Abstract
A Josephson junction comprises a cylindrical substrate having a flat end face disposed in a plane perpendicular to the axis of the cylinder. At least two bodies of superconducting material such as niobium, tantalum or vanadium are carried by the substrate and have boundary surfaces disposed in that plane. Insulating material and semiconductor material spaces apart the superconductors; and electrical supply means extend lengthwise of the cylinder to bring electric current to that plane. In one embodiment, the superconductors are disposed on opposite sides of the plane; while in another embodiment, they are all disposed on the same side of the plane.
