A conductive body is positioned at a null in a discharge device which utilizes a TM210 cavity to reduce direct coupling from the microwave coupling means, e.g., slot of the cavity. A plurality of TM110 cavities are ganged together, and a single discharge tube extends through all of the cavities.Other References
