Mechanical strain effects in design considerations of high-critical temperature superconducting pancake coil magnets.

Summary

Bending of superconducting tapes to form coils results in degradation of the critical-current density. Theoretical computations show that even when the coil satisfies the critical-current density criterion of 1 microV/cm, a significant portion of the coil operates above the 1 microV/cm criterion and is compensated by the remaining coil which operates below the critical-current density criteria. The net degradation in the critical-current density is determined by the geometrical parameters of the coil and the tolerance of the critical-current density of the conductor to mechanical strains. The formulations and results described may be used as a guide for the design of pancake coil magnets.
