Abstract

ESTRUCTURA DE CAN/ON ELECTRONICO EN LINEA PARA UN TUBO DE RAYOS CATODICOS EN COLOR.LOS TAMAN/OS EFECTIVOS DE ABERTURAS DE LOS ELECTRODOS FINALES DE ENFOQUE Y ACELERADOR DE LA ESTRUCTURA SON INCREMENTADOS ALARGANDO LAS ABERTURAS, EXPANDIENDO SUS BORDES EXTERIORES Y RODEANDOLOS CON UN CERCO ELEVADO PERIFERICO QUE EQUILIBRE LA ASIMETRIA INTRODUCIDA EN ELLAS POR EL AGRANDAMIENTO. LAS SEPARACIONES ENTRE LAS ABERTURAS PUEDEN TENER UNOS RADIOS TALES QUE SU ALTURA DE CENTROS SEA MENOR QUE LA ALTURA EN LOS BORDES. EL CERCO ELEVADO DEL ELECTRODO ACELERADOR FINAL ES GENERALMENTE MAS ALTO QUE EL DEL ELECTRODO DE ENFOQUE.
