Combination of in situ laser heating with single-crystal X-ray diffraction (scXRD) in diamond anvil cells (DACs) provides a tool to study crystal structures and/or chemistry of materials at simultaneous high pressures and high temperatures. Here, we describe the first dedicated single-crystal X-ray diffractometer coupled with double-sided laser heating (dsLH) system. The scXRD/dsLH setup was developed for the P02.2 Extreme Conditions Beamline at PETRA III and became available for general users in 2017. It enables the collection of reliable scXRD data at simultaneous high pressure and high temperature. We demonstrate the performance of the setup on example of studies of iron and chromium nitrides.
在金刚石对顶砧（DAC）中结合原位激光加热与单晶X射线衍射（scXRD），提供了一种在同时处于高压和高温条件下研究材料晶体结构和/或化学性质的工具。在此，我们描述了首个与双面激光加热（dsLH）系统联用的专用单晶X射线衍射仪。scXRD/dsLH装置是为PETRA III的P02.2极端条件光束线开发的，并于2017年可供普通用户使用。它能够在同时处于高压和高温的条件下收集可靠的scXRD数据。我们以铁和氮化铬的研究为例展示了该装置的性能。
