Abstract

As the properties of high-temperature superconducting tapes improve, practical design considerations require more detailed analysis to prevent quenching. An important issue for high-temperature superconductors is stability: i.e. the ability to maintain or recover superconductivity in the event of a thermal disturbance or flux jump. As a result of the broad range of temperature 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 minimum quench energy for several sources is determined. The different cases considered include: convective boundary condition, source in BSCCO or Ag, increased anisotropy of thermal conductivity of bSCCO, increased critical current density and a constant source in Ag.
