High field superconductor magnets greater than 10 T made from brittle Nb3Sn superconducting wires need special attention to their assembly, strength and endurance. This new study of damage in Nb3Sn superconducting wire from prototype accelerator coils built at CERN provides a path to designing better superconductor cables for the next generation of higher field accelerator magnets.
A recent test coil with more than 1300 meters of conductor successfully demonstrated a new winding technique for insulated REBCO technology and was fatigue cycled to high strain for hundreds of cycles. This is the MagLab's first "two-in-hand" wound coil and the first fatigue cycling test of a coil of this size, both of which are very important milestones on the path to a 40T user magnet.
Combining high-field NMR with infrared microscopy, scientists learned more about how gas diffuses in a novel class of molecular sieves that could one day be used for gas separation.
