STUDY OF CROSSED-FIELD ELECTRON DEVICES.
Abstract
The crossed-field noise investigations are concerned with the generation of noise and the characteristics of the beam during the transient interval. The propagation of velocity and current fluctuations along the beam is considered for various regions of a crossed-field device. The formulation of an adequate coupled-mode theory for the gun region has been considered. Velocity-jump noise transformers are considered for use in relatively high-power crossed-field amplifiers. The vacuum system for the crossed-field amplifier has been completely renovated and initial testing indicates that pressures of 5 x 10 to the minus 8th power Torr can be achieved during cathode activation. The abbreviated Kino gun is being tested in the beam analyzer. The aperture-deflection plate system for monitoring current density and velocity of electrons has been located at the exit plane of the gun. Initial investigations indicate that the system in general performs in the desired manner. More detailed investigations are needed to evaluate the accuracy of the system. (Author)
