    摘要： An extended interaction output circuit is provided for interacting with a modulated electron beam and for outputting RF electromagnetic energy. The circuit comprises a plurality of linearly disposed cavities having an axially extending beam tunnel to permit the traveling therethrough of the modulated electron beam as well as to couple electromagnetic energy between the successive cavities. Each of the cavities is separated by an annular disk having a hole providing the axial beam tunnel. The hole diameters increase in steps so that the impedance of the successive cavities decreases along the axial extent of the circuit. The diameter of the successive cavities is also increased as the associated width is decreased to maintain the same mid-band resonant frequency. The linearly disposed cavities act as an RF filter having successively tapered impedances to reduce reflections of the electromagnetic energy propagating through the circuit. The gap-to-gap distance between successive cavities is selected to provide a 90 degree phase shift of the beam in order to maintain synchronous operation between the beam and the wave at the mid band frequency.

    摘要： An extended interaction output circuit interacts with a modulated electron beam and outputs RF electromagnetic energy. The circuit comprises a plurality of linearly disposed cavities each having a gap permitting the traveling therethrough of the modulated electron beam. A first pair of the linearly disposed cavities is coupled by a single side cavity, a second pair of the linearly disposed cavities is coupled by a pair of side cavities radially disposed 180 degrees apart, and a third pair of the linearly disposed cavities is coupled by three side cavities radially disposed 120 degrees apart. The linearly disposed cavities act as an RF filter having successively tapered impedances to reduce reflections of the electromagnetic energy propagating through the circuit. RF energy is extracted from the fourth cavity through four waveguide sections that are radially disposed 90 degrees apart.

    摘要： Nonlinear current modulation of a relativistic electron beam is achieved byts propagation without interruption through a resistive wall type of drift tube assembly within a klystron amplifier. Maximized beam current modulation is thereby attained for a beam propagation distance within a shortened drift tube.
