Abstract

Among various types of neutron generators, the spallation neutron source is a unique way to generate high-energy and high-flux neutrons in a laboratory. The advantages of the spallation neutron source over other types of generators have been recognized; as a result, several spallation neutron facilities are in operation to provide users with high-quality neutron beams. For satisfying the demand for such a neutron facility in Korea, we have launched a project to construct a spallation neutron source facility by fully utilizing the high-power proton linear accelerator at the Korea Multipurpose Accelerator Complex (KOMAC) of the Korea Atomic Energy Research Institute (KAERI). In the facility, high-energy spallation neutrons can be generated by bombarding a thick metal target with a 100-MeV, 20-mA pulsed proton beam. In the present study, a neutron target system involving a target, moderator, and reflector (TMR) has been studied through extensive Monte- Carlo simulations. The detailed design of the TMR for generating thermal neutrons and guiding them to the experimental hall will be presented. Here, we present the result of numerical studies and the details of fundamental instruments, and we discuss future plans for the construction of the spallation neutron source facility at the KOMAC.
