Summary

Experimental results show that the liquid helium occupying the void space within the winding has no beneficial effect against transient disturbances induced internally in the conductor; it does, however, slow down quench propagation. Because of the presence of an insulation layer at the conductor surface, the winding is effectively adiabatic against internal disturbance pulses. The trapped liquid helium is expected to be beneficial against transient heating applied external to the conductor surface, as would be the case with mechanical disturbances.
