Abstract

A radiation converter has a radiation absorber for generating photons dependent on the intensity of incident x-ray radiation, a photocathode arranged downstream of the radiation absorber in the radiation propagation direction at a distance therefrom and serving for generating electrons dependent on the photons emerging from the radiation absorber, a device for accelerating the electrons emerging from the photocathode onto an electron detector for generating electrical signals dependent on the impinging electrons, an electron multiplier arranged between the photocathode and the electron detector, the electrons emerging from the photocathode being multiplied by the electron multiplier.
