摘要：NIPGA (Neutron Induced Prompt Gamma-ray Analysis) can analyze one sample of cement raw material in a few minutes. In order to improve the measurement accuracies of silicon, aluminum, iron and calcium, 50 samples were designed based on the data obtained from cement plants and simulated by MCNP. The relationship between the thermal neutron flux and elemental characteristic gamma-rays counts was found by linear regression analysis. When the counts and the flux calculated by the relationship are used to compute the element contents, all the accuracies can meet the demand of cement plants.
