Abstract

This paper describes the design, realization, and testing of a high-temperature superconducting (HTS) transmission line structure for delivering calibrated dc and ac signals to a cryogenic test platform. The inclusion of the HTS transmission line in the signal path reduces parasitic wiring resistance, maintains thermal isolation within the cryostat, and transmits dc through audio frequency signals with minimal loss and degradation.
