Method for Protecting Satellites from Solar Energetic Particles Using Chaotic Magnetic Fields

Abstract
Satellites on orbit degrade in capability due to radiation exposure, from both the solar wind and solar flares. The goal here is to apply chaotic magnetic fields to protecting satellite circuitry from high energy particles in the space radiation environment as an alternative to prohibitively heavy and expensive radiation shielding for cubesats. We consider the use of chaotic magnetic fields both in redirecting high energy particles away from a satellite and in slowing high energy particles by increasing collisional processes. We demonstrate the existence of chaotic magnetic field lines (CMFLs) arising from simple combinations of individual current loops, using Lyapunov Exponents and the Higuchi Fractal Dimension to show chaotic behaviors of numerically integrated magnetic field lines. Finally, we discuss on orbit implications for using this type of system, including current requirements and volume limitations.
