Abstract

a. Tube cathodique. b. Un dispositif en forme de bague d'un matériau contenant de la ferrite propre à absorber des rayons X est disposé autour du col du tube cathodique à proximité du dispositif de déviation. c. Pour téléviseurs, etc.at. Cathode ray tube. b. A ring-shaped device of a material containing ferrite capable of absorbing X-rays is arranged around the neck of the cathode-ray tube near the deflection device. vs. For televisions, etc.
