Cubic-type multi-anvil press

  To study structure and properties of matter under high-temperature and high-pressure conditions, a cubic-type multi-anvil apparatus, SMAP-180 (SPring-8 Multi-Anvil Press with maximum load of 180 ton), is installed. This press is capable to generate pressures up to 12 GPa at room temperature and temperatures up to 2000 K at 6 GPa. With this press, angle-dispersive X-ray diffraction (ADX) measurements and density measurements by means of X-ray absorption are possible. The ADX method has the advantage of accuracy in intesity and resolution over energy-dispersive X-ray diffraction method, which is commonly used for multi-anvil presses. In the ADX, diffraction pattern is collected using an imaging plate (IP). A radial slit system reduces background X-rays from materials that surround the sample without increasing the data acquisition time too much. For adjustment and real-time observation, a CCD camera with an X-ray image intensifier can be used. Thanks to the intense, high-energy monochromatic X-rays up to 70 keV, precise X-ray diffraction measurements in a wide Q range are possible. The high-energy X-rays will also allow us to study heavy elements. For absorption measurements, two ionization chambers are used.
