Abstract

L'invention concerne un canon à électrons pour tube cathodique comprenant, alignés en série le long de l'axe (Z) longitudinal du canon, une pluralité d'électrodes dont une au moins possède une ouverture rectangulaire. Les grands côtés de cette ouverture possèdent des élargissements de forme triangulaire. L'invention est plus particulièrement applicable aux canons à électrons comportant des électrodes formant quadripôle et possédant des ouvertures rectangulaires orientées selon un axe (X) pour certaines électrodes et des ouvertures rectangulaires orientées perpendiculairement à cet axe pour d'autres électrodes.Applications: Tubes à rayons cathodiques.
