Wedge-Driven and Miniature Diamond-Anvil Cells for High-Pressure Optical and X-Ray Diffraction Studies

This paper describes two newly designed diamond-anvil cells. The first one, applicable to powder X-ray diffraction and optical measurements, employs a wedge-driven thrust mechanism for pressure generation. This mechanism enables the fine control of the pressure and remote operation of the cell. The second one, designed for single-crystal X-ray diffraction studies, employs a screw-clamped mechanism for the sake of compactness. The operations for loading and compressing samples with this cell are facilitated by combining it with a wedge-driven cell. Their applications to X-ray diffraction measurements are presented.
