Abstract
A method and system for quench detection in high temperature superconductors, such as REBCO (rare-earth barium copper oxide), before thermal runaway. A REBCO superconducting tape is excited as a transmission line forming standing waves. A quench may then be detected in response to detecting a disturbance of the standing waves. In this manner, quench in high temperature superconductors, such as REBCO, is rapidly detected before thermal runaway.
Claims28
A method for quench detection in superconductors, the method comprising:
- exciting a REBCO (rare-earth barium copper oxide) superconducting tape as a transmission line forming standing waves;
- and
- detecting a quench in response to detecting a disturbance of said standing waves.
A system for quench detection in superconductors, the system comprising:
- a REBCO (rare-earth barium copper oxide) superconducting tape architecture, comprising:
- a substrate;
- a buffer layer stack residing on said substrate, wherein said buffer layer stack comprises one or more dielectric layers;
- and
- a first REBCO layer above said buffer layer stack, wherein said first REBCO layer is used for transporting current to form a transmission line with said substrate;
- and
- a first device for exciting said REBCO superconducting tape architecture to form standing waves in said transmission line;
- and
- said first device or a second device for detecting a quench in response to detecting a disturbance of said standing waves.
