The invention relates to an X-ray source (1) having an outer housing (3) that can be evacuated, comprising at least one radiation exit window (5), an electron source (7) for emitting an electron beam and an anode (13) for producing X-rays. When the X-ray source is in operation, the anode is present in a vapor phase, wherein the vaporous anode can be produced by evaporating a stock (15) of anode material that is present in a condensed phase by exposure to the electron beam. The invention further relates to a method, in which inside of an outer housing of an X-ray, which can be evacuated, a vaporous anode is continuously formed by bombarding the anode material that is present in a condensed phase with an electron beam. The vaporous anode emits X-rays by interaction with the electron beam. The advantages of the method according to the invention for producing X-rays result analogously to the advantages of the X-ray source according to the invention. |
