Abstract
A self-protected modular high temperature superconducting (HTS) down-lead that is capable of carrying large currents from a room temperature power source to a superconducting device operating at cryogenic temperatures. This down-lead incorporates a safety lead capable of carrying current and absorbing heat to protect the HTS material of the lead in the event of catastrophic failure of the HTS elements. The lead is in continuous contact with the HTS material and provides protection from interrupts and excess current. The down-lead is modular in design, and parts are easily replaced. Further, the down-lead is cooled through conduction in the middle stage, and gas cooled in the upper and lower stages by independent gas sources.
