Abstract: A microwave magnetron includes a cathode for emitting electrons, a filament for receiving a filament current to heat the cathode to enable to cathode to emit the electrons, and an anode to which anodic power can be applied to affect a flow of the electrons. An anodic power input receives the anodic power to be applied to the anode, the anodic power being characterized by an anodic current, an anodic voltage, and an anodic impedance, the anodic impedance being a quotient of the anodic voltage and the anodic current. An electromagnet power input receives electromagnet power and applies the electromagnet power to an electromagnet to control an intensity of a magnetic field, the electromagnet power being characterized by an electromagnet current. A controller adjusts at least one of the parameters of the magnetron to affect the flow of electrons while maintaining the anodic impedance constant.
