Abstract

Un dispositivo para la desviación de un haz de electrones en un tubo electrónico, particularmente un tubo captador de imágenes, que comprende un yugo anular de material magnético, que tiene una serie de núcleos dirigidos radialmente hacia dentro de un material magnético, los cuales están provistos en sus extremos interiores de piezas polares en forma de segmentos anulares que encierran un espacio de desviación, caracterizado porque se han previsto al menos un par de núcleos dispuestos diametralmente opuestos con bobinas de desviación para la desviación horizontal así como para la desviación vertical, estando situada cada bobina de desviación, vista desde el espacio de desviación, completamente detrás de la pieza polar asociada, estando cada uno de los espacios que hay entre cada dos piezas polares situadas adyacentes puenteado por una pieza intermedia de material no magnético.
