We have studied chemical sputtering, hydrogen retention and other products of particle‐surface interactions in the least known, intermediate‐to‐low range of impact energies (1–30 eV/D), with atomic and molecular projectiles of deuterated amorphous carbon surfaces. Results from atomistic, molecular dynamics (MD) modeling using massive computation have been benchmarked against “in house” particle beam experiments, enhancing its predictive capabilities. We have extended previous MD simulations for well defined ion beam experiments to plasma‐bombardment environments using predefined distributions of impact particles in energy, angle, and angular momentum. Initial comparison with available plasma‐irradiation experimental data is encouraging. The quality of the existing interatomic potentials and research opportunities in the development of new potentials for mixed fusion materials are discussed.
