| Research Abstract |
A superconducting magnet for the next generation muon experiments would be operated in a high radiation dose environment, thus the magnet materials should be chosen carefully considering its radiation hardness. In this study aluminum stabilizer and copper stabilizer used in the superconducting cable are irradiated by reactor neutrons, and the radiation effects in electric resistance are measured in-situ during exposure. The resistance of aluminum stabilizer is degraded at the same rate as in pure aluminum and the degradation rate of copper stabilizer is measured to be one third of aluminum.
