Heating-Induced Performance Degradation of REBa2Cu3O7–x Coated Conductors: An Oxygen Out-Diffusion Scenario with Two Activation Energies

ACS Appl. Electron. Mater. 2022, 4, 3, 1318–1326

The degradation of the superconducting properties of REBa2Cu3O7–x coated conductors when heated above 150 °C is a topic of concern for any...

Machine learning applied to X-ray tomography as a new tool to analyze the voids in RRP Nb3Sn wires

Scientific Reports, 11, 7767 (2021)

The electro-mechanical and electro-thermal properties of high-performance Restacked-Rod-Process (RRP) Nb3Sn wires are key factors in the realization of compact magnets above 15 T for the future...

Very high upper critical fields and enhanced critical current densities in Nb3Sn superconductors based on Nb–Ta–Zr alloys and internal oxidation

Journal of Physics: Materials, Volume 4, Number 2, 2021

The inhibition of Nb3Sn grain growth in the presence of ZrO2 nanoparticles appears to be one of the most promising method for pushing the critical current densities of Nb3Sn...

HTS Accelerator Magnet and Conductor Development in Europe

Instruments 2021, 5(1), 8

In view of the preparation for a post-LHC collider, in 2010 the high-energy physics (HEP) community started to discuss various options, including the use of HTS for very high-field dipoles. Therefore, a small ...

High-field superconductivity in C-doped MgB2 bulk samples prepared by a rapid synthesis route
