19 49,306 ABSTRACT OF THE DISCLOSURE An apparatus is provided for rapidly restarting the flow of coolant through the cold electromagnetic shield of a superconducting rotor following a thermal transient episode. A vortex diode inhibits coolant flow in the undesirable reverse direction and encourages the reestablishment of a normal thermosyphon cooling loop flow quickly following the termination of a thermal transient such as that caused by transmission line faults. The present invention requires no moving parts and may there- fore be permanently sealed in the superconducting rotor without risk of costly repair efforts caused by components failure.
