Abstract

An x-ray tube includes an electron emitter to emit an electron beam; and a multilayer anode including a first anode layer facing the electron beam and a second anode layer facing away from the electron beam. The first anode layer includes a first anode material to generate a braking radiation via the electron beam and the second anode layer includes a second anode material to generate a further x-ray radiation via the braking radiation. The further x-ray radiation is relatively more monochromatic than the braking radiation and wherein the first anode layer and the second anode layer adjoin in a planar manner.
