Analysis optimizes a superconducting magnet design to shield crewmembers from solar cosmic rays in interplanetary missions, suggesting efficient configurations.
During manned interplanetary missions, it is necessary to protect the crewmembers from the high energetic solar cosmic rays, mainly protons. A feasible solution consists of an active shield by means of a superconducting magnet. This magnetic lens is able to deflect the almost unidirectional solar cosmic rays away from the zone that can be occupied by crewmembers. Our study indicates that an air core toroid with inner diameter of 0.5 m and outer diameter of 3.5 m and a peak field of 2.80 T is suitable for astronaut protection. In this paper the detailed magnetic, mechanical and thermal design is presented, and different configurations for the superconducting coils are compared in order to find the most efficient and convenient solution in such a complex environment.
