In a no-insulation (NI) REBCO magnet, the turn-to-turn contact resistivity (ρc) determines its quench self-protection capability, charging delay time and the energy loss during field ramps. Therefore it is critically important to be able to control a range of ρc values suitable for various NI magnet coils. In this work, we investigate two possibilities to control ρc: by controlling the oxide layer of the copper surface of REBCO tapes; and by controlling the oxide layer in stainless steel co… 

Database of the effect of stabilizer on the resistivity and thermal conductivity of 20 different commercial REBCO tapes

The world’s first database on the effect of stabilizers on the resistivity and thermal conductivity of 20 different commercial REBa2Cu3O7−δ (REBCO) tapes was established. The resistivity and thermal

Design of a 20 T Class REBCO Insert in a 15 T Low Temperature Superconducting Magnet

A 20 T REBCO insert magnet has been designed considering a 15 T/150 mm background field generated by an LTS magnet. A two-nested-coil structure was chosen. The target of this project is to generate a

An electrometric method for the interface stress and contact resistance of pancake coil under winding force

Interface stress and contact resistance play key roles in the safety and stability assessment of non-insulated superconducting pancake coils. An electrometric method for the interfacial stresses and

Effect of the SS304 coating layer on the electrical and thermal properties of REBCO commercial tape

The effect of the 304 stainless steel (SS)-coated layer on the electrical and thermal properties in the radial direction of REBCO commercial tape was systematically investigated. The single SS-coated



Systematic Study of the Contact Resistance Between REBCO Tapes: Pressure Dependence in the Case of No-Insulation, Metal Co-Winding and Metal-Insulation

No-insulation and partial-insulation are novel approaches for compact, high field rare-earth-Ba2Cu3O7-x-coated conductor magnets. They maximize the current density and overcome some of the coated

26 T 35 mm all-GdBa2Cu3O7–x multi-width no-insulation superconducting magnet

A 26 T 35 mm winding diameter all-GdBa2Cu3O 7 − x (GdBCO) magnet was designed by the MIT Francis Bitter Magnet Laboratory, and constructed and tested by the SuNAM Co., Ltd. With the multi-width (MW)

Effect of Resistive Metal Cladding of HTS Tape on the Characteristic of No-Insulation Coil

This paper presents experimental and theoretical studies of the no-insulation (NI) winding method of second-generation high-temperature superconducting (HTS) wire. We compared two single pancake

Comparative study of the native oxide on 316L stainless steel by XPS and ToF-SIMS

The very thin native oxide film on stainless steel, of the order of 2 nm, is known to be readily modified by immersion in aqueous media. In this paper, X-ray photoelectron spectroscopy (XPS) and time

Critical Current Degradation of Coated Conductors Under Soldering Conditions

The critical current degradation of coated conductors was investigated at 77 K s.f., after heating the samples in a solder bath to temperatures between 200 °C and 300 °C for durations between 30 s

Metal-as-insulation variant of no-insulation HTS winding technique: pancake tests under high background magnetic field and high current at 4.2 K

In the framework of a project aiming at fabricating a 10 T high temperature superconducting (HTS) insert to operate in a 20 T background field, we are investigating the behavior of pancakes

A (RE)BCO Pancake Winding With Metal-as-Insulation

Against the more-proven NI technique, the results demonstrate that the MI technique, too, is quite viable for HTS pancake coils with the following features: nearly self-protecting; significantly smaller charging-delay time constant; and better control of coil parameters.
