Abstract
Space radiation and its effects on human life and sensitive equipment are of concern to a safe exploration of space. Radiation fields are modified in quality and quantity by intervening shielding materials. The modification of space radiation by shielding materials is modeled by deterministic transport codes using the Boltzmann transport equation. Databases of cross sections for particle production are needed as input for transport codes. A simple model of nucleon-nucleon interactions is developed and used to derive differential and total cross sections. The validity of the model is verified for proton-proton elastic scattering and applied to delta-resonance production. Additionally, a comprehensive validation program of the nucleus-nucleus fragmentation cross section models NUCFRG2 and QMSFRG is performed. A database of over 300 experiments was assembled and used to compare to model fragmentation cross sections.
