New configuration of a virtual cathode oscillator for microwave generation
- Laboratory of Beam Technology and Department of Electrical Engineering, Nagaoka University of Technology, Nagaoka, Niigata 940-21 (Japan)
A new configuration of a virtual cathode oscillator is proposed for high-power microwave generation. Analysis and simulation are carried out to investigate the characteristics of this configuration. In the numerical simulation, the microwave output power of {similar_to}564 MW is obtained with an electron beam of 300 keV in electron energy and 15 kA in beam current, giving a beam-to-microwave efficiency of {similar_to}12.5%. The significant features of the new configuration are (1) the microwave output power is not affected by an electron energy spread up to 6%; and (2) no significant change of the oscillation frequency is observed when the beam current changes from 10 to 20 kA. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
