Abstract

CAÑON ELECTRONICO QUE COMPRENDE UN CATODO COMPUESTO POR UN EJE CATODICO (53) RODEADO DE UNA PANTALLA REFLECTORA DEL CALOR (56). UNA PIEZA DE CONEXION (55) SUJETA AL EXTREMO DE CABECERA DEL EJE CATODICO (53). UN RECEPTACULO (59) QUE CONTIENE MATERIAL EMISOR DE ELECTRONES (60) SE SITUA DENTRO DE LA PIEZA DE CONEXION (55). EL EJE DEL CATODO (53) SE SUSPENDE EN LA PANTALLA REFLECTORA DE CALOR (56) POR MEDIO DE ALAMBRES DE SUSPENSION (57), ESTANDO SUJETO CADA ALAMBRE A LA PANTALLA REFLECTORA CON UN EXTREMO QUE ESTA LO MAS PROXIMO POSIBLE A LA CABECERA DE LA PANTALLA REFLECTORA (56) Y CUYO OTRO EXTREMO ESTA SITUADO ENTRE LA PIEZA DE CONEXION (55) Y RECEPTACULO (59).
