Current status of imaging experiments using LEBRA PXR source

X-ray imaging has been a main application of parametric X-ray (PXR) source at Laboratory for Electron Beam Research and Application (LEBRA), Nihon University. The X-ray source is based on the 125-MeV electron linac and has advantages in the monochromaticity, the energy selectivity and the wide irradiation-area. Using such properties of the PXR source, several advanced methods for X-ray imaging have been developed for the PXR application. Especially, computed tomography (CT) and diffraction-enhanced imaging (DEI) are significant for differentiating the PXR source from conventional X-ray sources. In addition, the PXR source has a capability of elemental analysis based on K-edge subtraction (KES) imaging. (author)
