MCNP Simulation on Primary Energy Spectrum Distribution in X-ray Fluorescence Analysis

In X-ray fluorescence analysis, incident excitation energy spectrum directly determines the characteristics fluorescent intensity. This paper simulates X-ray spectrum distribution induced by electrons on different targets with MCNP program, and the results reveal spectrum feature of the characteristic line and continuum line under different simulated conditions. The simulated energy spectrum data can facilitate data processing of X-ray fluorescence analysis.
