Abstract
Un tubo de descarga eléctrica que comprende una envuelta que tiene un eje principal, una pantalla de presentación y un sistema de cañones de electrones para producir una pluralidad de haces de electrones y hacer converger los haces sobre la pantalla de presentación, comprendiendo el sistema de cañones de electrones primeros medios de electrodo para generar los haces de electrones, estando situados los primeros medios de electrodo a lo largo de ejes paralelos al eje principal de dicho tubo, segundos medios de electrodo situados a lo largo de la trayectoria de los haces de electrones entre los primeros medios de electrodo y la pantalla de presentación, cuyos segundos medios de electrodo comprenden un último electrodo situado en el lado adyacente a la pantalla de presentación y un electrodo precedente asociado, cuyos electrodos en el uso constituyen un campo de lente que enfoca los haces de electrones simétricamente, y terceros medios de electrodo entre los medios de electrodo primeros y segundos para formar un campo de lente asimétrico para hacer converger los haces de electrones sobre la pantalla de presentación.
