在过去的十年中，使用负μ子束的非破坏性元素分析取得了显着进展。该方法可用于确定散装材料的元素组成，而不会造成损坏。在这项研究中，我们进行了负μ子照射实验的西北非洲482月球陨石（NWA482），这是安装在一个不锈钢分析室。分析室充满氦气，以抑制由空气散射μ子引起的背景信号。样品中来自Al、Fe、Ca、Mg、Si和O的μ子X射线使用布置在分析室周围的六个高纯度锗半导体探测器来检测。为了校正样品的X射线自吸收效应，使用使用Geant 4工具包的蒙特-卡罗模拟。在对μ子X射线测量进行定量分析的基础上，利用NWA482数据，成功地研究了陨石中各元素的分析灵敏度。
In the last decade, non-destructive elemental analysis using negative muon beams advanced significantly. This method can be used to determine the elemental composition of bulk materials without causing damage. In this study, we performed a negative muon irradiation experiment for a Northwest Africa 482 lunar meteorite (NWA482), which was installed in a stainless steel analysis chamber. The analysis chamber was filled with helium gas to suppress the background signals caused by air-scattering muons. The muonic X-rays from Al, Fe, Ca, Mg, Si, and O in the samples were detected using six high-purity germanium semiconductor detectors arranged around the analysis chamber. To correct the X-ray self-absorption effect of the samples, a Monte-Carlo simulation using Geant4 toolkit was used. Based on the quantitative analysis for muonic X-ray measurement with the correction application from the simulation, we successfully investigated the analytical sensitivity of each element in meteorites based on the NWA482 data.
