The monochromatic X-ray source based on parametric X-ray radiation (PXR) was developed by using the electron beam from the 125-MeV linac at Nihon University. The X-ray generating system consists of two silicon perfect-crystal plates to offer a wide tunability. The system has actually been providing the energy dispersive monochromatic X-ray beam in the region of 6 to 20 keV, using Si(111)-plane for the target and the second crystals. Since the X-ray beam from the PXR generator has rather high energy resolution and coherency, X-ray absorption fine structure (XAFS) measurement and phase-contrast imaging are possible applications of PXR. Actually, preliminary experiments on energy dispersive XAFS measurement and refraction-contrast imaging have been successfully carried out using the PXR beam.
