Small additions of elemental Hafnium boosts current-carrying capability in Nb3Sn superconductor.
MagLab users have modified the critical current of Nb3SN, a material that was thought to be fully exploited, and boosted its performance by 50%.
The compact coil could lead to a new generation of magnets for biomedical research, nuclear fusion reactors and many applications in between.
With funding from the National Science Foundation, scientists and engineers will determine the best way to build a new class of record-breaking instruments.
Recent measurements of superconducting tapes in the MagLab's 45-tesla hybrid magnet shows that the power function dependence of current on magnetic field remains valid up to 45T in liquid helium, while for magnetic field in the plane of the tape conductor, almost no magnetic field dependence is observed. Thus design of ultra-high-field magnets capable of reaching 50T and higher is feasible using the latest high-critical current density REBCO tape.
Made with high-temperature superconductors, the National MagLab's newest instrument shatters a world record and opens new frontiers in science.
MagLab-industry partnership ups the critical current density of this high-temperature superconductor by a third.
