摘要：

Three small-angle scattering cameras based on mirror/monochromator optics, a circular Bragg-Fresnel (BF) lens, and a microcollimation system combined with a double-focusing mirror have been tested for microfocusing applications. In order to reach a focal spot less than or equal to 10 mu m, a microcollimation system provides a flexible solution for medium-resolution applications. When using a glass capillary as a collimation system, a minimum s-value of 5.10(-2) nm(-1) was attained. Scanning small-angle x-ray scattering (SAXS) patterns from a poly(tetramethyl-p-silphenylene)-siloxane spherulite and a 40-mu m polyethyl- eneterephthalate fiber were obtained in a few seconds per pattern with a 4 mu m diameter beam at a wavelength of lambda = 0.095 nm.
