Abstract
An empirical model is presented that predicts the critical current density (J c) of Nb3Sn wires under the combined effects of temperature, strain, and radiation damage. The model, based on previous work of D.P. Hampshire et al. (1985) and J. W. Ekin (1980), predicts J c with a reasonable degree of accuracy. The model can be used with a limited number of input parameters. eliminating the need for detailed characterization, particularly the difficult tasks of measuring critical current as a function of temperature and radiation damage
