Abstract
Perfeccionamientos introducidos en un tubo de rayos catódicos que comprende medios para generar un haz de electrones, medios para enfocar dichos haz de electrones en un punto sobre un anticátodo que se extiende en el tubo sustancialmente perpendicular a la dirección longitudinal del mismo, y medios para soportar un electrodo de enfoque asociado con dichos medios de enfoque, constituyendo dicho electrodo de enfoque, sobre su cara enfrentada con el anticátodo, una lente electrostática en combinación con un recubrimiento eléctricamente conductor dispuesto sobre el interior de la ampolla del tubo, caracterizados porque los medios que soportan el electrodo de enfoque consisten en un número de miembros de soporte eléctricamente conductores que se extienden principalmente en sentido axial, que están rodeados por el mencionado recubrimiento conductor
