An accelerator-based neutron source using d-Li reactions is one of the most promising neutron sources for fusion material irradiation facilities such as IFMIF, DONES, and A-FNS. Yield estimation of neurons and other particles is very important in the design of those irradiation facilities. Currently, McDeLicious code is used for those yield estimations, however, it is not open code. Recently, a deuteron-induced reaction library of JENDL/DEU-2020 was released by JAEA. Benchmark tests of PHITS+JENDL/DEU-2020, MCNP+JENDL/DEU-2020, and McDeLicious have been carried out, where we confirm that PHITS (or MCNP)+JENDL/DEU-2020 reproduces well the experimental data and also the McDelicious results. We apply PHITS+JENDL/DEU-2020 to yield an estimation of neutrons, gammas, and charged particles in the Lithium target and also yield an estimation of charged particles in the target backplate for A-FNS. The production rates of tritium and 7Be during the continuous operation with a deuteron beam of 40 MeV and 125 mA are estimated to be 2.1 g and 0.21 g. Production rates of Helium and Hydrogen in the target backplate are estimated to be 3.2e2 ppm and 1.8e3 ppm, respectively. |
