Embodiment Construction

[0030] Aspects of the invention have been shown to provide advantages over previous methods of cooling superconducting magnets. The apparatus and method of the present invention require no mechanically moving parts (e.g., no pumps, no supply system for external pressure, no refrigerated "cold box" for cryogen supply, no tank supply flow for helium, etc.). The cooling method is orientation independent which benefits the design, final physical volume and footprint of the superconducting magnet assembly. Design integration of piping within existing superconducting magnet geometries is simplified. Furthermore, any hot spots that may arise are immediately corrected by the pulsating slug flow provided by the pulsating heat pipes employed in aspects of the present invention. Additional advantages provided by the design are that no expensive helium bath cooling is required and no cryogen is lost during the quench. The proposed capillary tubing can withstand high pressures of severa...
