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.Improvements in cathode ray tubes by means of an ion blocking device, characterized by the fact that a thin sheet is placed on the path of the electron beam, between the source of the electrons and the sensitive screen, thus allowing the passage of electrons, but eliminating ions.
