摘要：

A sample holder for X-ray diffraction experiments on supercritical fluids has been constructed. The holder with Be windows of 2 mm thickness has endured the inner sample pressure of up to 10 MPa, and the temperature of the sample has been changed in the range of 0-60-degrees-C. Preliminary diffraction experiments for a supercritical CO2 fluid and a high-pressured CO2 liquid near the critical point have been carried out using the sample holder and a detector with an imaging plate. The total accumulation time was about 1 h. Use of the present equipment enables X-ray diffraction experiments on supercritical fluids to be carried out very easily.
