Passive superconducting quench detection sensor
This paper discusses a passive superconducting sensor for detecting a quench in a superconducting coil having voltage taps. It comprises: a first circuit having electrically connected in series two voltage taps of the superconducting coil, a series resistive element R{sub p}, and a primary of a first transformer; a second circuit of superconducting elements having connected in series a secondary of the first transformer and a readout coil such that the second circuit is magnetically coupled to the first circuit by the first transformer, a readout device magnetically coupled to the readout coil for measuring a change in a current flow therein; and a second transformer having a superconducting secondary in series with the second circuit and being magnetically coupled to a primary winding in a loop circuit which detects flux changes in the superconducting coil.
