Practical design considerations for HTS magnets require detailed magnetothermal analysis. Here we report investigations of the stability of high-T c superconducting tapes. As a result of the broad range of temperatures during a transition and the strong temperature dependence and anisotropy of the material properties, the finite element method (FEM) is used to solve the three-dimensional heat conduction equation. The heat source is determined using the operating current, the resistivity of the Ag and the critical current density of Bi2Sr2Ca2Cu3Ox (BSCCO). The minimum quench energy is determined for infinitely long uniform sources in the BSCCO.
