Description

This work presents a Monte Carlo code to get response spectrum of ions for the Neutron Depth Profiling (NDP) technique that simulates the behavior of ions transmitted through sample matrix and generates the energy spectrum for a specified detector. Based on the method of Monte Carlo simulation and probabilistic inversion for neutron depth profiling, the depth concentration distribution of element B in Si matrix material is calculated. According to NDP experimental equipment at CARR, energy spectra of standard sample SRM2137 are simulated using MCNP and Geant4 software, and the concentration-depth diagram of elements in SRM2137 is achieved adopting inverse iteration method through MATLAB software. It shows that the inverse iteration calculation in NDP is feasible.
