Nb$_3$Sn magnet conductors will continue to be the workhorse material for accelerator magnets over the coming decade because they can deliver significantly higher magnetic fields than Nb-Ti at significantly lower cost than higher performance HTS conductors. While R&D enhancements for advanced Nb$_3$Sn could improve performance by 30% or more in the 15-16 T field range envisioned for future...
The record Jc of commercial Nb3Sn conductors has been at a plateau since the early 2000s; however, much higher Jc than the state of the art is required for building the high-field accelerator magnets in future energy-frontier circular colliders. In the past few years a new type of Nb3Sn conductor with artificial pinning centers (APC) based on the internal oxidation method has demonstrated...
Recent years have seen significant development of superconducting Bi-2212 wires and magnets in the US with record critical current density, record wire lengths and record performance model magnets. For accelerator magnets, Rutherford cables have been used to construct racetrack coils, common coil dipole, and a canted cosine theta dipole magnet with structural management ability and good field...
