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 PITIFXRL were 22 μm (FWHM) and 4648, respectively, at 14.0 keV. The spatial resolution of this new imaging system was better than 5 μm when an X-ray charge coupled device with a pixel size of 10.9 x 10.9 μm was used. A fossil of an ancient biological specimen was imaged using this system. [ABSTRACT FROM AUTHOR]
