Eretcad-Rad: The Multi-Method and Multi-Function Space Environment Radiation Effect Simulation Software

Abstract

In this paper, we describe the ERETCAD-Rad software, which is part of the Extreme-environment Radiation Effect Technology Computer Aided Design (ERETCAD) software. The aim of ERETCAD-Rad is for the simulations of the space environment radiation effects of materials, devices, and satellites. Depending on the simulation algorithms and the characteristics of the geometry structure, ERETCAD-Rad is divided into four modules, the Three-dimensional Monte Carlo (3DMC) module, the Reverse Monte Carlo (RMC) module, the One-dimensional Monte Carlo (1DMC) module and the sector shielding analysis (SSA) module. Multiple simulation methods such as Forward Monte Carlo (FMC), RMC and SSA, and multiple analysis functions such as total ionizing dose (TID), non-ionizing dose (NID), single particle effect (SEE), linear energy transfer (LET), non-ionizing energy loss (NIEL), energy deposition, fluence, equivalent dose, dose equivalent, internal charging are implemented in ERETCAD-Rad. Due to its functionality and flexibility, ERETCAD-Rad can satisfy the requirements of different users, for both the rapid engineering evaluations and the precise calculations of radiation effects.
