PROCEEDINGS OF THE 12TH INTERNATIONAL CONFERENCE ON SYNCHROTRON RADIATION INSTRUMENTATION – SRI2015 | 2016

High-pressure pair distribution function (PDF) measurement using high-energy focused x-ray beam

Xinguo Hong; Lars Ehm; Zhong Zhong; Sanjit K. Ghose; Thomas S. Duffy; Donald J. Weidner

In this paper, we report recent development of the high-pressure pair distribution function (HP-PDF) measurement technique using a focused high-energy X-ray beam coupled with a diamond anvil cell (DAC). The focusing optics consist of a sagittally bent Laue monochromator and Kirkpatrick-Baez (K–B) mirrors. This combination provides a clean high-energy X-ray beam suitable for HP-PDF research. Demonstration of the HP-PDF technique for nanocrystalline platinum under quasi-hydrostatic condition above 30 GPa is presented.


ICXOM23: International Conference on X-ray Optics and Microanalysis | 2016

High-energy X-ray focusing and high-pressure pair distribution function measurement

Xinguo Hong; Lars Ehm; Zhong Zhong; Sanjit K. Ghose; Thomas S. Duffy; Donald J. Weidner

In this paper, we report recent progress in high-energy X-ray focusing by using Kirkpatrick-Baez (K–B) mirrors in combination with a sagittally bent Laue monochromator. This combination of optics provides a high flux X-ray beam, which can significantly reduce the data acquisition time for high-pressure pair distribution function (HP-PDF) measurements using the diamond anvil cell (DAC). Demonstration of the HP-PDF technique for the compression/relaxation of nanocrystalline platinum at high pressures is presented.
