Abstract

Lámpara o tubo de descargas caracterizado porque los electrodos están provistos de una pantalla puesta a un potencial apropiado con relación al electrodo correspondiente para ser positivo con relación al electrodo que funciona como cátodo y que delimita alrededor de este electrodo un espacio de sección relativametne pequeña con relación al de la descarga.Lamp or discharge tube characterized in that the electrodes are provided with a screen set at an appropriate potential in relation to the corresponding electrode in order to be positive in relation to the electrode that functions as a cathode and that delimits a space with a relatively small section around this electrode in relation to to the discharge.
