High temperature superconductors for commercial magnets

Arno Godeke

Abstract: The steadily increasing magnetic fields that can be generated with superconducting magnets are reaching the limits of what is achievable with low-temperature superconductors (LTS). At the same time, a reduction of fossil-fuel extraction will amplify the already limited availability of helium as a coolant for superconducting magnets in the near future. Hence, manufacturers of commercial applications that rely on superconducting magnets have become increasingly interested in exploring technologies that enable a m… Show more

“…For instance, high-temperature superconducting (HTS) materials typically have n-values around 20, whereas their low-temperature superconducting (LTS) counterparts boast values closer to 100. While HTS offers enhanced magnet protection, operating it near the critical current threshold-around 90%-can lead to resistive voltages, resulting in energy losses and potentially harmful heating effects [10,11].…”

“…However, most mechanical homogenization models ignored the fine structure of the HTS tape and cannot accurately calculate the stress-strain inside it, especially in the superconducting layer. In practical operation, the mechanical loads in HTS magnets cause complicated stress state inside the HTS tape such as tensile, bending, torsional stress, etc [28]. Therefore, it is necessary to develop a new modeling scheme to accurately calculate the stress-strain distribution inside the HTS tape during the operation of HTS magnets.…”
