Abstract (en)
[origin: EP1197470A2] Production of an electron beam-transparent window comprises forming an electron beam-transparent film (1); and joining the film with a holding element (2) via an intermediate layer (4) made of a material having a linear heat expansion coefficient which is similar to the linear heat expansion coefficient of the material of the film but less than the linear heat expansion coefficient of the material of the holding element. The intermediate layer buffers the different linear heat expansion coefficient behavior of the holding element compared to the film. An Independent claim is also included for an X-ray radiator comprising an electron source for emitting electrons and a liquid metal X-ray emitting target having an electron beam-transparent window as separating element between the electron source and the target. Preferred Features: The film, intermediate layer and holding element are joined together in a common step.
