摘要: A mathematical model for an energy-dispersive X-ray spectrometer is proposed, which based on the analysis of radiation transport in a sample and detector, electron detector. The results obtained by using this are compared with experimental data. influence parameters sources primary X-rays, thickness material detector signal-to-background ratios, was estimated. These ratios limited photon were compared. It shown that ratio can vary several orders magnitude at changing conditions recording, there when use Si or Ge preferable.
