Abstract: A supercurrent device includes a superconductor-normal metalsuperconductor (SNS) structure which has a current-voltage characteristic analogous to that of Josephson tunnel junctions but relies on a proximity effect rather than tunneling. Several devices employing the SNS structure are disclosed: a basic cryogenic switch or logic device, pulse generators and parametric devices.

Abstract: A supercurrent device includes a shunt conductance across an interfacial region having a finite zero voltage current characteristic of, but not limited to. Josephson tunnel junctions. The effect of the conductance is to raise the switchback current to convenient and controllable values and simultaneously to decrease the capacitive time constant associated with the device.
