Summary

Description

<p> This project aims to leverage near-term high-temperature superconducting technologies to assess applicability of magnetic shielding for protecting against exposure from Solar Proton Events (SPEs) and dose reduction for Galactic Cosmic Radiation (GCR) utilizing HTS magnet technology concepts. Shield design can have substantially lower mass/power requirements than previously thought. Modeling efforts will include: (1) Modeling of realistic magnetic fields (Halbach array) utilizing full-scale finite-element methods that include fringing fields; (2) leveraging of recent plasma trapping results (Rutherford/Appleton Laboratory); (3) and if time permits, a habitat model will be included as parasitic shielding. Testing will be conducted with a magnet array for plasma trapping facilitated at Ad Astra utilizing current Space Act Agreements. The study will evaluate shorter duration missions from a power, mass, flux reduction perspective and provide an active and passive shielding mass comparison.</p>
