“…The comparison result is shown in figure 10. The differences in the compared pulse-height distributions can be explained by the inaccurate accounting of the neutron scattering processes and by the neglecting of the charge collection processes in the Geant4 model (as in the similar works [11,16,17]). The pulse-height scale and the energy resolution evaluated from the experiment with the DT-neutrons did not correspond to the same characteristics evaluated from experiment with the alpha-particles.…”

The results of testing and characterisation of the neutron spectrometer based on a diamond detector are presented. It is shown that spectrometer calibration with monoenergetic electrons and alpha-particles leads to different results. The energy resolution of the spectrometer is estimated based on the experiments with alpha-particles and with DT-neutrons from NG-150M neutron generator. It has been shown experimentally that for neutrons with an energy of 14 MeV the energy resolution of a diamond-based spectrometer is 0.6%.

“…For such a distribution, the dependence of the right edge position on the neutron energy is non-linear. For its accurate determination, the modelling of the pulse-height distribution from diamond detector was performed using the Geant4 toolkit [14][15][16][17].…”
