Abstract

955,728. Magnetrons. LITTON INDUSTRIES Inc. March 15, 1961 [April 11, 1960], No. 9494/61. Headings H1D and H1W. A cavity magnetron has a coupling iris 22, Fig. 1, e.g. dumbbell-shaped, extending through the wall of the anode block 16 and an envelope 12 which is made of ceramic material, e.g. 98% pure beryllium oxide, at least in the region covering the coupling iris. Other suitable envelope materials are aluminium oxide, zirconium oxide or titanium oxide. The magnetron shown is of the multi-cavity vane type with reentrant end caps 14 for receiving the magnet poles and which serve also to support and to provide electrical connections to the cathode 20 and to provide the usual end hats for constraining the electrons in the interaction space. The magnetron may alternatively be of the single cavity interdigitated anode segment type. The magnetron 10, Fig. 3, is mounted in a heat dissipating aluminium solid body 38 which is divided into two sections separated by a dielectric member 44. Passages 42 in the container provide waveguides for leading off the microwave energy from the coupling iris or irises. Liquid coolant may be passed through internal passageways of the body 38, or the body may have hollow sections, an associated vapour condenser converting vapour coolant to liquid during the cooling process.
