In this paper, we have examined the recovery of current leads for superconducting magnets after loss of coolant. It is found that if a lead is without cooling for longer than a time τ max, thermal runaway can be prevented by an increase in cooling or a decrease in current through the lead.It is evident that designing a lead away from its optimal values can make the lead significantly less ...
