, two other kinds of IREBs, the cyclotron annular beam and the disk beam are introduced to generate high-power millimeter waves. The former determines the performance of fast wave sources, and the latter is a kind of promising sheet beam used in radial slow wave sources. Both of the two kinds of beams are emitted from explosive emission cathode (EECs).
