DEC-Shield technology offers the means to generate electric power from cosmic radiation sources and fuse dissimilar systems and functionality into a structural component to create a Multi-functional Structure (MFS). DEC-Shield integrated into MFS technology can be used to generate electric power and provide radiation protection in a space vehicle; even maximizing that protection by spreading the required systems and components across the structure. GTL will develop several DEC-Shield concept designs, fabricate test articles and test them in a representative radiation environment to demonstrate proof of concept. Further, GTL will analyze the test results and develop an optimized proof of concept DEC-Shield design. The Phase II effort will culminate with the design, fabrication and testing of DEC-Shield prototype Demonstration Panel that incorporates electrical power generation from GCR and solar wind sources.
