Abstract

TUBO DE RAYOS CATODICOS.COMPRENDE UN CAN/ON ELECTRONICO DENTRO DE UNA AMPOLLA AL VACIO PARA GENERAR AL MENOS UN HAZ ELECTRONICO QUE ES ENFOCADO SOBRE UNA PANTALLA DE PRESENTACION VISUAL PARA FORMAR UN PUNTO LUMINOSO Y QUE ES DESVIADO EN DOS DIRECCIONES PERPENDICULARES ENTRE SI DE FORMA QUE SE ESCRIBE UN RETICULADO O TRAMA EN LA PANTALLA DE PRESENTACION VISUAL. EL CAN/ON ELECTRONICO DISPONE DE UN CATODO QUE ESTA CENTRADO SOBRE UN EJE, UNA PRIMERA REJILLA A CIERTA DISTANCIA DE ESTE A LO LARGO DEL EJE Y UNA SEGUNDA REJILLA A CIERTA DISTANCIA DE LA PRIMERA REJILLA.
