The target comprises a concave outer surface which is at least a segment of a cylinder (2) having a periodically structured surface (4). The charged particle beam is directed parallel to the axis of the cylinder (2), with the distance of the charged particle beam from the surface being less than or equal to twice the period of the periodically structured surface (4) in a direction perpendicular to the charged particle beam. The width of the charged particle beam in a direction perpendicular to the charged particle beam and parallel to the outer surface of the target is less than twice the period of the periodically structured surface (4) in a direction perpendicular to the charged particle beam.

Abstract: The present invention relates to X-ray generating technology in general, in particular, it relates to an anode disk element (1) for an X-ray generating device (21). The generation of electromagnetic radiation may be considered to be quite inefficient, since a substantial part of energy applied to a focal track is converted to heat rather than X-radiation. Thus, a limiting factor in the operation of X-ray tubes is the cooling of the anode element and more specifically the focal track. In the present invention, an anode disk element is provided, with an improved dissipation of heat from the focal track. Thus, the anode disk element may sustain increased heat while maintaining structural integrity. The anode disk element (1) comprises at least a first surface (2) and a second surface (3), with the first surface (2) comprising a focal track (4) and the second surface (3) comprising a conductive coating (5). The anode disk element (1) is rotatable about a rotational axis (6) with the focal track (4) being rotationally symmetrical to the rotational axis (6). The first surface (2) comprising the focal track (4) and the second surface (3) comprising the conductive coating (5) are adjacently arranged.

Abstract: A rotating envelope radiator has a radiator housing surrounded by an external housing to form an intervening space in which a coolant flows. To prevent the formation, at high rotational frequencies, of reverse flows of the coolant in the intervening space, a flow conductor structure is provided in the intervening space that counteracts the formation of tangential flow components in the coolant.
