在这项研究中，我们开发了一个用户友好的自动粉末衍射测量系统的Debye-Scherrer几何形状使用毛细管样品在光束线BL 02 B2的SPring-8。该测量系统由六个一维固态（MYTHEN）探测器、一个紧凑的自动进样器、宽范围温度控制系统和一个气体处理系统组成。该系统能够对多个样品的衍射图案的温度依赖性进行自动测量。我们在MYTHEN系统中引入了两种测量模式，并开发了用于样品环境的新附件，如气体处理系统。测量模式和附件可以在25 K至1473 K的扩展温度范围内以及各种气体气氛和压力下提供原位和/或时间分辨测量。使用参考材料（NIST CeO 2 674 b和Si 640 c），V2 O3和Ti 2 O3，和纳米多孔配位聚合物的调试和性能测量的结果。由AIP出版社出版。
In this study, we developed a user-friendly automatic powder diffraction measurement system for Debye-Scherrer geometry using a capillary sample at beamline BL02B2 of SPring-8. The measurement system consists of six one-dimensional solid-state (MYTHEN) detectors, a compact autosampler, wide-range temperature control systems, and a gas handling system. This system enables to do the automatic measurement of temperature dependence of the diffraction patterns for multiple samples. We introduced two measurement modes in the MYTHEN system and developed new attachments for the sample environment such as a gas handling system. The measurement modes and the attachments can offer in situ and/or time-resolved measurements in an extended temperature range between 25 K and 1473 K and various gas atmospheres and pressures. The results of the commissioning and performance measurements using reference materials (NIST CeO2 674b and Si 640c), V2O3 and Ti2O3, and a nanoporous coordination polymer are presented.
