Abstract

L'invention concerne une cathode de type cathode de frittage (C1) comportant une partie terminale en forme de coquille (35) composée d'une partie de pointe conique (31) disposée sur une arête latérale faisant face à une anode, et d'une partie de base cylindrique (33) disposée sur l'autre arête latérale. Ladite partie terminale (35) forme une partie de rayonnement électronique destinée à émettre des électrons, et contient un métal particulaire à point de fusion élevé, une couche d'aluminium (43) recouvrant au moins partiellement la surface du métal (41), et un oxyde métallique (45) servant de substance émettant aisément les électrons. Ladite partie terminale (35) est formée par mélange d'un composé (carbonate métallique) contenant un métal servant de substance émettant aisément les électrons au métal (41) revêtu de la couche d'aluminium (43), transformation en oxyde métallique (45) par traitement thermique, et frittage du mélange.
