Resumo

In this paper, we investigated a system, is composed of a natural tungsten and bismuth cylindrical targets. The target has been optimized to produce the maximum of neutrons yield with a diameter of 20 cm and varying height from 10 to 80 cm. The target is bombarded with a high-intensity accelerator by a 0.1 to 3 GeV proton beam. The protons are assumed uniformly distributed across the beam of diameter 2 cm. In this work, we have used Monte Carlo method by using MCNP-6 code to simulate spallation neutron yield, neutron spectrum and distribution of the spallation neutrons coming out of the target in the target region. According to the results approving using several simulations for two targets tungsten and bismuth, the difference of spallation neutron yield increases by 8.92% using a bismuth target and for some beam energy 3 GeV.
