Abstract

A unique cryogenic system is needed to dump 106 to 107 litres of 1.8 K helium from a superconducting magnetic energy storage (SMES) unit in 5 to 20 seconds after the detection of an internal fault. The dump system includes quick-acting closures suitable for superfluid helium, refrigerated storage to receive and hold liquid helium without flashing losses, and a gas supply to maintain a positive pressure in the cryostat. The protection system transfers stored electromagnetic energy at low voltage into thermal energy absorbed by internal metallic axial structure. A rapid helium dump helps obtain more uniform final temperatures in the axial structure and conductor turns. Recommendations for specific hardware development are discussed.
