Computer Modeling of Nuclear Interactions of Radiation Particles Upon Bulk Silicon Targets
Erich Schneider (University of Texas at Austin)

The Radiation Effects Group at the NASA Johnson Space Center (JSC) characterizes radiation damage to flight hardware using experimental and computational tools. We propose to support the activities of this group through the development and benchmarking of Monte Carlo radiation transport models for targets representative of this hardware. Specifically, we will characterize the interaction of radiation including energetic protons and heavy ions with silicon and other hardware materials. The computational models will be created in well-known, validated software packages such as MCNPX and FLUKA and they will be benchmarked against experimental data provided by JSC personnel. The benchmarked models will be of great utility for analyzing ioninduced radiation effects not directly reproducible from experiments, as well as for assessing many cases beyond those covered by the experiments. This work will be overseen by Principal Investigator Dr. Erich Schneider, Assistant Professor of Mechanical Engineering, Nuclear and Radiation Engineering Program at The University of Texas at Austin, with Dr. Sheldon Landsberger also of UT-Austin.
