Abstract

This paper presents the design concept and key parameters of a pair of 1-kA AMI-MIT Leads, comprised of a high-temperature superconducting (HTS) section that, over a short distance at the warm end (80 K), operates in the current-sharing mode and a vapor-cooled copper lead that covers the temperature range above 80 K. Because of their reliance on vapor cooling, AMI-MIT Leads are applicable only to liquid helium cooled superconducting magnets such as those used in high-energy physics accelerators and fusion machines. The new 1-kA HTS section is designed to be scalable to high-current leads, e.g., 6 kA, 25 kA, 40 kA.
