For fusion reactor design, high-precision numerical simulations are required. However, there are still discrepancies among evaluated nuclear libraries. In this study, large angle elastic scattering cross sections of a fusion reactor structural material of tungsten at 14 MeV are tested with the previously proposed benchmark experimental arrangement by the authors’ group.
