论文摘要
环境科学的主要挑战之一是土壤中污染痕迹（例如，镉或锑）的鉴定和化学演化，这需要长时间的收集时间才能在同步基金设施上进行准确的测量。在这种情况下，使用AllPix Squared框架研究了新一代多元素侦探在合理时间内以0.1-1 ppm识别痕迹的潜力。该代码已被自定义，包括由Comsol多物理学软件生成的三维电力和加权场图，以及对Soleil Synchrotron的样品环境进行建模的几个功能以及配备数字脉冲处理器（DPP）的也配备了也配备了数字脉冲处理器的锗检测器的信号响应。完整的模拟链已通过Soleil同步子的Samba光束线的实验数据验证。这项工作首先估算了使用此模拟链的未来多元素锗检测器对土壤样品中镉痕迹的检测极限。
One of the main challenges in Environmental sciences is the identification and chemical evolution of polluting traces (e.g, cadmium or antimony) in soil, which requires long acquistion times for accurate measurements at synchrotron facilities. In this context, the potential of a new generation multi-element germanium detectors to identify traces at 0.1-1~ppm in a reasonable time has been studied using Allpix Squared framework. This code has been customized to include the three dimensional electric and weighting field maps generated by COMSOL Multiphysics software, and several features to model the sample environment at SOLEIL synchrotron and the signal response of a germanium detector equipped with a Digital Pulse Processor (DPP). The full simulation chain has been validated by experimental data from SAMBA beamline of SOLEIL synchrotron. This work presents a first estimation of the detection limit to cadmium traces in a soil sample for a future multi-element germanium detector, using this simulation chain.
