Design and Simulation of Extended Interaction Cavities for a Ka-band Multi-beam Klystron.

This article reports about the design approach, electromagnetic simulation and analysis results of high-frequency ladder-type input, output, and intermediate RF cavaties for Ka-band multi-beam extended interaction klystron. Several parameters of the cavity, such as quality factor, shunt impedance, etc., have been investigated by the assistance of electromagnetic software CST microwave studio. [ABSTRACT FROM AUTHOR]
