Advances in large scale applications of superconductors

Most applications are still relying on LTS use as the magnet systems for large accelerators and for magnetic fusion devices. NMR spectrometers are approaching the 1000 MHz class (23.5 T in the magnet bore), a challenge to most advanced LTSs as well as to HTSs. In MRI trends for HTS use have successfully been demonstrated, as well as for cryogen-free magnets, SMES and magnetic separation. However economy will depend on HTS wire cost reductions. Already well in use are HTS current leads, contributing to advantages for magnets in many areas. (author)
