Abstract
A one-dimensional heat conduction model is employed to predict burnout of a Bi2Sr2CaCu2O8 current lead, The upper end of the lead is assumed to be at 77 K and the lower end is at 4 K. The results show that burn out always occurs at the warmer end of the lead. The lead reaches its temperature in two distinct stages. the temperature rises slowly when part of the lead is in flux-flow As the local state. As the local temp erapure, it begins to increase shaply. Burnout time depends strongly o n flux-flow resistivity.
