This thesis examines parametric x-radiation (PXR) generated by Silicon and Lithium Fluoride monochromators, including the first observation of PXR from Lithium Fluoride. Parametric x-radiation may be described as the Bragg scattering of virtual photons associated with relativistic electrons as they pass through single crystal monochromators. As the photons interact with the crystal lattice they produce x-rays which meet the Bragg condition lambda = 2dsintheta sub B, where theta sub B is the angle between the electron beam and the crystal plane. PXR data were collected from Silicon and Lithium Fluoride crystals using a SiLi detector. The locations of the energy peaks are compared to the locations predicted by theory and the intensity ratios between the peaks are also compared to the theoretical ratios. The PXR energy observed was as predicted by theory for Silicon and Lithium Fluoride monochromators. The observed peak intensity ratios for Silicon were not in agreement with intensity ratios predicted by theory. Intensity ratios observed from Lithium Fluoride were in agreement with the predicted value. jg p2
