| Research Abstract |
A multi-axis oscillation system for a diamond anvil cell (DAC) is developed for the improvement of quality in X-ray powder diffraction profiles. The large opening conical DAC is also newly designed for the system. We installed and tested the system in the beam lines (BL04B2 and BL10XU) at SPring-8. The Gandolfi camera-like motion given for the sample in DAC contributes a drastic improvement for the statistics of the particles satisfying the Bragg condition.
