Benchmarking of MCNPX with the experimental measurements of high-energy helium ions in HIMAC facility.
The main aim of this study is the qualfication of MCNPX code by using the experimental information obtained at HIMAC facility on the bombardment of different materials with He ions accelerated to 100 and 180 MeV/nucleon. The flux of secondary neutrons at different angles relative to ion direction is calculated and compared with published experimental data. Main findings are the reasonable modelling of the high-energy part of the secondary neutrons at forward angles and the code fail for the low-energy part.
