This superconducting coil design makes use of the magnetostatic radiation shielding strategy which operates by deflecting radioactive particles using a magnetic field. Superconducting coils are required to generate the magnetic field because of the very high currents involved. The advent of high-temperature superconductors has allowed the deployment of superconducting coils beyond the spacecraft hull. Outboard deployment of the superconducting coils permits much larger coils that result in huge power and mass savings compared to other inboard designs and the whole-habitat mass shielding protection strategy. However, to produce actual, practical shields, thin films with good flexibility and high critical current densities must be developed. These films may be produced by deposition of the superconducting material onto a flexible substrate. The substrate can then be affixed to the containment structure that could be produced from metallized Mylar. The substrate used in this study was gold foil. The superconducting medium consisted of an alcohol-based vehicle, a polymer binder, and YBa2Cu3O7-x superconducting powder.
