  • Supercurrent device for controlling mobile flux vortices
    Patent number: 3936677
    Abstract: In an elongated weak-link supercurrent transmission line, the propagation of mobile flux vortices can be either enhanced or impeded by control means comprising a normal metal segment which interrupts either superconductor in the direction of vortex propagation and a control current source connected to the line at a point in operative relation to the normal metal segment. The control means either enhances or impedes the propagation of a vortex depending on the direction of the control current relative to that of the supercurrent associated with the vortex. The control means may also include a portion of the line in which its width is varied in order to change the velocity of the vortices.
