The stability of neutron generator yield can be solved by establishing accurate mathematical model for neutron tube.Based on the analysis and testing of the storage,ion source,accelerator voltage and accelerator current of the neutron tube,the neutron tube model is divided into a combination of beam extraction model and yield output model.The beam extraction model of neutron tube was established by using the multivariate polynomial regression fitting method in sk-learn library in python.It is found that the goodness-of-fit score of the two-level multivariate polynomial is 0.9879,which lays a foundation for the development of high stability neutron generator in the future.
