Abstract
A combination refrigerator and current lead assembly includes a pulse tube having a cold end and a warm end. A first electrical connector is attached to the warm end. A second electrical connector attached to the pulse tube supplies current to a lead, for example, a high temperature superconductor lead. The assembly includes a second pulse tube having an electrical connector attached at its warm end and a second electrical connector for supplying current to a lead. The second electrical connectors are attached to the cold ends of the pulse tube. The pulse tubes are formed from an electrically conductive material. An electrical isolator electrically isolates the pulse tubes from each other. Additional electrical isolators electrically isolate the pulse tubes from a compressor, valve, and regenerators of the system.
