    Theoretical magnetic field diagram for a superconducting disc floating over three BZ magnets Superconductors repel magnetic fields due to the Meissner effect. Near the surface of the superconductor material, small currents flow (without any resistance) that make an opposite magnetic field that repels the field from the magnet.

radiation-hard superconducting magnets. This work is a part of the R&D programs for radiation-hard superconducting magnets. A superconducting magnet consists of not only superconductor, but also stabilizer, insulator, glue, thermal conductor, thermosensor and other materials.

Each component should be reviewed in the development. NASA along with its partners is exploring the possibility of using superconducting magnets to generate magnetic fields around space probes and space habitats to protect them from space radiation and cosmic rays.

“The concept of shielding astronauts with magnetic fields has been studied for over 40 years, and it remains an intractable engineering problem,” says Shayne Westover of Johnson. The data base on radiation damage to Nb{sub 3}Sn superconductors is compiled from the literature and assessed in this report.

Nb{sub 3}Sn superconductors are currently under procurement for use in ITER magnet prototypes. In contrast to the data base on insulation materials proposed for use in ITER magnets, the data base on the radiation damage of Nb{sub 3}Sn is much more : N.J.
