Abstract: Purpose of Presentation:• The "stopping power" is a critical ingredient in assessing material damage -but one has to understand the context in which it is used.In particular, one must understand the application.This, then, implies a need for details on the: a) application; b) source term, e.g., the ion type and its energy; c) damage metric of concern.• This presentation defines some terminology and establishes an application-focused framework for understanding the nuclear data needs in this area.• We must consider the uncertainties in the overall application of interest before we try to prioritize future activities (modeling and experimental) that address our nuclear data needs.2Why this is important?It helps provide a cost/benefit basis for setting our priorities for better modeling and for gathering more experimental data.While stopping power refers to the energy lost, the linear energy transfer (LET) refers to the energy absorbed.The unrestricted LET is the electronic stopping power. How Ions Interact with Matter 30There is a complex structure -in defect generation and in charge release.
