Energy dispersive x‐ray diffraction from high pressure polycrystalline specimens using synchrotron radiation
TLDR
Energy dispersive diffraction from high-pressure specimens with a synchrotron radiation source is described in this article, where a remote-controlled diffraction stage which has greatly facilitated alignment of the highpressure sample in the radiation beam is discussed.Abstract:
Energy dispersive diffraction from high‐pressure specimens with a synchrotron radiation source is described. A remote‐controlled diffraction stage which has greatly facilitated alignment of the high‐pressure sample in the radiation beam is discussed. An experimental diffraction pattern and theoretical relative intensities are compared.read more
