Magnet technology and conductor design with high-temperature superconductors.

Summary

The implications of high-temperature superconductors for the design of magnets and conductors are explored. Presuming that a sufficient current density is attained in the superconductor, rules are given to obtain the amount of normal conductor and structural material. An empirical relation, linking effective current density and stored energy, naturally emerges from the requirements of sufficient mechanical strength as well as safe energy extraction in the case of a quench. In the superconductor a critical current density of 100,000 A/cm2 is sufficient for most purposes. As an alternative to cooling to 77 K in liquid nitrogen the authors also consider operation at 27 K in liquid neon.
