Abstract
The invention relates to a device for generating X-rays (). The device has a source () for emitting electrons () accommodated in a vacuum space (). The X-rays are emitted by a liquid metal as a result of the incidence of the electrons. The liquid metal flows through a constriction () where the electrons emitted by the source impinge upon the liquid metal. The constriction is bounded by a thin window (), which is made from a material which is transparent to electrons and X-rays and which separates the liquid metal in the constriction from the vacuum space, and by a wall () opposite to the window. According to the invention, the wall () has a profile (p) which matches a profile (p') which the window () has, during operation, as a result of a deformation of the window caused by a pressure of the liquid metal in the constriction (). Thus, it is achieved that the constriction has a predetermined intended cross-sectional area, and a decrease of the flow velocity and an accompanying excessive increase of the pressure at the location of the deformation of the window are prevented.
