Abstract
Perfeccionamientos en tubos de rayos catódicos mediante dispositivo de bloqueo de los iones, caracterizándose por el hecho de que se sitúa sobre la trayectoria del haz electrónico una delgada hoja, entre la fuente de los electrones y la pantalla sensible, permitiendo de esta manera el paso de los electrones, pero eliminando a los iones.
