Abstract

The dynamic stability of an edge cooled superconducting tape is a non-linear, 3D magnetothermal problem. In this analysis, a two dimensional linearized version is solved using variational principles. To accurately model the physical behaviour of the conductor, trial functions are carefully chosen subject to the exact boundary conditions and a numerical solution is obtained. This solution is compared to a recently obtained analytic solution and the one dimensional solution obtained by Hart. The 2D analysis indicates that the finite thermal diffusion in the superconductor can play a significant role for wo/dsc< 100, where Wo is the half width of the tape and dscis the thickness of the superconductor.
