Abstract
A high temperature superconductor lead assembly for reducing the heat leak into a cryocooled system features a shroud configured for at least partial submersion in a cryogenic fluid contained within a bath chamber, and a high temperature superconductor lead element at least partially contained within the shroud. In use, a portion of the high temperature superconductor lead element contained within the shroud extends below a fluid level of the cryogenic fluid in the bath chamber. The portion of the high temperature superconductor lead element is thermally shielded by the shroud such that it is maintained at a temperature higher than the temperature of the cryogenic fluid. The shroud is a double-walled vacuum structure with a sealed end and an open end. In use, the open end is submerged in the cryogenic fluid.
