最近开发了一种便携式系统；它结合了X射线荧光(XRF)和X射线衍射(XRD)技术，可以同时进行无机材料的元素分析和物相鉴定。采用低功率(30W)风冷铜阳极X射线源，配备多毛细管半透镜，提供平行的X射线束。该系统的设计没有机械动作，其配置允许分析任意形状的物体；该仪器特别适用于文物不可移动和/或呈现不规则表面和形状的文化遗产应用中的材料识别。在这篇文章中，我们介绍了仪器的设计和首次测试测量。特别是，我们的结果表明，有可能确定样品中存在的主晶相，并在相对较短的时间内进行分析，从30分钟到1或2小时。
A portable system has been recently developed; it combines x-ray fluorescence (XRF) and x-ray diffraction (XRD) techniques, allowing simultaneous elemental analysis and phase identification of inorganic materials. A low power (30 W) air-cooled Cu anode x-ray source is used, equipped with a polycapillary semi-lens to provide a parallel x-ray beam. The system has been designed without mechanical movements and its configuration allows the analysis of objects with arbitrary shapes; the instrument is particularly suitable for material identification in cultural heritage applications where artefacts are non-moveable, and/or exhibit irregular surfaces and shapes. In this article, we present the design of the instrument and the first test measurements. In particular, our results show that it is possible to identify the main crystalline phases present in the samples and to perform the analysis in relatively short times, from 30 min to 1 or 2 h.
