Ray-tracing analysis of capillary concentrators for macromolecular crystallography

The use of capillary concentrators as X-ray condensers specifically for macromolecular X-ray diffraction experiments using synchrotron radiation is evaluated. Monocapillary and polycapillary designs are assessed by ray-tracing analysis to evaluate how effectively these capillary concentrators can increase the X-ray intensity onto a 50 micro m crystal.
