Abstract

The stability of superconducting wires was studied by considering temperature and magnetic field. We measured critical current density of $Nb_3Sn$ tape at 4.2 K, 12 K, 13 K and 14 K in various field. The critical current density at 4.2 K, 6 T is 16.5 times higher than at 12 K, 6 T. We expressed the critical current density as a function of temperature and magnetic field, expanding on work by Hampshire, et al.
