OSTI ID:5394230
This patent describes a controllable active superconducting device. It comprises a main conduction channel formed of a film of superconductor on a substrate; an active weak link region interposed sin the main conduction channel, the active weak link region composed of a plurality of links formed of a thin film of superconductor separated by non-superconductive voids, the thickness and lateral dimensions of the links selected such that magnetic flux can propagate across the weak link region when it is superconducting means for providing a magnetic flux to the active weak link region which can propagate across the weak link region to control the resistance of the weak region.
