The Superconducting Technology Group at Bruker BioSpin, lead by Dr. Matteo Alessandrini, and the Group of Applied Superconductivity at University of Geneva have been recently awarded financial support by the Swiss Innovation Agency Innosuisse for a 3 years project. The title of the project is “HTS superconducting joints for NMR magnets”.
NMR spectrometers are used in biology, chemistry and pharmacy to study the structure, the interaction and the kinetics of complex molecules. The superconducting magnets in these systems must work in persistent current mode, i.e. the current cannot decay (drift) faster than a few parts-per-billion per hour. The goal of the project is to develop a reproducible technique for superconducting joints of REBCO coated conductors to pave the way towards research spectrometers with the highest possible resolution, thanks to the expanded magnetic field capabilities of high temperature superconductors.
