A Simulation of Neutron Scattering via Geant4
Keywords:
simulation, neutron scattering, collimator, material, Geant4Abstract
Geant4 is a program developed by The European Organization for Particle Physics (CERN). This research applied Geant4 in a simulation of neutron scattering in a collimator, and subsequently for the modification of a collimator design for use with a nuclear research reactor. Six different materials were used in the simulation: concrete, iron, lead, bismuth, graphite and boron carbide. Trajectories of neutron particles produced during the reaction could be visualized through the simulation. The effects of the six materials on the kinetic energy of neutrons and the neutron scattering angle were studied. The results showed that iron was the most suitable material for fabrication of the collimator pile for a neutron reactor source with an energy level at 0.025 eV, due to its good neutron-reflecting ability. Boron carbide was not suitable, owing to its ability to absorb neutron particles.
