HZE BEAM TRANSPORT IN MULTILAYERED MATERIALS

A nonperturbative analytic solution of the high charge and energy (HZE ) Green's function is used to implement a computer code for laboratory ion beam transport in multiple-layered materials. The code is establi shed to operate on the Langley nuclear fragmentation model used in spa ce engineering applications. Computational procedures are established to generate linear energy transfer (LET) distributions for a specified ion beam and target for comparison with experimental measurement. Com parison with Fe-56 ion with Pb-Al and Pb-(CH2)(x) targets shows reason able agreement.
