Abstract

The superconducting properties of Nb and Nb3Sn with nanometer-size copper artificial pinning centers (APC) are investigated. The non-scaling of the pinning force with temperature for APC enhanced Nb sample is observed. The non-scaling behavior is very similar to that of optimized NbTi conductor. Proximity effect occurs when the size of Nb filaments is smaller than twice the coherence length of Nb. The maximum pinning force of APC enhanced Nb3Sn samples shifts to higher reduced magnetic field.
