# Incorporating Electron Range Approximations into Secondary Electron Emission Models

Session 2

#### Description

Secondary Electron Yield is a key parameter in spacecraft charging. In order to develop a robust model to predict the secondary electron yield for any given material, the work done by Utah State University’s Materials Physics Group on electron range is extended to the yield problem. This newly developed yield model uses the probabilistic nature of inelastic collisions to incorporate the material dependent inelastic mean free path model used in USU’s MPG’s range model.
