Abstract
Bombardment with beams of heavy molecular ions (cluster ions) has shown initial promise in a wide range of applications. Since little intuition has been developed about how the results are affected by the relevant experimental variables, e.g., cluster type, mass, and energy, these attempts at establishing feasibility may be quite far from being optimal in the choices of these parameters. I propose here that simulations based on molecular dynamics techniques may play a very important role in the efficient design and accurate interpretation of the next generation of such experiments. In addition to the impact this will have on applications in materials science, these calculations and the relevant experiments that follow may be important in determining the lifetimes of small grains in the interstellar medium.

The author is grateful to his collaborators, Jon Pelletier and Mark Shapiro, for access to their recent pioneering work in this field. Without their dedication to the elimination of spurious computational errors and to the improvement of computing efficiency, calculations of this sort could never have been performed. I also am most favored to have been chosen as a participant in this dual birthday celebration. Not only have I been a collaborator for many years with members of Bethge's ion beam applications group, but at an earlier stage of my career that involved accelerator design I was also much influenced by Klein's outstanding work on helical linacs. It is, therefore, a double pleasure for me to be a contributor to this symposium. One can certainly see in the programs of these men the very ingredients we shall need to make further progress in the field I have described.Additional details
