Volume : I, Issue : XI, December - 2011 MULTILAYER RADIATION SHIELD FOR SATELLITE ELECTRONIC COMPONENTS PROTECTION Godwin Jacob D' Souza Published By : Laxmi Book Publication Abstract : This study presents the development, optimization, and analysis of multi-layer shields tailored for protection against electron and proton space environments. Using the MCNPX code and Genetic Optimization Algorithm, various shield designs are explored, focusing on materials suitable for safeguarding sensitive electronic devices. Through optimization, it's found that the total ionizing dose exceeds that of an aluminum shield by 53.3% for protons and 72% for electrons. Recognizing the significance of proton exposure in Low Earth Orbit (LEO), shield construction prioritizes proton shielding. An exemplary shield is constructed using a combination of Aluminum Bronze and molybdenum layers, supported by a copper carrier. Keywords : Article : Cite This Article : Godwin Jacob D' Souza, (2011).
