Abstract
A four-cavity, large-sized beam tunnel, G-band extended interaction Klystron (EIK) is here proposed. A three-hole coupling cavity has been optimized to ensure a sufficient beam-wave interaction. The beam conductance and the total quality factor of each cavity have been analyzed to evaluate the stability of the beam-wave interaction for a 0.2-A beam current and 14.5-kV operating voltage. The particle-in-cell (PIC) simulation results show that the maximum output power is 134.5 W, with a gain of 30.3 dB and an efficiency of 4.6%, with a 3-dB bandwidth of 1 GHz.
