Abstract:
The amplifier described in this paper utilizes a waveguide as the propagating circuit. The interaction takes place between a spiraling electron beam and the dominant waveguide mode in the presence of an axial magnetic field. Desirable features of this device are high power capabilities and high frequency. A magnetron injection gun with radial electric field is used to produce a spiraling beam. The beam is passed through a discontinuity in the radial electric field and into a tapered magnetic field, resulting in a hollow beam with the individual electrons having the correct properties for interaction. An analysis is carried out describing the limiting perveance characteristics of a rotating electron beam. The amplifier is designed to operate under pulsed conditions at X-band. Theoretically gains in the order of 10 db are possible with the efficiency near 30 per cent.
