Time evolution of ion slowing-down in amorphous solids

Time was introduced in the well-known TRIM code without changing the “event-driven” logic of the program. This modified TRIM code was used to simulate the slowing-down process of fast Cu ions in amorphous Cu targets. Distributions of the radial range and slowing-down time of the ions together with other time-dependent characteristics of the process were obtained at different projectile energies. A comparison was made with the results obtained by Robinson using the time-dependent MAR-LOWE computer code [Phys. Rev. B 40 (1989) 10717].
