Parametric X rays (PXR) are a new type of X ray that are generated by crystal electron interactions. The Laboratory for Electron Beam Research and Application (LEBRA) at Nihon University generates PXR using a double crystal system generating electrons from a 100 MeV class LINAC. LEBRA PXR has potential for use as a wavelength tunable, ultra high bright X ray source with a macro /micro pulse structure. LEBRA PXR has an energy dispersion in the horizontal axis, assumed to be 0.2% in the experimental window, but can be used as monochromatic X ray source for diffraction using a simple slit system. A diffraction experiment was successfully carried out by applying an 11 keV, or 1.1273 Å, LEBRA PXR. Near perfect crystals, such as graphite used for a monochromator showed sharp diffraction peaks. Clear, transparent mineral quartz and fluorapatite crystals also showed sharp diffraction peaks, while the diffraction peaks from clear calcite and silicon powder were not detected. Possible reasons for the lack of diffraction peaks from these materials are discussed. LEBRA PXR has potential for use in studies on the diffraction of other materials, and is therefore, expected to be a useful tool for crystallographic analysis.
