Title: Strategies to enhance performance of superconductors for high-field applications

Abstract: 

In the pursuit of expanding the frontiers of high-field applications, from fusion energy to accelerator technology and beyond, the enhancement of superconducting magnets becomes paramount. The critical current carrying capacity lies at the core of enabling high-field superconducting magnets. This seminar offers a comprehensive exploration of a diverse spectrum of flux pinning techniques and pivotal advancements in fabrication processes, all directed towards the augmentation of the critical current properties in superconducting materials.
Our focus extends to emerging superconducting materials, notably MgB2 and Rare-earth Barium Cuprates (REBCO), showcasing their potential in revolutionizing high-field applications. We will also establish vital connections between superconducting performance and microstructural attributes, employing advanced characterization methods to deepen our understanding.
Join us in this enlightening seminar as we unravel the intricacies of superconducting enhancements, breaking barriers and opening new horizons for high-field applications.
