Abstract

A sort of color cathode ray tube, having a in-wire electronic gun, including the 3 cathodes from the 3 electronic beams to the fluorescent screen disposed in the ray, and the upper lens for focusing said 3 electronic beams on the fluorescent screen, including the primary lens the 2 cylindrical electrodes disposed in internal axially on the tube, being subject the 2 cylindrical electrodes to different voltages, satisfying the following inequality: 2S + 14.6 < T < 25.3; 4.1 < S; being S the pitch among the electronic beams on the primary lense on the central axises of the 3 adjacent electronic beams, in unit of mm, and T the outer diameter of the neck of the vacuum tube sleeve housing the in-wire electronic gun.
