Abstract We propose a new low-impedance high power microwave source based on the axial transit time effect, i.e. a low-impedance axial transit-time oscillator. The analysis and simulation are carried out to investigate the characteristics of this new configuration. In the numerical simulation, the microwave output peak power of 6 GW is obtained with an electron beam in the electron energy 580 keV and in the beam current 20 kA. The diode impedance is 29Ω. The power of the input electron beam is 11.6 GW. The beam-to-microwave power conversion efficiency is 51.7%. The frequency is 3.9 GHz by numerical simulation.
