DREA-Developed Approach to Computer Simulation of ESD (Electrostatic Charging/Discharging) in Space Systems

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 charging/discharging (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.
