Abstract

To solve the problem of lacking sensitive elements in the neutron energy spectrum measuring device caused by the shortage of

He gas and the increasingly expensive price

a set of BF

proportional counter multisphere spectrometer system is developed. Based on the Monte Carlo method

the detailed structure of the multisphere spectrometer system is modeled

and the energy sensitivity of the detector is obtained through simulation calculation. The energy response sensitivity of the spectrometer system is calibrated using 2.86 MeV and 14.84 MeV energy neutrons on the Cockcroft-Walton accelerator in China Institute of Atomic Energy

and the energy re

sponse sensitivity of the spectrometer system under experimental conditions is determined with the simulation results. Using this spectrometer system

the energy spectrum of the

Am-Be neutron source is measured

and the measurement results are deconvoluted using the self-edited Gravel algorithm. Comparison of
