We have developed a classical trajectory Monte Carlo code for use in the 
study of collisions between highly charged ions and multiple target 
systems.  We have used this code to simulate a collision between a highly 
charged ion and a configuration of atoms initialized to mimic 
characteristics of LiF.  Each target atom has one electron localized 
about it. The forces between all particles are calculated at each step of 
the simulation and the trajectory of every particle is followed. Up to 
400 target  atoms are used in this work. Details of  the capture process, 
and the energy deposition to the surface are presented.
