Abstract  According to the intensity distribution of synchrotron radiation source focused by toroidal mirror at the Beijing synchrotron radiation biological macromolecule station, the theoretical modeling of Beijing synchrotron radiation source is developed for capillary optics. With this theoretical modeling, the influences of configuration curve of polycapillary X-ray lens on transmission efficiency and working distance are analyzed. The experimental results of transmission efficiency and working distance at the biological macromolecule station are in good agreement with theoretical results.
