SUPERCONDUCTING SWITCH FOR A SUPERCONDUCTING MAGNET

A superconducting magnet includes a cooling tank containing a cooling medium and at least one superconducting circuit configured for generating a magnetic field. The superconducting magnet further includes a power supply connected to the superconducting circuit(s) for energizing the superconducting circuit(s) and a superconducting switch electrically connected across ends of the superconducting circuit(s). The superconducting switch includes a superconducting winding and a thermal conduction member having a first end thermally coupled to the superconducting winding and a second end thermally coupled to the cooling medium within the cooling tank. The thermal conduction member includes, at least, a first layer and a second layer. The first layer is constructed of a metal material having a first thermal conductivity. The second layer supports the first layer and is constructed of a material having a second thermal conductivity that is lower than the first thermal conductivity.
