Ultra small angle neutron scattering from superconducting filament structures

摘要

With a perfect crystal camera, ultra small-angle scattering measurements were performed to investigate the internal diffu- sion process of tin inside a superconducting multi-filament wire caused by a temperature treatment. Commercially avail- able Nb_3Sn superconducting multi-filament wires were treated at 700 deg. C with varying ageing times up to 144h.
