- Abstract
A new method for estimating fast neutron energy, based on in situ X-ray fluorescence analysis technology, has been proposed. According to the simulation results, the fluorescence mainly originates from the interactions of intermediate particles protons, electrons, and X/gamma-rays with target atoms. The contribution of fluorescence excited by each type of particle to the overall fluorescence intensity presents distinct characteristics as neutron energy varies. Finally, by analyzing the fluorescence intensity ratios of Ag, Mo, W to Bi as examples, a power function relationship between neutron energy and the fluorescence intensity ratio was derived, preliminary demonstrating the feasibility of the method.
