Abstract

An epithermal neutron field using a Fixed Field Alternating Gradient (FFAG) accelerator has been studied by Kyushu University to develop epithermal neutron flux monitors. A spallation neutron source was utilized as the neutron generator. Tungsten was chosen as the target material. Iron, aluminum fluoride, and lead were selected for the moderator assembly material for high- and intermediate-energy neutrons and gamma rays, respectively. The Particle and Heavy Ion Transport code System (PHITS) was used to calculate the neutron flux on a water phantom surface and the RBE-weighted dose distributions in the phantom.
