Abstract The SRIM (formerly TRIM) Monte Carlo simulation code is widely used to compute a
number of parameters relevant to ion beam implantation and ion beam processing of
materials. It also has the capability to compute a common radiation damage exposure unit
known as atomic displacements per atom (dpa). Since dpa is a standard measure of primary
radiation damage production, most researchers who employ ion beams as a tool for
inducing radiation damage in materials use SRIM to determine the dpa associated with their …
