Characteristics of an HTS Magnet Wound With 12-mm Zr-Doped HTS Tape

IEEE Transactions on Applied Superconductivity, 2014
This paper examined the properties of an high-temperature superconducting (HTS) magnet, such as the Ic-B relation and critical current, with pancake windings of a 12-mm-wide Zr-doped HTS tape. Considering the width of the Zr-doped HTS tape was 12 mm, which was three times wider than that of a conventional 4 mm tape, the current distribution at the ...

A Superconducting Cable With Curved HTS Tapes

IEEE Transactions on Applied Superconductivity, 2021
Critical current density is an important parameter reflecting power transmission capacity of HTS cable. Based on the superconducting energy pipeline, a tightly wound cable structure along arc of the pipeline is studied in this paper. Critical current density of electromagnetic thermal coupling is calculated and optimized superconducting cable structure

Finite-element recipes for HTS-coated conductors and HTS tape topologies

Superconductor Science and Technology, 2023
Abstract Different electromagnetic formulations were proposed and implemented in finite element (FE) software to model high-temperature superconductors-coated conductors (HTS-CCs) and HTS tape topologies. However, their modelling can be notably demanding in computational resources, particularly computation time.

Quench protection system for an HTS coil that uses Cu tape co-wound with an HTS tape

Superconductor Science and Technology, 2019
Abstract A quench protection system for a high-temperature superconducting (HTS) coil using Cu tape co-wound with an HTS tape was studied by numerical analysis using a thermal model of a coil winding pack. In normal operation, the voltage across the resistive zone V

Structural modeling of HTS tapes and cables

Cryogenics, 2016
Abstract Structural finite element analysis (FEA) has been used as an insightful tool to investigate the electromechanical behavior of HTS REBCO tapes and twisted stacked-tape cables under tension, torsion, bending and combined loads. A novel technique was developed for modeling the layered composite structure of the 2G tapes with structural solid ...

Magnetic Response of the Stacks of HTS Tapes

IEEE Transactions on Applied Superconductivity, 2016
We have performed a numerical analysis of the magnetic response of a single piece of a high-temperature superconducting (HTS) tape and the stacks of rectangular pieces of HTS tapes. The number of tapes in the stacks was varied from $N=1$ to 100. We have carried out the simulation in the framework of the critical state model, taking into account ...

A Superconducting Joint for 2G HTS Tapes

Technical Physics Letters, 2019
An approach of the epitaxial jointing of the GdBa2Cu3O7 – δ-based tapes using the YBa2Cu3O7 – δ layer is proposed. The structural and electrical characteristics of the formed joint have been investigated. Using the scanning transmission electron microscopy, the cross section of the joined region has been studied, partial melting of the YBa2Cu3O7 – δ ...
