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.

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.

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.

The present invention provides an x-ray beam conditioning system with a Kirkpatrick-Baez diffractive optic including two optical elements, of which one of the optical elements is a crystal. The elements are arranged in a side-by-side configuration. The crystal can be a perfect crystal. One or both diffractive elements can be mosaic crystals. One element can be a multilayer optic. For example, the multilayer optic can be an elliptical mirror or a parabolic mirror with graded d-spacing. The graded d-spacing can be either lateral grading or depth grading, or both.

An x-ray optical system includes a multiple corner optic assembly including an adjustable aperture assembly located in close proximity to the optic assembly. The adjustable aperture assembly enables a user to easily and effectively adjust the convergence of an incident beam of x-rays or the optic focal spot size. The adjustable aperture assembly may further enable a user to condition x-rays of one wavelength and block x-rays of another wavelength and thereby reduce the amount of background radiation exhibited from x-rays of more than one wavelength.
