    摘要: A self-biasing element is formed by coupling an electron accumulator to a collector stage of a linear-beam microwave tube with a base which has a selected resistance. The electron accumulator has a secondary emission coefficient less than one and is positioned to intercept a portion of the electrons in the electron beam of the linear-beam microwave tube. The electron accumulator thus acquires a negative voltage whose magnitude is controlled by selecting the base resistance and the radial and axial position of the self-biasing element within the collector. Various arrangements of self-biasing elements and collector stages are disclosed which improve the efficiency and RF performance of the microwave tube.

    摘要: Lossy slabs are provided in linear-beam tubes such as coupled-cavity TWTs and klystrons to produce a more level tube response over its full operating band, and to eliminate oscillations at the upper cut-off frequency in the TWTs. The slab thicknesses are selected to produce a substantially non-resonant field of about one-quarter wavelength within the slab when the tube is operated within its passband. The slabs are formed from a dielectric material with a conductive mixture of at least about 15%.
