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, is reported. This portable setup enables in situ monitoring of the melting of complex compounds and the determination of the structure and properties of melts under moderately high pressure and high temperature conditions relevant to industrial processes and magmatic processes in the 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 (gθ = 95°). This paper reports the successful application of this device to record in situ synchrotron X‐ray diffraction of liquid Ga and synthetic PbSiO 3 glass to 1100 K and 3 GPa.
