Abstract
Optimum copper to superconductor ratio (Cu/SC ratio) to maximize the superconductor composites stability is calculated for a given current and cross section of the composite using L. Dresner´s minimum quench energy formula. The optimum Cu/SC ratio was plotted as a function of the composite current density (20-420 A/mm2), while background magnetic fields varied from 4-8 T. It is shown that the optimum value decreases when the current density or background magnetic field increases
