用于X射线荧光研究的基于Laser的X射线和电子源

Laser-based X-ray and electron source for X-ray fluorescence studies

F. Valle Brozas, A. Crego, L. Roso, A. Peralta Conde

摘要:

在这项工作中,我们提出了一种改进的传统的X射线荧光使用电子作为激发源,并比较它与传统的X射线激发的研究颜料。为此,我们已经构建了一个基于激光的源,能够产生X射线以及电子。由于X射线的穿透深度很大,所收集的荧光信号是所研究的艺术品的几个材料层的组合。然而,电子在第一层中停止,因此允许更肤浅的分析。我们表明,这两种激发源的组合可以提供非常有价值的信息的艺术品的结构。

英文摘要:

In this work we present a modification to conventional X-rays fluorescence using electrons as excitation source, and compare it with the traditional X-ray excitation for the study of pigments. For this purpose we have constructed a laser-based source capable to produce X-rays as well as electrons. Because of the large penetration depth of X-rays, the collected fluorescence signal is a combination of several material layers of the artwork under study. However electrons are stopped in the first layers allowing therefore a more superficial analysis. We show that the combination of both excitation sources can provide extremely valuable information about the structure of the artwork.
