Diffractometer for diamond anvil cell
In order to perform high pressure experiments, a diffractometer for diamond anvil cell (DAC) is installed. This system is designed for both single crystal and powder X-ray diffraction measurements. The system mainly consists of three parts, sample positioning stages, detectors, and a microscope. On the basic setup of sample stages including an ω-axis, translations and an arc-stage, various components can be mounted; a χ-φ circle goniometer, a 4K He closed cycle cryostat, a simple DAC holder. Two types of detectors, an imaging plate (IP) and a charge coupled device (CCD) detector, are equipped. The IP is the size of 400 × 400 mm2, and the sample-detector distance can be changed from 200 mm to 730 mm. The CCD detector is mounted on the 2θarm. The area size is 70 × 70mm2, and the sample-detector distance can be changed from 100 mm to 200 mm. The sample mounted on the diffractometer can be monitored by the microscope. With use of the microscope, the sample pressure can be also measured by the ruby luminescence method.
