Abstract
A cathode ray tube arrangement comprising an electron gun having electrodes centered along a first axis that produce an electron beam with a crossover point on the first axis and electronic optics means centered along a second axis that focus the electron beam, said first and second axes cutting each other at an acute angle, characterized by the fact that the point of intersection of the first axis and the second axis coincides with the crossing point and that the cathode ray tube it comprises a diaphragm having an opening that is centered relative to the second axis, with said opening passing less than a quarter of the electron beam, the first axis cutting the diaphragm out of said opening.
