Analysis, Design and Optimization of the Multi Layer Radiation Shielding of Satellite Electronic Components

Abstract

In this paper, multi layer radiation shield is designed for electrons and protons space environments to protect in all satellite orbits. The designed shield layer material and thickness is analyzed and optimized by MCNPX linked with Matlab. In Matlab, genetic algorithm is employed for optimization where the cost function is obtained from MCNPX. The designed shield achieves more than 53% TID reduction for proton environment and more 72% TID reduction for electron environment compared with aluminum by similar thickness. This good specifications prove the capability and ability of the deigned multilayer shields to protect the electronic parts in the satellite applications.
