INVESTIGATION OF LARGE-SIGNAL KLYSTRON AND TRAVELING-WAVE DEVICES.
Abstract
A general nonlinear two-dimensional interaction theory is employed to analyze Brillouin flow in the presence of large-signal r-f on the circuit. Finite values of axial magnetic field and radial variations of both the circuit and space-charge fields are assumed. The present status of the nonlinear boundary-value problem solution for electron and plasma devices is described. The computer program is ready for checkout. Considerations in the initiation of two experimental programs are described. One is a study of beam stability in the presence of large r-f fields, while the second deals with velocity distribution effects on the start-oscillation conditions of BWO's. Results of cold tests made on several ring-and-bar circuits are summarized. Calculations on a phase-focused ring-and-bar tube are initiated. Two digital computer programs for the solution of electron guns are being worked on. The first deals with magnetron injection guns and is shown not to be reliable as yet. The second one is concerned with relativistic electron beams. This program is ready for checkout. Preliminary work on the design of a tube for checking the noise properties of a beam obtained from a magnetron injection gun is described. Design considerations for a noise transformer are given.
