| Popis: | Characteristics of a source of thermal neutrons based on an evacuated NG-400 neutron generator with the maximum flux (Φf) 2 × 1011 neutron/s for 14 MeV neutrons and 2 × 109 neutrons/s for 3 meV neutrons have been investigated. The possibilities of its application for neutron activation analysis have been estimated. The distribution, composition, and density (φT) values of the thermal neutron flux have been measured in the inner cavity of the moderator using activation detectors. φT was 2 × 108 and 2 × 106 neutrons/cm2 s for thermalized neutrons with energies of 14 and 3 MeV, respectively. The possibilities of the apparatus have been estimated theoretically and experimentally for the cases of thermalized neutrons of 14 MeV and 3 MeV. |
