STUDY OF CROSSED-FIELD AMPLIFIERS
Abstract
An electron gun which produces a smooth transition from Kino flow near the drift region was designed using a new method of synthesis. An experimental gun was fabricated and tested. The agreement between theory and experiment was good. Noise-figure expressions were derived for cyclotron and space-charge wave amplifiers. These expressions are to be studied to determine the conditions for minimum noise-figure. A five-wave analysis was used to determine the wave amplitudes and phase factors resulting from the interaction between the circuit wave and the beam space-charge waves. The amplitudes of the significant waves were calculated as a junction of beam position for normal experimental conditions. Calculations show that beam-position fluctuation is the most important factor in the noise-figure. A theoretical analysis of crossed-field guns is being carried out to study the effect of a crossed magnetic field on potential minimum stability. A statistical analysis of the cut-off characteristics of the smooth-bore magnetron was completed. The theoretical results were shown to be in close agreement with existing experimental results.
