Abstract A computer program is described which treats the slowing down of ions in solids, and the associated formation of recoil atom cascades in the binary collision approximation. For multicomponent media, it takes into account dynamic alterations of the local composition which arise from the deposition of implanted ions and the collisional transport of target atoms. In this way, phenomena can be simulated which occur during high-fluence ion bombardment, such as implantation profiles, atomic mixing ... Title of program: TRIDYN (VERSION 3.1) Catalogue Id: ABFH_v1_0 Nature of problem A beam of fast ions (energy range app. 1 eV/amu to 100 KeV/amu) entering a solid substance is slowed down and scattered due to electronic interaction and nuclear collisions. Along its path, an individual projectile may create fast recoil atoms which in turn may initiate collision cascades of moving target atoms. These may either leave the surface (be sputtered) or be deposited at a site different from their original one. Together with the projectiles being deposited in the substance, this result ...
