GRNN算法多球中子谱仪解谱软件设计

Design of a Multi-sphere Neutron Spectrum Unfolding Software Based on GRNN Algorithm

为更加准确的求解中子辐照环境中的中子能谱,编写了基于GRNN算法的多球解谱程序,设计了基于MATLAB的图形用户界面,开发了通用性强、计算准确、人机交互性能好的解谱软件。模拟计算以及实验测试的结果表明,该解谱软件实现了设计的功能,并且解谱结果与标准能谱相似度很高。

In order to get neutron spectrum in neutron radiation fields more accurately,multi-sphere neutron spectrum unfolding program based on GRNN algorithm is designed.Graphical user interface(GUI)based on MATLAB is designed,and a widely used,accurate and human-friendly spectrum unfolding software is developed.The results of simulation and experiment indicate that the spectrum unfolding software’s functions are realized,and the spectrum unfolding results are very similar to reference neutron spectra.
