Abstract

Es wird ein Röntgenstrahler mit einem Flüssigmetall-Target und einer Elektronenquelle (3) zur Emission eines Elektronenstrahls (4) in ein Fenster (23) eines Leitungsteils (51), durch das im Betriebszustand das Flüssigmetall-Target fließt, beschrieben, der sich insbesondere dadurch auszeichnet, dass das Leitungsteil (51) durch einen ersten Leitungsabschnitt (10, 20), der das Fenster (23) aufweist und durch den das Flüssigmetall-Target fließt, sowie einen zweiten Leitungsabschnitt (30, 40) gebildet ist, durch den ein Kühlmittel strömt und der so an dem ersten Leitungsabschnitt befestigt ist, dass der Bereich der Einwirkung des Elektronenstrahls auf den ersten Leitungsabschnitt gekühlt wird.

Figure 00000001
An X-ray emitter with a liquid metal target and an electron source (3) for emitting an electron beam (4) into a window (23) of a line part (51), through which the liquid metal target flows in the operating state, is described characterized in that the line part (51) is formed by a first line section (10, 20), which has the window (23) and through which the liquid metal target flows, and a second line section (30, 40) through which a coolant flows and which is attached to the first line section such that the area of action of the electron beam on the first line section is cooled.
