Abstract

An auxiliary beam deflection yoke device in a color television image reproduction system incorporating a color image tube of the multi-beam shadow mask type provided with a main beam deflection yoke excited by substantially sawtooth currents respectively at repeat frequencies of lines and fields to scan an image graticule on a screen having a multiplicity of luminescent dot groups of different color output; characterized in that the auxiliary beam deflection yoke mounted next to said main deflection yoke and excitable as a function of the temperature and the angle of deflection of the bundles to modify the effective centers of deflection of said electron beams, comprises a ferromagnetic core substantially circular; a pair of horizontal windings located in toroidal form about said core and extending respectively about one half of said core on diametrically opposite sides thereof, said horizontal windings being interconnected so as to produce when excited a deflection field of transverse beam substantially vertical; a pair of vertical windings located toroidal around said core and extending respectively about one half of said core on diametrically opposite sides thereof, and displaced circumferentially with respect to said core by approximately 90º from said pair of horizontal windings, said vertical winding being interconnected so as to produce, when excited, a substantially horizontal beam deflection field.
