  • Using the three slit collimation system with a divergent beam simplifies the design of a small angle X-ray scattering (SAXS) cameras and improves both flux and stability. To achieve the required low angle and a high spatial resolution, the collimation system must be optimized in the design and operation phases. Simulation of a slit divergent camera yields optimal distance between the beam defining slits and optimal distance between sample and detector at which the maximum SAXS resolution is achieved with a minimal parasitic scattering for any length of the SAXS camera. The narrower the beam defining slits and the longer the total camera length, the smaller the minimum resolvable angle and the higher the attainable resolution. © 2012 - IOS Press and the authors.
