Abstract

Un tubo catódico provisto de una bobina de desviación del haz de rayos catódicos en el que el rayo de curvatura de la superficie a explorar por el haz es mayor que la distancia de esta superficie al centro de la longitud activa de la bobina de desviación, caracterizado por el hecho de que la bobina de desviación comprende una funda constituida por lo menos de dos capas de materia ferromagnética separadas que rodean prácticamente a la bobina en toda su longitud activa.
