    Abstract: Gegenstand der Erfindung ist eine Röntgenstrahlungsquelle, in der insbesondere monochromatische Röntgenstrahlung erzeugt werden kann. Außerdem betrifft die Erfindung ein Verfahren zum Erzeugen von Röntgenstrahlung sowie eine Verwendung der Röntgenstrahlungsquelle zur Durchleuchtung von Körpern. Erfindungsgemäß ist vorgesehen, dass in einem Gehäuse (19) eine Metallfolie als Target (11) vorgesehen ist, die mit dem Elektronenstrahl (13) beschossen wird. Hierdurch wird diese zur Aussendung monochromatischer Röntgenstrahlung (18) angeregt, wobei sich hierbei das verhältnismäßig dünnwandige Target (11) soweit verändert, dass der bestimmungsgemäße Gebrauch zur Erzeugung monochromatischer Röntgenstrahlung nicht mehr möglich ist. Deswegen ist vorteilhaft vorgesehen, dass sowohl die Erzeugungseinrichtung (26) für den Elektronenstahl geschwenkt werden kann als auch das Target über Rollen (28, 29) gewickelt werden kann.

    Abstract: In a target structure (100) according to the present invention, a target (102) is provided on a central area of an insulating substrate (101), and a first conductive member (103a) for supplying a voltage to the target is provided on a peripheral area of the insulating substrate which is exclusive of an area overlapping the target and is not covered by the target, so that the first conductive member is in contact with and electrically connected to the peripheral portion of the target. Consequently, it is possible to easily form a voltage supply line to the target without preventing diffusion of a heat generated in the target to the substrate and while suppressing emission of an unnecessary X- ray.
