Focusing synchrotron radiation using a polycapillary half-focusing X-ray lens for imaging

An imaging system based on a polycapillary half-focusing X-ray lens (PHFXRL) and synchrotron radiation source has been designed. The focal spot size and the gain in power density of the PHFXRL were 22 mu m (FWHM) and 4648, respectively, at 14.0 keV. The spatial resolution of this new imaging system was better than 5 mm when an X-ray charge coupled device with a pixel size of 10.9 x 10.9 mm was used. A fossil of an ancient biological specimen was imaged using this system.
