Description: The Tai-Yang Research Company (TYRC) of Tallahassee, Florida proposes to build hybrid high-temperature superconducting current leads for space applications, including compact adiabatic demagnetization refrigeration (ADR) systems for sensor cooling. The current leads will be configured to meet NASA mission requirements for a low heat leak in a package optimized for electrical currents up to 10 A. The novel, proprietary construction by TYRC consists of a tough, flexible cold end section and a high critical temperature warm end section.
