Description
Summary:Scattering of energetic charged particles by high-voltage electrostatic tether structures may present a technically and economically viable method of rapidly remediating radiation belts caused by both natural processes and manmade events. In this paper, we describe a concept for a system of electrostatic tether structures designed to rapidly remediate an artificial radiation belt caused by a high altitude nuclear detonation. We then investigate the scaling of the system size and power requirements with the tether voltage and other design parameters. These scaling analyses indicate that a conventional single-line tether design cannot provide sufficient performance to achieve a system design that is viable. We then propose innovative multiwire tether geometry and show that this tether design can significantly improve the overall performance of the electrostatic system, enabling the requirements for total power and number of satellite systems to be reduced to levels that are both technically and economically viable
