Abstract
The current study was carried out for neutron beam energies ranging between 14.8 and 19.2 MeV using the 3H(d,n)4He reaction and included neutron/gamma discrimination and neutron monitoring utilizing a BC501A liquid scintillator, followed by a pulse shape discrimination-capable circuit. Tests were conducted in order to determine the characteristics and limitations of the employed experimental setup. The deconvolution of the acquired spectra was performed using the DIFBAS computer code. The algorithm is based on the Bayesian conditional probability,whilethe covariance filter method was employed to calculate the a posteriori neutron flux spectrum along with its covariance matrix.The produced neutron beam proved to be practically monoenergetic for low energy deuterons, while at higher deuteron beam energies, the strong presence of parasitic and scattered neutrons was revealed.
