摘要： 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).

摘要： 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).

摘要： The present invention relates to an X-ray source for the generation of fluorescent X-rays comprising an electron source (1) for the emission of electrons (6) and a target which emits X-rays (10) in response to the incidence of the electrons (6), said target comprising a ring-shaped primary target (2) for the emission of primary X-rays (9) in response to the incidence of the electrons (6) and a secondary target (3) for the emission of fluorescent X-rays (10) in response to the incidence of the primary X-rays (9). To obtain an enhanced radiance, it is proposed that the primary target (2) comprises a liquid metal channel (8) arranged in radial direction relative to a central axis (4), and that a liquid metal circulates in the liquid metal channel (8) during operation of the X-ray source in radial direction from an inner side (13) to an outer side (14) of said ring-shaped primary target (2).
