We have conducted high-resolution inelastic X-ray scattering (IXS) measurements of supercritical metallic fluids at high temperature and high pressure using synchrotron radiation at SPring-8 in Japan. We developed a high-pressure vessel for IXS measurements pressurized by He gas up to 196 MPa and installed the highpressure gas apparatus in the experimental hutch. After the installation IXS experiments were carried out for supercritical fluid Hg to study atomic dynamics in the metal-nonmetal transition near the liquid-vapor critical point. Next the apparatus is used to study atomic dynamics in the semiconductor-metal transition in supercritical fluid Se. In this article we report the experimental technique at high temperature and high pressure in detail, and show recent results using the technique.
