CA 2319620
The invention concerns an electronic tube grid with axial beam (50), comprising an open-worked part (23) designed to be traversed by the beam (50) electrons. The grid is shaped like a bell (22) and is made of a single material. The open-worked part (23) is located at the bell top (21) but is placed at the base of a hollow part so that the electrons passing through the grid at its periphery are focused on the axis. The invention is particularly applicable to IOT.
La présente invention est relative à une grille pour tube électronique à faisceau (50) axial. Elle comporte une partie ajourée (23) destinée à être traversée par les électrons du faisceau (50). Elle est en forme de cloche (22) et est mono-matériau. La partie ajourée (23) est située au sommet (21) de la cloche mais est placée au fond d'un creux pour que les électrons traversant la grille à sa périphérie soient focalisés sur l'axe. Application notamment aux tubes de type IOT.
