Abstract

Dispositivo de tubo de rayos catódicos, que tiene un cañón electrónico que está constituído, al menos por un cátodo, una grilla de control y un ánodo colector y en que se toman medidas para aumentar la pendiente de la curva característica de modulación , caracterizado porque el electrodo de control tiene una o más aberturas auxiliares situadas entre la superficie emisora de electrones del cátodo y partes del ánodo colector que son recubiertas con una sustancia que tiene un factor de emisión secundaria más elevada que la unidad, estando el electrodo de control rodeado por un ánodo auxiliar para la descarga de los electrones secundarios.
