Executive Summary
This 1967 NASA contractor report, prepared by AVCO Corporation researchers Richard H. Levy and Francis W. French, explores the concept of a Plasma Radiation Shield designed to protect astronauts from solar flare-produced protons. The study concludes that using electromagnetic fields and free electrons for active shielding is theoretically sound, though it identifies significant practical challenges regarding high-voltage control and spacecraft integration.
