Abstract
Improvements introduced in a cathode ray tube comprising, in an ampoule in which a vacuum has been made, at least one system of electrodes, to generate at least one electron beam, whose electrode system comprises, centered along a common geometric axis, a cathode, a control electrode and an anode, and in addition at least two electrodes, mainly cylindrical, to focus the aforementioned electron beam, characterized in that the internal diameter of the aforementioned cylindrical electrodes, taken from the cathode, increases in such a way that, from an electronic optical point of view, there is a substantially insignificant difference in smaller diameters between said electrodes.
