TRANSVERSE-WAVE HIGH-POWER TUBE.
Abstract
Research and development work has begun on a novel type of traveling-wave power amplifier tube, employing transverse-wave interaction between the negative synchronous wave and a circuit wave on a balanced structure. The theoretical advantage in this arrangement is the possibility of high-power amplification with high overall efficiency, due to the lack of longitudinal or transverse velocity modulation in the spent beam. No d-c pumping process is involved, so that such a tube would be free from noiseorbit pumping or beam blowup, such as occurs in the Larmotron and the Bass tube. Theoretical and experimental work on a scale model of a twisted, finned, ridged, circular waveguide has shown that an appropriate dispersion curve, as well as adequate interaction impedance, can be obtained at S-band. Design work is continuing with the objective of demonstrating the feasibility of a 1-kw CW output power, at an efficiency of at least 60%, using a depressed collector. (Author)
