摘要
An Inductive Output Tube where, in order to permit the use of coaxial output cavities, the electron beam propagates in first approximation in a radial direction from the cathode. The electron beam is generated by an in first approximation cylindrical cathode, and gated by a consequently in first approximation cylindrical grid. The required drive power is provided by a coaxial input circuit. Depending on the level of a bias voltage, V.sub.g, applied between grid and cathode, the radial electron beam can optionally be operated in modulation classes A, AB, B or C. The modulated electron beam, accelerated by the beam voltage applied between cathode and anode, passes through an in first approximation cylindrical output gap where the modulation interacts with the electromagnetic field of a coaxial output circuit which is optionally connected to one or both ends of the gap between anode and collector. The spent beam is then collected by a radial collector. In this manner the desired use of coaxial cavities, operating in the suitable TE.sub.011 coaxial mode, is achieved.
