Abstract

REBCO high-temperature superconductors (HTS) provide a technical possibility for a high current density operation of a superconducting magnet. The intra-Layer No-insulation (LNI) method, one of the No-Insulation (NI) schemes, can be a promising solution for improving thermal stability and quench protection characteristics, which are vital to high current density operations. We previously proposed the concept of a resistance-controlled (RC) interface for controlling bypass resistance inside a coil winding and showed its electrical properties related to quench protection. In the present work, we measured the thermal conductive properties of an RC interface with a conduction cooling experiment on NI single pancake coils and numerically evaluated the characteristics of an LNI-REBCO coil implemented with the RC interface. The experimental and numerical results showed that the RC interface has high thermal conductive properties, which can be expected to contribute to the thermal stability of a coil under Joule heat dissipation as well as to cooling characteristics.
