More Information
Summary:The contribution, to spacecraft avionics single event effect (SEE), nuclear reaction (NR), and total ionizing dose (TID) environments, of space radiation induced nuclear reactions and secondary particle showers in spacecraft materials is explored using the FLUKA Monte Carlo energetic particle transport code. Estimates of spacecraft single event upset rates produced using FLUKA based methods are compared to flight data. The elemental composition of avionics devices is shown to affect device SEE, NR, and TID environments as does the composition of the spacecraft structural shielding mass.
