Title: Terminating device for permanent current
Inventor: FUJIMAKI NORIO
IPC: H01L39/22
Filed: 1989-12-27
Abstract: PURPOSE:To terminate a permanent current of a superconducting loop without almost supplying a current by inserting a channel of a field-effect superconducting 3-terminal element to the loop, and connecting a voltage source for switching the channel to superconduction or normal conduction to the gate electrode of the element. CONSTITUTION:A superconducting loop 10 is made of a superconductor such as a superconducting inductor 14, a superconducting wire 12, etc., and a Josephson junction 16 is contained in the loop 10. A channel CH of a field-effect superconducting 3-terminal element 20 is inserted to the loop 10, and the gate voltage of the gate electrode is controlled by a voltage source Vs. That is, when the gate G of the element is OFF, the channel CH is in a superconducting state. When it is turned ON, the channel CH becomes a normal conducting state, and a permanent current becomes zero. Accordingly, it is voltage that varies to control the element 20, and almost no control current flow. Thus, the permanent current of the superconducting loop can be terminated with almost no current supply.
