论文摘要
在现有的元素表征技术中，粒子诱导的X射线发射（PIXE）和能量色散X射线（EDX）光谱是不同科学和技术领域中最广泛使用的两个。在这里，我们介绍了在Salamanca的CentrodeLáserespulsados进行的第一个定量激光驱动的Pixe和激光驱动的EDX实验研究。由于它们具有紧凑性和可移植性的潜力，激光驱动的粒子源对材料科学应用非常吸引人，尤其是对于材料分析技术。我们证明了通过与电子和质子共同辐照产生的X射线信号的可能性，以识别样品中的元素。我们表明，仅使用质子束，我们可以通过激光驱动的Pixe分析成功获取有关样品结构的定量信息。这些结果铺平了迈向基于激光驱动的粒子源的材料元素分析的紧凑和多功能设备开发的道路。
Among the existing elemental characterization techniques, Particle Induced X-ray Emission (PIXE) and Energy Dispersive X-ray (EDX) spectroscopy are two of the most widely used in different scientific and technological fields. Here we present the first quantitative laser-driven PIXE and laser-driven EDX experimental investigation performed at the Centro de Láseres Pulsados in Salamanca. Thanks to their potential for compactness and portability, laser-driven particle sources are very appealing for materials science applications, especially for materials analysis techniques. We demonstrate the possibility to exploit the X-ray signal produced by the co-irradiation with both electrons and protons to identify the elements in the sample. We show that, using the proton beam only, we can successfully obtain quantitative information about the sample structure through laser-driven PIXE analysis. These results pave the way towards the development of a compact and multi-functional apparatus for the elemental analysis of materials based on a laser-driven particle source.
