KEK and NIMS have been jointly developing Nb3Al superconducting wire with a rapid heating and quenching (RHQ) method towards high field accelerator magnets in the Large Hadron Collider (LHC) luminosity upgrade. A15-type superconductors such as Nb3Al and Nb3Sn exhibit strain dependence with respect to their critical currents. Therefore, a thorough understanding of strain behavior is necessary for high field accelerator magnet development, which will be critical for the luminosity upgrade of the LHC.
