Abstract

Un magnétron comprend une anode (1) à l'intérieur de laquelle est montée coaxialement une cathode constituée d'une barre (2), dotée d'éléments situés sur sa surface et assurant l'émission primaire ainsi que l'émission secondaire. L'élément assurant l'émission primaire se compose d'au moins un disque plat (3) constitué d'une feuille ultra mince d'un métal réfractaire, au milieu duquel se trouve un orifice. L'élément assurant l'émission secondaire se compose d'au moins un manchon cylindrique (4) en métal d'émission active. Le diamètre externe du disque (3) est plus grand que celui du manchon (4) d'une valeur située dans la plage comprise entre 0,1 et 0,2 de la valeur de la distance interélectrode. Les faces terminales du disque voisin (3) et du manchon (4) sont en contact. L'invention, du fait de la création de l'intensité de champ électrique nécessaire à l'obtention de l'émission autoélectronique suffisante pour exciter le magnétron, permet le démarrage instantané du magnétron sans chauffage préalable de la cathode.
