High Pressure Studies Using Energy Dispersive Diffraction of High Energy X-Rays.

Abstract

The smooth continuum of white radiation produced by a 160 kV generator has been combined with Energy Dispersive X Ray Diffraction (EDXRD) and a Drickamer type cell for high pressure studies. The theory of EDXRD is briefly reviewed and the advantages of the technique, high penetration and improved resolution, are discussed. The results of measurements of the compressibility of TiB up to 80 kbar arre reported. The technique developed has also been used with the high energy radiation produced by the UK Synchrotron Radiation Source Wiggler. A simple diffractometer, designed and built for energy dispersive diffraction of such radiation is described. Results of measurements of the compressibility of TiB2 up to 130 kbar are presented. Keywords: Energy dispersive diffraction; High energy X rays; Synchrotron radiation; Wiggler; High pressure; Drickamer type cell; TiB, TiB2.
