Parametric X-ray Study from Textured Molybdenum Polycrystal

We performed a systematic study on Parametric X-ray radiation from a textured polycrystalline molybdenum target at a 150-MeV electron ring. The measurements were conducted at three observation angles (11.27, 25.89, and 179.85°). The spectral data shows that the spectrum has a unique characterestics: its peak energies depend mainly on the observation angles, its width is much wider than that with the monocrystal case, and its intensities are sometimes comparable to the charactestics Kα of Mo. The observed properties are related to the texture of the polycrystal.
