We present a multi-purpose radiation furnace designed for x-ray experiments at synchrotrons. The furnace is optimized specifically for dark-field x-ray microscopy (DFXM) of crystalline materials at beamline ID06 of the European Synchrotron Radiation Facility. The furnace can reach temperatures above 1200 °C with a thermal stability better than 10 °C, with heating and cooling rates up to 30 K/s. The non-contact heating design enables samples to be heated either in air or in a controlled atmosphere contained within a capillary tube. The temperature was calibrated via the thermal expansion of an α-iron grain. Temperature profiles in the y and z axes were measured by scanning a thermocouple through the focal spot of the radiation furnace. In the current configuration of the beamline, this furnace can be used for DFXM, near-field x-ray topography, bright-field x-ray nanotomography, high-resolution reciprocal space mapping, and limited powder diffraction experiments. As a first application, we present a DFXM case study on isothermal heating of a commercially pure single crystal of aluminum.
我们展示了一种为同步加速器上的X射线实验设计的多用途辐射炉。该炉是专门为欧洲同步辐射装置ID06光束线的晶体材料暗场X射线显微镜（DFXM）进行了优化。该炉能够达到1200°C以上的温度，热稳定性优于10°C，加热和冷却速率高达30 K/s。非接触式加热设计使样品能够在空气中或毛细管内的可控气氛中加热。通过α-铁晶粒的热膨胀对温度进行校准。通过将热电偶扫描穿过辐射炉的焦点来测量y轴和z轴上的温度分布。在光束线的当前配置中，该炉可用于DFXM、近场X射线形貌、明场X射线纳米断层扫描、高分辨率倒易空间映射以及有限的粉末衍射实验。作为首个应用，我们展示了一个关于商业纯铝单晶等温加热的DFXM案例研究。
