The neutron target station of the Compact Pulsed Hadron Source: A Monte Carlo simulation study

The neutron target station of the Compact Pulsed Hadron Source (CPHS) is tasked to generate neutrons through accelerating protons (13 MeV, 16 kW, 50 Hz, ∼0.5 ms pulse width) onto a beryllium target. The neutrons are slowed down through multiple scattering with the moderator and reflector media-solid methane and ambient temperature water, respectively, to eventually the thermal- and cold-neutron energies. In order to optimize the target-Moderator-Reflector (TMR) performance for CPHS, we carried out Monte-Carlo simulations of the neutronics regarding to neutron production and moderation. Here, we report the design concepts of the TMR assembly.
