Mechanically Reinforced MgB2 Wires and Tapes with High Transport Currents

TL;DR

This paper explores various reinforcement strategies for MgB2 wires to achieve high transport currents, emphasizing the influence of conductor design, precursor selection, and treatment processes on performance.

Contribution

It introduces new concepts for mechanically reinforced MgB2 wires and systematically characterizes their impact on critical transport currents.

Findings

Critical currents vary significantly with conductor concept

Precursor route choice affects superconducting performance

Treatment methods influence the achieved transport currents

Abstract

In this contribution, different concepts for mechanically reinforced MgB2 wires with high transport currents are presented and characterised. It is shown that the achieved critical transport currents depend strongly on the conductor concept, the choice of the precursor route and the applied treatment method.
