  • Abstract
    The radiation hardness of a new technology using Josephson junctions was explored by an irradiation using a fluence of 7.6×10 14 protons/cm2 at an energy of 63 MeV from the U.C. Davis cyclotron. In what may be the first radiation assessment of Nb/Al2O3/Nb devices, the permanent damage in these devices was investigated. No permanent changes in the I-V characteristics of the junctions were observed, indicating no significant level of material defects have occurred at this level of irradiation
