CROSSED FIELD MICROWAVE TIME DELAY TUBE FEASIBILITY STUDY.

Abstract

A six month program of theoretical and experimental investigation to determine the feasibility of developing a crossed-field microwave tube to operate as a variable time delay device was carried out in the Crossed-Field Oscillator Group of the Raytheon Microwave and Power Tube Division. A broadband delay coupler was constructed and tested to determine the limits on bandwidth, insertion loss and signal power level. A large bandwidth fast cyclotron wave synchronous condition was obtained, but with a pronounced reduction in coupling because of the high interception current on the delay circuit. Low coupling made it impossible to obtain accurate data concerning beam saturation levels or insertion loss in the experimental coupler. A computer study of the beam optics in a variable drift space region determined the optimum design for the drift electrode shapes and potential profile for a delay variation of at least 150 nanoseconds.
