Abstract: A cathode ray tube, in particular a color tube, in which two or more electron beams are produced, focused, and converged on a picture display screen. A part of each electron beam is intercepted and reflected against a given part of the neck as a result of which the potential thereof rapidly adjusts at an equilibrium value after switching on the tube.
