摘要： Disclosed is the structure of a persistent current switch and a control method for the same. In the switch structure, a portion of a superconducting wire to be used as a switch is formed with slits such that the flow of current is controlled by the switch, to facilitate a transition between the superconducting state and the normal state of the superconducting wire. The structure of the persistent current switch includes a first slit longitudinally extending from a first point on one end of a superconducting wire to a second point and from a third point to a fourth point, the second, third, and fourth points being arranged sequentially in a longitudinal line, and second and third slits provided at opposite sides of a region between the second point and the third point where no first slit exists, the second and third slits having a length longer than a distance between the second point and the third point. As a result of providing the switch with the slits to facilitate a transition between the superconducting state and the normal state of the superconducting wire by controlling the flow of current through the superconducting wire, the superconducting wire can be easily changed from the superconducting state to the normal state even by slight heat. Accordingly, in an actual use thereof, the superconducting wire can reduce thermal load to be applied to a cooling system and assure easy regulation in the position of the switch.
