Abstract: An electron multiplying structure for use in a vacuum tube using electron multiplying comprises an input face to be oriented in a facing relationship with an entrance window of the vacuum tube, an output face to be oriented in a facing relationship with a detection surface of the vacuum tube, as well as an ion barrier membrane for shielding off stray ions. The vacuum tube uses electron multiplying having a photocathode capable of releasing electrons into the vacuum chamber when exposed to light, electric field device for accelerating the released electrons from the photocathode towards an anode spaced apart from the photocathode in a facing relationship, as well as an electron multiplying structure. An ion barrier membrane is used in a vacuum tube and/or an electron multiplying structure. The ion barrier membrane is composed of at least one atomic layer containing graphene.
