Cathodes for multibeam klystron, klystron containing such cathodes and method of manufacturing such cathodes

摘要

The present invention relates to the cathodes intended for multibeam klystrons. These cathodes are impregnated cathodes made on a single impregnated porous matrix 16. These cathodes are separated from one another by a compact layer 15 of a refractory material carried by the matrix 14. A focusing electrode 19 is placed near the surface of the compact layer 15. IMAGE
