We report a new diamond anvil cell apparatus for in situ synchrotron X-ray diffraction measurements of liquids and glasses at pressures from ambient to 5 GPa and temperatures from ambient to 1300 K. This portable set-up enables in situ monitoring of melting of complex compounds, and the determination of the structure and properties of melts under moderately high-pressure and hightemperature conditions relevant to industrial processes and magmatic processes in Earth’s crust and shallow mantle. The device was constructed according to a modified Bassett-type hydrothermal diamond-anvil cell design with a large angular opening ( = 95°). In this paper, we report the successful application of this device to record in situ synchrotron X-ray diffraction of liquid Ga and synthetic PbSiO3 glass to 1100 K and 3 GPa.
