摘要：

TTSPM is a new computer program system for quantitative thick target analysis by nuclear microprobe based on PIXE analysis. It is multifunctional and most adaptable for different incident projectiles and various matrices while every process of production and detection of PIXE signals is considered including matrix attenuation and secondary fluorescence enhancement. This paper describes the principles of quantitative micro-PIXE analysis and the computer calculation methods, demonstrates the structure and the functions of TTSPM system, shows several results of standards comparisons and applications of the system in geology, material and other fields. Some new methods for resolving the overlapping peaks in PIXE spectra and eliminating the artifacts in 2D elemental maps are presented.
