Abstract

Un dispositivo perfeccionado para visualizar imágenes sobre una pantalla de fósforo, que incluye una ampolla con vacío interior que tiene paredes delantera y trasera separadas, extendiéndose sustancialmente al menos una guía de enfoque de haz de electrones paralelamente a dichas paredes frontal o delantera y trasera, teniendo dicha guía de enfoque paredes que sirven para confinar entre ellas un haz de electrones dirigido en la guía de enfoque, y medios para generar el menos un haz de electrones y dirigir cada haz a una guía de enfoque independiente; caracterizado por medios de depuración de haz de electrones entre dichos medios generadores de haz de electrones y dicha guía de enfoque para eliminar del haz generado los electrones que están situados y tienen un vector velocidad tal que si se les permitiese permanecer en dicho haz incidirían sobre una pared de dicha guía de enfoque durante el recorrido a lo largo de la guía de enfoque.
