METHOD FOR QUENCH DETECTION USING RF INTERROGATION OF COOLANT PERMITTIVITY

Abstract: the present disclosure presents systems and methods for detecting a quench event in a superconductor. one such system comprises a cable extending down a metal tubular conduit and being cooled by a dielectric liquid near boiling point conditions to form a cable-conduit system; and a vector network analyzer that is configured to inject a stimulus signal and detect a local hot spot formation on the cable via a change in relative permittivity of the cable-conduit system.
