A Multi-Layer Green's Function Code for Ion Beam Transport

*† ‡ § A new version of the HZETRN code capable of simulating HZE ions with either laboratory or space boundary conditions is currently under development. The new code GRNTRN is based on recent improvements in the Green’s function approach to ion beam transport. Recent publications show that the new code accurately models the transport of ion beams through a single slab of material. Current research efforts are focused on enabling the code to handle multiple layers of material and the present paper reports on progress made towards that end.
