A new facility for High energy PIXE at the ARRONAX Facility
new facility High energy PIXE the ARRONAX Facility
2010/12/29
Proton Induced X-ray Emission (PIXE) using high energy protons is a non destructive multi elemental technique that can analyze medium and heavy trace elements on thick samples. A new experimental setu...
Particle induced X-ray emission (PIXE) is a physical effect that is not yet adequately modelled in Geant4. The current status as in Geant4 9.2 release is reviewed and new developments are described. T...
无标样厚靶PIXE分析中数值方法的应用
无标样 厚靶PIXE分析 数值方法
2009/7/27
本文用数值方法对厚靶PIXE分析中所测得的特征K-X射线强度进行修正.修正包括入射质子在靶中的慢化,特征X射线在厚样中的吸收以及基体元素的特征X射线引发的待测元素X射线的增强等.同时,为了进行元标样分析,同蒙特卡罗方法对整个分析系统作了效率刻度.在此基础上,对一些自制的标准厚样进行了PIXE实验分析,分析结果与已知值有较好的符合.
