ABSTRACT: "Colour cathode ray tube in-line electron gun structure incorporating deep saddle accelerating electrode" In a color cathode ray tube having an in-line electron gun with overlapping OFF lenses, the accelerating electrode apertures are critically enlarged to deepen the saddles between adjacent apertures in order to balance the asymmetry of the tensing field caused by the focusing electrode, and eliminate beam spot distortion at the screen due to field asymmetries in the focus region.
