ABSTRACT:
The film cryotron according to the invention comprises a superconducting ground plane with two superconducting electrodes arranged on said ground plane interconnected by an elongated distributed Josephson junction and provided with supply lines. The ground plane and electrodes are all insulated from one another. There are two holes in the ground plane opposite one of the electrodes, arranged so as to form a first screen at a portion in this electrode, shaped as a strip extending along the junction and adjacent thereto, as well as a second screened portion interposed between the holes and connecting the supply line to the middle of the first screened portion, and a third screened portion consisting of two halves which connect the ends of the first screened portion to the points of intersection of the electrode and a control line. At the points of connection to the first portion, the second and third portions have a width which is not in excess of that of the first portion. The cryotron includes at least one control line extending above the electrode opposite which the two holes are provided in the ground plane.
