| Zusammenfassung: | Provided is a 14 MeV neutron thermalization device high in thermalization efficiency. A fast neutron reflecting layer is used for reflecting 14MeV neutrons which are emitted by a D-T neutron generator and are away from a thermal neutron collimation channel outlet, and the thermalization efficiency is improved by 185.10%. A fast neutron moderation layer and a neutron moderation layer are used for sequentially moderating the 14MeV neutrons, and the thermalization efficiency is improved by 36.81%. Polythene is used as a neutron moderation and thermalization material, the price of the polythene is far lower than heavy water, and the thermalization efficiency is 1.01% higher than that of water. The neutron reflecting layer is used for reflecting the neutrons away from the thermal neutron collimation channel outlet, and the thermalization efficiency is improved by 537.97%. A thermal neutron gathering layer is used for gathering and collimating the thermal neutrons in a collimation channel, and the thermalization ef |
