Abstract

827,739. Space - charge - wave tubes. GENERAL ELECTRIC CO. April 24, 1956 [April 28, 1955], No. 12523/56. Class 39(1). A space-charge-wave amplifier has a number of electrodes 33, 34, Fig. 1, spaced along the beam and maintained at potentials alternately above and below the mean beam potential, so that a cyclic variation of potential is impressed upon the beam the variation having a wavelength of one-half the plasma wavelength. As shown the cathode 12 forms the inner member of a coaxial-line input resonator closed by grid 16 and the beam after passing accelerating grid 24 traverses the electrodes 33, 34 to output resonator 26. The electrodes 33, 34 are catenoids sealed together by insulating discs 35 to form the envelope and maintained at, say, 100 volts above and below a beam voltage of 1000, the shape chosen produces a nearly sinusoidal variation of potential along the axis. Magnetic focusing is employed. In other forms the electrodes are short cylinders disposed inside the envelope, or a bifilar helix 50, 51, Fig. 3, may be employed. The input and output circuits may also be rhumbatrons or helices. A detailed mathematical discussion of the effect of the voltage variation in producing space-charge-wave amplification, is given.
