Abstract
PURPOSE: To avoid voltage breakdowns or arcs from occurring between an inner screen and an outer screen by disposing the formed separated apart from the latter by a specified distance and by producing a microwave cavity at part of a reflector, connected to the two screens and the peripheries of the screens. CONSTITUTION: A microwave cavity 10, having a reflective surface and providing a partially open cavity wall, a first metallic screen 8 covering the partial opening, and a second metallic screen 6 located inside a cavity 4 and spaced from the first metallic screen 8 by a distance of 50mm to 65mm are provided. This reduces microwave leakage and prevents arcs.
