Abstract
In this paper the design of a novel small-angle X-ray scattering cryst al camera for high-resolution measurements is given. The instrument is based on a double-crystal diffractometer using two Laue crystals. Bea ms of narrow angular width in the collimator and the analyzer parts of the system are obtained by utilizing the ''Super''-Borrmann effect. T heoretical calculations on multiple-beam diffraction were used to find an appropriate set of reflections. Feasibility studies on different m ultiple-beam Laue diffraction cases showed a collimation of 1.5 x 10(- 5) rad at 8 keV X-ray energy, corresponding to a maximum dimension D(m ax) = 5 mum that could be studied in small-angle scattering.
