Abstract:

Space radiation has deleterious effects on satellite electronic components and systems. To be able to predict the likely radiation scenario for a given orbit and space platform, DREO has developed a modeling tool that simulates radiation effects such as electrostatic chargingdischarging ESD and dose deposition into complex targets. The codes used by the model are described in considerable detail. The most important code is the Monte Carlo radiation transport code for electrons and gammas. Complex targets are assembled using combinatorial geometry approach utilizing the code called Builder, developed in-house. The results are displayed, also with in house developed code called Docker. Several examples of deep electrostatic charging ESD in dielectric materials, satellite and components are given. Manuals for the Docker and the ACCEPT codes are available upon request.
