Abstract
An ultraviolet generator powered by a microwave source, such as a magnetron, is disclosed. The generator has an elongated inner element, preferably an electric conductor in the form of a polished metallic rod or an electrodeless bulb. An outer conductor, formed from an electrically conductive mesh or a perforated conductive material, is arranged around the inner element. One or more electrodeless ultraviolet bulbs are arranged, preferably radially, around the inner element within the outer conductor. The inner element and outer conductor are arranged for direct coupling to the microwave power source using a waveguide. The inner element is joined to the outer conductor by a disk positioned at the end of the generator opposite to the power source.
