摘要： A method of operating a superconducting switch system to protect against quenching in a superconducting magnet circuit is provided. The system comprises a magnet circuit, a main superconducting switch and an auxiliary superconducting switch connected in parallel thereto by low resistance connecting parts. In an initial magnet energisation procedure, after establishing superconducting flow in the circuit, the main and auxiliary switches are closed to cause current to persist in the circuit without further power input. If the main switch quenches, the current will transfer to the auxiliary switch through the resistive connecting parts. Upon restoring the main switch to the superconducting state, the voltage drop through the resistive connecting parts will drive the current back through the main switch. A preconditioning procedure is carried out as part of the magnet energisation procedure to ensure that opening the main switch will establish superconducting current through the auxiliary switch.
