Abstract

The flux jump stability characteristics of an edge-cooled tape superconductor are analysed. Two simple cases (no stabilizer, perfect stabilizer) are considered to establish the lower and upper bounds of the stable operating space. The generalized case is then solved in the interesting limit where the tape thickness is small compared with its width and compared with the one-dimensional condition of Hart. The two-dimensional analysis indicates that finite thermal diffusion in the superconductor can play a significant role for wo/d < 100, where wo is the half-width of the tape and d is the thickness of the superconductor.
