INVESTIGATION OF LARGE-SIGNAL TRAVELING-WAVE TUBES.
Abstract
A digital computer program is used to obtain solutions to a two-dimensional nonlinear analysis for large-signal traveling-wave devices. Velocity distributions near saturation are shown for a number of cases. Derivation of the equations for a density function method to be used in the solution of large-signal phenomena in multistream microwave devices is given. Experimental phase shift data obtained on a velocity tapered TWA is presented. The characteristics of a different transducer to be used on the tube tapered by 70 percent are shown. Techniques for the brazing process to be used in the depressed potential collector are described. The method worked out is shown to be quite satisfactory from an electrical as well as a mechanical standpoint. The present status of digital computer programs for solid- and hollow-beam guns is described. Future modifications to make the programs more versatile are discussed. Noise figure data for the Crestatron is given. A minimum noise figure of approximately 19 db has been observed for typical values of gain to be encountered in a Crestatron. (Author)
