Abstract
A detector for a small-angle x-ray diffraction system uses curved readout strips shaped to correspond to the expected intensity distribution of x-rays scattered by the system. This expected intensity distribution may be a series of concentric circles, and each of the strips has a shape that approximates a section of an annulus. The strips may be positioned on a substrate such that a center of curvature of the curved strips is located along an edge of a readout region within which the strips are located or, alternatively, at a geometric center of the readout region. The detector may have a signal readout system that uses a delay line or, alternatively, a multichannel readout system. The detector may make use of electron generation via interaction of the diffracted x-ray beam with a gas in a gas chamber, or through interaction of the diffracted beam with a semiconductor material.
