Abstract

A radiation source for generating multi-chromatic, particularly di-chromatic, x-radiation has at least one cathode and an anode for generating x-ray bremsstrahlung and a target surrounded by the cathode for converting the x-ray bremsstrahlung incident on the target into fluorescence radiation. The target is composed of different materials in sections and the sections can be selectively irradiated with the x-ray bremsstrahlung.
