Abstract
A conventional (non-relativistic) magnetron provides megawatt-levels of power. The magnetron includes a fourteen vane slow wave structure that surrounds a fourteen turn helical cathode. An upstream coaxial waveguide is surrounded by a dish-shaped flange that accommodates a reflector chamber in communication with an upstream void and a downstream interaction chamber. The vanes of the slow wave structure are shaped to define fourteen resonant chambers therebetween with each of the resonant cavities having a wedge portion in communication with a neck portion.
