Abstract

The European Pathfinder project Unicorn aims to develop advanced nanoparticle-based scintillating materials for high-resolution and rapid-response radiation detection. This work explores the scintillation properties of nanocrystals in polymer matrices, aiming at applications in gamma and beta decay detection. The production of such scintillating composite requires to estimate the effect of absorption and scattering processes in the light transport on the performance of the final detector system. This contribution explores a novel experimental method using a spectrophotometer with a plug-in integrating sphere to obtain these parameters and investigates their influence on the light collection via Monte Carlo simulations in Geant4.

纳米复合闪烁体中光收集的模拟框架和实验方法的发展

欧洲的“独角兽”探路者项目旨在开发先进的基于纳米粒子的闪烁材料，用于高分辨率和快速响应的辐射检测。本研究探索了聚合物基体中纳米晶体的闪烁特性，旨在应用于伽马和β衰变检测。这种闪烁复合材料的生产需要估计光传输中的吸收和散射过程对最终探测器系统性能的影响。本文探索了一种新的实验方法，使用带有插件积分球的分光光度计来获得这些参数，并通过在Geant4中进行蒙特卡罗模拟来研究它们对光收集的影响。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
