Applications of HTS: Where do we stand and where can we go?
Over the last decades, superconductivity played a key role in expanding the frontiers of human knowledge. High field superconducting magnets have been the enabling technology for modern magnetic medical imaging, magnetic resonance spectroscopy, particle colliders and fusion reactors. To further expand our understanding of the world, these devices call for ever-increasing magnetic fields and thus the technological significance of high temperature superconductors (HTS), whose upper critical fields reach into tens or even hundreds of tesla, appears clear. However, since the discovery of HTS scientists had to face many challenges to develop these materials in a useful conductor form, and yet only three – Bi2Sr2CaCu2O8-x, Bi2Sr2Ca2Cu3O10-x and REBa2Cu3O7-x (RE = rare earth) – are available commercially. In this talk, I will address the current state and prospects of the HTS-based technology. The aim is to highlight how the development and property evolution in HTS conductors and the progresses in practical applications are going hand in hand with the quest for a deeper material understanding.
