Paris-Edinburgh cell applications at HPCAT

ORAL

Abstract

A Paris-Edinburgh cell (model VX-3) has been installed at HPCAT 16BM-B, a bending magnet white X-ray beamline at the Advanced Photon Source. The PE anvil and the heater assembly are specifically designed to contain the sample volume ranging from 0.03 mm$^{3}$ to $>$1.2 mm$^{3}$ while the entire sample volume can be seen through X-ray windows widely open in radial direction. The pressure and temperature of sample can reach up to 7 GPa and 2,300K, respectively. For diffraction experiment, the maximum momentum transfer, Q=4$\pi $sin($\theta )$/$\lambda $, can reach up to $\sim $40 {\AA}$^{-1}$. A real-time white-beam radiography imaging system obtains the absorption contrast images of compressed sample with 7x magnification, 5 $\mu $m image resolutions, and update rate of 0.1 msec to 60 sec per frame. A table top channel-cut monochromator which can provide 30-90 keV monochromatic X-rays is also available for transmission measurement. These series of new instrumental developments are expected to widen the range of user sciences at HPCAT with new opportunities for in-situ measurement of real-time radiography, amorphous and liquid structure, ultrasound velocity, density, electrical resistivity and thermal conductivity.
