A new reflector structure for facility thermalizing D-T neutrons
Original language description
A facility for thermalization of fast neutrons (14.2 MeV) emitted by compact deuterium-tritium (D-T) neutron generators (NGs) for thermal neutron activation analysis is proposed. Its final design is based on Monte Carlo calculations (MCNP5). To maximizethe ratio between the thermal neutron flux and the total neutron flux and simultaneously to ensure the highest possible value of the thermal neutron flux at the output surface, the facility should consist of a two-layer reflector [tungsten (W)-the innerpart, molybdenum-the outer part], a two-layer multiplier (W followed by lead), a moderator (polyethylene followed by magnesium fluoride) and a collimator (molybdenum and nickel near the output surface). For the D-T NG producing the maximum available neutron yield 10(15) n s(-1), the facility provides the thermal neutron flux 2.0 x 10(11) n cm(-2) s (-1) and a slightly higher fast neutron flux 2.3 x 10(11) n cm(-2) s(-1). To improve the ratio of the thermal neutron flux to the fast neutro
