Abstract
Un tubo de rayos catódicos perfeccionado que comprende, en una envuelta de vidrio en la que se ha hecho el vacío, un cañón de electrones para generar un haz de electrones y un blanco para recibir el haz de electrones, cuyo cañón de electrones consiste al menos en un cátodo que está centrado sustancialmente alrededor de un eje y la superficie de emisión del cual es sustancialmente perpendicular a dicho eje, una primera rejilla y una segunda rejilla, constituyendo la primera rejilla en cooperación con el cátodo y la segunda rejilla lentes de electrones no rotacionalmente simétricas, caracterizado porque la primera rejilla en cooperación con el cátodo constituye una lente de electrones multipolo, la cual es esencialmente una primera lente tetrapolar o cuadripolo, y en cooperación con la segunda rejilla constituye también una lente de electrones multipolo la cual es también esencialmente una segunda lente cuadripolo y que está girada 90º con respecto a la primera lente cuadripolo.
