Improvements and considerations for size distribution retrieval from small-angle scattering data by Monte Carlo methods

A method is presented and applied, capable of retrieving form-free particle size distributions complete with uncertainties from small-angle scattering patterns. Special attention is paid to particle observability in the scattering patterns, accurate estimation of data uncertainty and the effect of uncertainty on the resulting size distribution statistics.

Accurate measurements of intrinsic scattering from window materials by use of a vacuum camera

Window materials for small-angle X-ray scattering measurements have been evaluated using a vacuum camera. It is shown that window materials vary in how they scatter the background signal depending on the q range.
