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 ).
