Supporting data for BNCT neutron spectrum measurement based on the thermal-neutron fluence-rate depth profile in a water phantom

It mainly includes activation measurement data of gold wire in water model body, single nucleus saturation reaction rate under bare gold wire and cadmium coated gold wire conditions, depth distribution data of thermal neutron flux obtained by cadmium difference method, depth response function of thermal neutron flux calculated by MCNP, and neutron energy spectrum expansion results obtained by MAXED and GRAVEL algorithms in UMG software.

The data also includes the comparison results of response functions under different beam divergence half angle conditions, the ratio of unfolded spectra to initial spectra, the relative deviation between calculated values and measured values, as well as the depth curve of active dry preheating neutron flux and the spectral results under different initial spectral conditions. This dataset can be used to reproduce experimental data processing, response function construction, neutron energy spectrum expansion results, and the main chart results in the paper.
