ABSTRACT:
An X-ray image amplifier tube designed with an input screen having a photocathode and with a detection screen which is opposite the latter and a short distance away for detection of a photo-electron beam which is generated by X-ray input image signals and is amplified in the tube. The detection screen is provided with a conversion coating for converting an image-carrying photo-electron beam into a potential excursion and to this end contains, for example, an amorphous selenium coating or a porous KCl coating. A variable potential can be applied both over the vacuum gap between the photocathode and the conversion coating and over the conversion coating itself and, as a result of this, high image brightness dynamics can be achieved without image disruption.
