Abstract: A two-dimensional x-ray scattering camera includes a source, an optic, a detector, and a pair of collimating blocks. The source emits x-ray beams that are reflected by the optic towards a sample. The detector detects scattering from the sample, the pair of collimating blocks is positioned between the optic and the detector to collimate the beam. A bottom surface of one block is substantially parallel a top surface of the other block, and the blocks are rotatable relative to the beam about a pivot. The system forms a two-dimensional beam that is symmetric about the primary beam axis at the detector position, regardless how the beam is collimated by the collimating blocks. The system therefore eliminates smearing and can be used for anisotropic small angle scattering at high resolution and low Qmin.

Abstract: A multi-beam x-ray system includes an x-ray source which emits x-rays and a housing with a first part and a second part. The second part is moveable relative to the first part and includes a plurality of optics of different performance characteristics. Each optic, through the movement of the second part relative to the first part, is positioned to a working position so that the optic receives the x-rays from the x-ray source and directs the x-rays with the desired performance attributes to a desired location.

Abstract: An x-ray optical system for producing high intensity x-ray beams. The system includes an optic with a surface formed by revolving a defined contour around a revolving axis that is different than the geometric symmetric axis of the optic. Accordingly, the system may use a source that has a circular emission profile or a large source to provide increased flux to a sample.

Abstract: An x-ray optical device delivers an x-ray beam with variable convergence. The convergence or the divergence of the x-ray beams varies over different parts of the reflector. The device may include an adjustable aperture to further select the convergence or divergence. The adjustable aperture selects the convergence angle by selectively occluding a portion of the x-ray beams.

Abstract: An x-ray optical device includes an optic and an adjustable aperture that selectively occludes a portion of an x-ray beam. The adjustable aperture may be positioned between the optic and a sample and may be integrated with the optic or located in close proximity to the optic. The adjustable aperture enables a user to easily and effectively adjust the convergence of the x-rays. In doing so, the flux and resolution of the x-ray optical device can be optimized by using an optic having the maximum convergence allowed for all potential measurements, and then selecting a convergence for a particular measurement by adjusting the aperture.

Abstract: A multilayer mirror 1 that has elliptical reflection faces and provides a divergent angle &dgr; of X-rays, is included. The elliptical reflection faces of the multilayer mirror 1 have two focal points. When an X-ray source 2 is arranged at one focal point A, and X-rays that are diverged from the X-ray source 2 are reflected at the multilayer mirror 1, the reflected X-rays converge on another focal point B. The X-ray source 2 is arranged at one focal point A of the multilayer mirror 1. Additionally, a distance L2 from the center of the reflection faces of the multilayer mirror 1 to another focal point B (in other words, convergent point of reflected X-rays) is set to make a convergent angle &thgr;c of X-rays at the focal point B nearly twice as great as the divergent angle &dgr;. With the above-noted configuration, both small angle resolution and intensity of incident X-rays to a sample may be optimized, and small angle scattering may be performed with high precision.
