Abstract

Synchrotron X-ray measurements with Paris-Edinburgh (PE) press have been utilized to study high-pressure behaviors of solids and liquids in various scientific fields such as physics, earth sciences, and materials sciences. PE press allows compression of large sample volumes of up to 2mm in both diameter and length up to 7 GPa and 2000 K. In addition, our recent development of opposed-anvil-type double-stage large volume cell enables us to compress moderate size of sample (0.23 mm in diameter and 0.15 mm in length) to ultrahigh pressure conditions of >100 GPa. PE press have been used for many high-pressure synchrotron X-ray researches such as X-ray imaging and tomography, X-ray diffraction, and X-ray absorption. This talk will present an overview of PE press high-pressure experiments and X-ray researches with PE press.
