Claim 8:
9. A method for generating X-ray radiation comprising an electron bombardment of a liquid-metal target (6) on a surface of a rotating anode assembly (8) and output of an X-ray beam (3), generated in an interaction zone (4) of an electron beam (5) with the liquid-metal target, through an X-ray window (2) of a vacuum chamber (1), said method comprising:
the target (6) formation by centrifugal force as an annular layer of molten fusible metal on a surface of an annular groove (7) implemented in the rotating anode assembly (8), a part of the rotating anode assembly is made in the form of a disk (12) having peripheral portion in the form of an annular barrier (13), and the annular groove is implemented on the surface of the annular barrier facing the axis of rotation (10),
providing the molten fusible metal not to be ejected in the radial direction and in both directions along the axis of rotation (10) by a chosen profile of the annular groove surface, and
debris suppression by means of a debris shield (27) rigidly mounted to surround the interaction zone (4), said shield having a first opening (28) forming an entrance for the electron beam (5) and a second opening (29) forming an exit for the X-ray beam (3) with
the liquid-metal target rotating with a linear velocity of more than 80 m/s, wherein
a vector of the linear velocity of the target in the interaction zone and at least one of the two openings are located on different sides of the plane passing through the interaction zone (4) and the axis of rotation (10).
