Abstract

Developing successful and optimal solutions to mitigating the bio-hazards of severe space radiation is critical for the success of deep-space explorations. A recent report has explored the feasibility of using a hybrid configuration that utilized both electrostatic and magnetostatic fields. Here we extend the analyses in an effort to optimize the hybrid configuration. These include changes in the radius of the current-carrying ring, and the use of multiple rings for greater bio-protection. Our simulation results show GCR proton transmission to be reduced down to 15 percent at energies around 1 GeV for a magnetic ring with a 70 meter radius. Use of three orthogonal rings is predicted to reduce the 1GeV GCR proton transmission to ~12 percent, even with smaller (35 meter radius) rings.
