High current power leads for Tokamak fusion reactor superconducting magnets
Abstract
A power lead system consisting of a superconducting section and a normal section is presented. By gas cooling both sections and holding the junction at 15 K with a separate refrigeration loop, it is shown that less refrigeration power is needed, as compared to a normal metal gas cooled lead. For optimum helium mass flow rates, the refrigeration power at room temperature for a composite lead can be about 20% less than for a normal metal lead.
