Field, angular, and defect dependence of the critical current of Nb3Sn for t≤4.2°K

Measurements are reported for the critical current of chemically transported Nb3Sn as a function of applied field from 0 to 104 kG. The angular variation of the critical current at constant field is examined in detail. Data are given for the temperature dependence of the transverse and longitudinal critical current as well as the effect of neutron damage on homogeneous low-α specimens of Nb3Sn.
