✦ Synopsis

In order to quantify stability in superconductors, the power supplied as external heat to drive the superconductor normal was measured. A t constant current and temperature, it was found that the conductor could not be driven normal below a certain critical field, and likewise at constant field there was a threshold critical current I t. The threshold current density Jt was found to correspond to the critical current density for the recovery of superconductivity after a disturbance, Jr.

The concept of face-cooled composite tape has been proposed to stabilize possible high critical current densities in high T c oxides. Stability is promoted by the combined action of dynamic stability and transient cryogenic stability. The expression for the limiting current density of stability is d
