Abstract
The Tai-Yang Research Company (TYRC) proposes to address the need for high temperature superconducting (HTS) current leads used in an adiabatic demagnetization refrigerator (ADR) for space applications, presently being developed at the NASA / Goddard Space Flight Center (GSFC). The innovation is to use a hybrid of two different HTS conductors bonded together at a thermally and electrically determined optimum point along the length of the current lead. The HTS conductor positioned at the warm end of the current lead will have a higher critical temperature (Tc) than the conductor at the cold end. This hybrid lead uses commercially available 2nd generation HTS conductors optimized for currents less than 10A. The warm end Tc is extended by using a bulk or thin film form not yet commercially available. TYRC will custom-fabricate the higher Tc materials and develop processes for joining them to the lower Tc material. TYRC will develop fabrication processes and generate options for mechanical design of the lead assembly.
