INVESTIGATION OF LARGE-SIGNAL TRAVELING-WAVE TUBES.
Abstract
Research was continued on a study of large signal traveling-wave tubes. Extensions on the two-dimensional large-signal analysis for klystrons and traveling-wave tubes are presented. Space-charge effects and the effects of stream subdivisions and the number of charge groups chosen are shown in a number of graphs. The work on the nonlinear theory of multistream microwave devices by a density function method is summarized. An improved method of handling the coupling between positive and negative velocity regions was worked out. Experimental test results on several phase-focused tubes are presented. Efficiency enhancements obtained by this method as well as a simple depressed potential collector are described. The test results obtained on the ring-and-bar tube before it had to be rebuilt are also listed. Several additional minor changes made on the solid beam digital computer program are described. Futhermore the status of the program for solution of magnetron injection guns is discussed. (Author)
