新AGLAE外部光束线提供分析数据，用于了解考古和艺术品的结构，其组成，属性和随时间的变化。该项目的目标之一是设计和建立一个新的非侵入式采集系统，提高X射线光谱的质量，减少对敏感材料的束流。为此，PIXE探测器的表面和数量已经增加，以实现SDD探测器集群。这还可以提供利用射束在样本上的扫描来完成关于伪影的大的和/或快速的映射的可能性。在映射过程中，多参数系统保存来自X射线、伽马和粒子探测器的每个事件，同时保存样品上光束的X和Y位置。为了处理这些数据，开发或更新了不同的软件。第一个例子是一个装饰的中世纪碎片，突出了技术的角度。(C)2013爱思唯尔有限公司版权所有。
The New AGLAE external beamline provides analytical data for the understanding of the structure of archaeological and artistic objects, their composition, properties, and changes over time. One of the objectives of this project is to design and set up a new non-invasive acquisition system increasing the quality of the X-ray spectra and reducing the beam current on sensitive materials from work of art. To that end, the surface and the number of PIXE detectors have been increased to implement a cluster of SDD detectors. This can also provide the possibility to accomplish large and/or fast maps on artifacts with a scanning of the beam on the sample. During the mapping, a multi-parameter system saves each event from X-ray, gamma and particle detectors, simultaneously with the X and Y positions of the beam on the sample. To process the data, different softwares have been developed or updated. A first example on a decorated medieval shard highlights the perspectives of the technique. (C) 2013 Elsevier B.V.
