X-RAY SOURCE WITH ROTATING LIQUID-METAL TARGET

An X-ray beam (3) is generated in an interaction zone (4) of an electron beam (5) and a target (6), the target being an annular layer of a molten fusible metal in an annular groove (7) of a rotating anode assembly (8). The groove (7) has a surface profile which prevents the molten metal to leave in...

Beschreibung
Zusammenfassung:	An X-ray beam (3) is generated in an interaction zone (4) of an electron beam (5) and a target (6), the target being an annular layer of a molten fusible metal in an annular groove (7) of a rotating anode assembly (8). The groove (7) has a surface profile which prevents the molten metal to leave in radial direction and in the directions along the rotation axis. The liquid-metal target (6) forms a circular cylindrical surface due to the centrifugal force acting thereupon. The linear velocity of the target is preferably higher than 80 m/s. In a vacuum chamber, a replaceable membrane made of carbon nanotubes is installed in the X-ray beam path and a protective shield with apertures for the electron beam entry and for the X-ray beam exit is arranged around the interaction zone (4).
