    Abstract: For the generation of multiple-energy X-ray radiation, an X-ray tube (10) for generating multiple-energy X-ray radiation includes an anode (12) and a filter (14). At least a first (16) and a second focal spot position (18) are offset from each other in an offset direction (20) transverse to an X-ray radiation projection direction. The filter includes a first plurality (22) of first portions (24) with first filtering characteristics for X-ray radiation and a second plurality (26) of second portions (28) with second filtering characteristics for X-ray radiation. The filter is a directional filter adapted in a such a way that at least a first X-ray beam (30) emanating from the first focal spot position at least partly passes through the filter unit via the first portions, and a second X-ray beam (32) emanating from the second focal spot position passes obliquely through the first and the second portions when passing through the filter unit.

    Abstract: The present invention relates to the generation of multiple X-ray beams (26). In order to provide a facilitated X-ray source with the capability of increased tube power for providing coherent radiation, for example in differential phase contrast imaging (DPCI), a multiple X-ray beam X-ray source (10) is provided with an anode structure (12) and a cathode structure (14). The anode structure comprises a plurality of liquid metal jets (16) providing a plurality of focal lines (18). The cathode structure provides an electron beam structure (20) that provides a sub e-beam (22) to each liquid metal jet. The liquid metal jets are each hit by the sub e-beam along an electron-impinging portion (24) of the circumferential surface that is smaller than half of the circumference.

    Abstract: An x-ray source is described. During operation of the x-ray source, an electron source emits a beam of electrons. This beam of electrons is focused to a spot on a target by a magnetic focusing lens. In particular, the magnetic focusing lens includes an immersion lens in which a peak in a magnitude of an associated magnetic field occurs proximate to a plane of the target. Moreover, in response to receiving the beam of focused electrons, the target provides a transmission source of x-rays.

    Abstract: This invention provides a source of x-ray flux in which x-rays are produced by e-beams impacting the inner walls of holes or channels formed in a metal anode such that most of the electrons reaching the channel impact an upper portion of said channel. A portion of the electrons from this primary impact will generate x-rays. Most of the electrons scatter but they continue to ricochet down the channel, most of them generating x-rays, until the beam is spent. A single channel source of high power efficiency and high power level x-rays may be made in this way, or the source can be of an array of such channels, to produce parallel collimated flux beams of x-rays.

    Abstract: Periodic spatial patterns of x-ray illumination are used to gather information about periodic objects. The structured illumination may be created using the interaction of a coherent or partially coherent x-ray source with a beam splitting grating to create a Talbot interference pattern with periodic structure. The object having periodic structures to be measured is then placed into the structured illumination, and the ensemble of signals from the multiple illumination spots is analyzed to determine various properties of the object and its structures. Applications to x-ray absorption/transmission, small angle x-ray scattering, x-ray fluorescence, x-ray reflectance, and x-ray diffraction are all possible using the method of the invention.
