Abstract:

Several one dimensional models are derived which approximate the relativistic flow of high current beams in diodes. Using these models as a starting point, a diode for a 1 GW beam for a 35 GHz gyrotron oscillator is easily designed. Keywords Diodes Microwave Spacial Velocity Helical Gyrotrons Eelctron beams Transverse Momentum Trajectory. The analysis is based on four one dimensional planar or conical models for electron flow in diodes. The planar models are relativistic and can be used to obtain electrode shapes for space charge limited flow. The conical models shed light on important geometric effects. Principally, it is shown that the space charge limited current is larger in realistic geometries than in the corresponding planar configuration.
