    Abstract: Superconducting cables employ one or more superconducting tapes wound around a former. A compact superconducting cable is configured using a former having a small diameter, e.g., less than 10 millimeters. A flexible superconducting cable is configured with a former made of a flexible material. Superconducting tape conductors are wound around the former, with the superconducting layer in compression on the inside of the wind turns of the wind, to prevent irreversible damage to the superconductor. A layer of solder is on the superconducting tape(s) or solder sheaths are wound between tape conductors in each layer. The one or more solder layers or sheaths are melted to cause the solder to flow within the structure, to bond some or all of the superconducting tape conductors together and form a mechanically strong cable with an enhanced level of electrical connectivity between tapes in the cable.

A transient pulse generator applies a transient pulse to the element. The transient pulse changes the state of the element between the first (high) and second (low) states, the element being superconductive in the first (high) state, and the element being resistive in the second (low) state.

A process for the production of a YBa.sub.2 Cu.sub.3 O.sub.7-x or YBa.sub.2 Cu.sub.3 O.sub.7-x -Ag superconducting material which exhibits bifurcation in its critical current density versus temperature curve. The process involves the provision of the appropriate powder or mix of powders, pressing the powder to form the desired specimen, sintering the specimen at a sufficient temperature for a sufficient time to achieve fusion of the powder, heat treating the sintered specimen, and subjecting the specimen to an oxygenation process.
