Abstract

Dispositivo de rayos catódicos que comprende una envoltura evacuada que contiene un blanco que tiene una superficie operativa cóncava de forma cilíndrica o sustancialmente cilíndrica y un espacio de control de trayectoria de haz que se extiende hacia dicha superficie de blanco, medios estacionarios para producir un campo de control de trayectoria en dicho espacio para producir el pasaje de un haz electrónico que debe incidir sobre dicho blanco en la dirección de una posición seleccionada de la generatriz del blanco, campo de control que es giratorio alrededor de un eje de rotación ubicado sobre el lado cóncavo del mencionado blanco y paralelo al mismo a fin de seleccionar o variar la posición deseada de la generatriz, y medios para dirigir un haz electrónico hacia dicho campo con una componente de velocidad paralela a la superficie operativa de blanco a lo largo, o sustancialmente a lo largo, de un plano que contiene dicho eje de rotación y dicha generatriz seleccionada del blanco.
