Abstract: The present invention relates to a method of manufacturing a window transparent for electrons of an electron beam (E), in particular of an X-ray source. In order to enable a less costly and elaborate manufacture of such a window and in order to prevent unwanted sharp edges in a window area which may damage the window foil ( 2 ), a method is proposed comprising the steps of:-providing on a surface ( 11 ) of a carrier element ( 1 ) to which a window foil ( 2 ) shall be a fixed a receiving area ( 13, 16 ) for receiving a soldering material ( 3 ) used for fixing said window foil ( 2 ) to said carrier element ( 1 ), said carrier element ( 1 ) comprising a through hole ( 12 ) for the transmission of said electrons (E),-covering said surface ( 11 ) having said receiving area ( 13, 16 ) with a soldering material ( 3 ) such that substantially only said receiving area ( 13, 16 ) is filled with soldering material ( 3 ),-placing said window foil ( 2 ) on top of said surface ( 1 ) and-heating said soldering material ( 3 ) for fixing said window foil ( 2 ) to said surface ( 11 ).

Abstract: The invention relates to a device for generating X-rays (18) comprising an electron source (3) for emitting electrons accommodated in a vacuum space (2), a liquid metal circuit including a liquid metal for emitting X-rays as a result of the incidence of electrons and a pumping means (11) for causing a flow of the liquid metal through a constriction (7) where the electrons emitted by the electron source (3) impinge upon the liquid metal, and a radiation window (12) bounding said constriction (7), which is transparent to electrons and X-rays and separates the constriction (7) from the vacuum space (2). To provide a device for generating X-rays in which a cross-sectional area of the constriction substantially corresponds to an intended, desired cross-sectional area due to a self-regulating process without the need for external or additional components or electronics, it is proposed that said constriction (7) being bounded by a compensation window (13) opposite of said radiation window (12), which separates the constriction (7) from a pressure chamber (14) containing liquid metal provided by said liquid metal circuit via a connection (15), and which, during operation, has a profile (p') as a result of a deformation caused by a pressure in the pressure chamber (14) different from the pressure in the constriction (7) which substantially matches a profile (p) which the radiation window (12) has, during operation, as a result of a deformation of the radiation window (12) caused by a pressure of the liquid metal in the constriction (7).

Abstract: The present invention relates to an X-ray source for the generation of fluorescent X-rays. The X-ray source is realized by an electron source for the emission of electrons and a target which emits X-rays in response to the incidence of the electrons, the target comprising a ring-shaped primary target for the emission of primary X-rays in response to the incidence of the electrons and a secondary target for the emission of fluorescent X-rays in response to the incidence of the primary X-rays. To obtain an enhanced radiance, it is proposed that the primary target comprises a liquid metal channel arranged in a radial direction relative to a central axis, and that a liquid metal circulates in the liquid metal channel during operation of the X-ray source in the radial direction from an inner side to an outer side of the ring-shaped primary target.
