COMBINED ENERGY DISPERSIVE XAS AND ANGLE DISPERSIVE XRD FOR HIGH PRESSURE STUDIES AT ID24, ESRF

Abstract

We present a new experimental set-up for combined angle dispersive XRD and energy dispersive XAS measurements at high pressure successfully commissioned on the dispersive XAS beamline (ID24) at the ESRF. We illustrate preliminary results on a test experiment performed on ZnCl₂ in the pressure and temperature range up to 6GPa and 650 K respectively. XAS at Zn K-edge and XRD data of three different phases of ZnCI₂ are shown.
