CHARACTERIZATION AND COMPARSION OF NEUTRON GENERATORS OF IEC AND LINEAR D-T BY THE SPECTROMETRIC SYSTEM NGA-01

This article focuses on description of two different neutron fields from linear and cylindrical Inertial Electrostatic Confinement (IEC) generators. Both these generators are well defined commonly used. They use a deuterium-tritium reaction that produces neutrons with energies in the range 13 – 16 MeV, depending direction energy incoming deuterium nucleus. Two-parametric spectrometric system for neutron/gamma mixed NGA-01 was used to characterize spectra proximity The 45x45 mm stilbene scintillator connected this device using an active voltage divider. way, we were able measure 1 - 15 MeV while filtering out gamma radiation, even when counts per second is high. For spectrum calculation recoil deconvolution through maximum likelihood estimation Measured have been compared simulations realized via MCNP6. According theoretical prediction, types produce fields. In case generator target very close point located tritium bombarded by deuterons. Thus varies angle between detector axis generator. experimental results simulation show shift peak pulse height histogram. IEC type more complicated. shape position depend heavily detector. most prominent effect plane perpendicular axis. case, splits into peaks can be measured distinguished. These verified diamond which also characterization
