Abstract:
介绍了一种新的集成便携式仪器，能够进行现场X射线衍射(XRD)和X射线荧光(XRF)测量。该仪器设计和开发的目的是优化仪器尺寸并且验证嫦娥8号(CE-8)中XRD/XRF光路及低功率实验条件下的可靠性，并能够捕获XRF和XRD信息。同时进行XRD/XRF数据收集是通过使用SDD探测器和HPC探测器对X射线进行计数来实现的。从样品散射的射线光子作为能量和角度步长的函数。该仪器还配备了开发的软件TopMINI及商用软件XRS-FP2，以便在数据收集中提供易于操作的操作，并对材料进行完整和快速的衍射及荧光收集，进行数据分析。
A new integrated portable instrument is introduced, capable of performing on-site X-ray diffraction (XRD) and X-ray fluorescence (XRF) measurements. The instrument was designed and developed to optimize its size and to verify the reliability of the XRD/XRF optical path on Chang’e 8 (CE-8) under low-power experimental conditions, while being able to capture both XRF and XRD information. Simultaneous XRD/XRF data collection is achieved by using SDD detectors and HPC detectors to count the X-rays from the sample, as a function of energy and angular steps. The instrument is also equipped with the developed software TopMINI and commercial software XRS-FP2 to provide user-friendly operation during data collection, and to enable complete and rapid diffraction and fluorescence data acquisition for material analysis.
