“…Compared with experimental data, the energy distribution of the second peak is in good agreement with the simulation results. 15 There is a discrepancy of between experimental results and simulation data. The monoenergetic ions are only considered in this simulation whereas the other energy groups of ions can exist in the bulk plasma.…”

“…In order to address these shortcomings, a new type HNB source has been developed. 15,16 The key issue of HNB generation is understanding ionsurface interactions and neutral transport in plasma. With low energy ͑Յ100 eV͒ impact onto the metal surface, most ions are neutralized and scattered off, i.e., reflected, with little sputtering of surface atoms.…”

A hyperthermal neutral beam ͑HNB͒ source is one of candidate methods to reduce plasma-induced damage problems. The HNB is generated by vertical collisions between energetic ions and a reflector composed of a tungsten plate. We perform a HNB generation simulation using a molecular dynamics algorithm. The roughness of the reflector surface is experimentally measured and the surface structure is taken into consideration in the simulation. The energy and angular distributions of the HNB are obtained by the simulation and the energy yield of the reflected neutral particles is found to be in good agreement with experimental data.
