Abstract
A grid for an electron tube with an axial beam which includes an apertured part through which the electrons of the beam are intended to pass. The grid is in the form of a bell and is made of a single material. The apertured part is located at the top of the bell but is placed in the bottom of a hollow so that the electrons passing through the grid around its periphery are focused onto the axis. Such a grid may find particular application to IOT-type tubes.
