Title: Development and Study of Nb3Sn Conductors with High Specific Heat

Abstract

Recently a new type of Nb3Sn conductors were developed, which, by incorporating substances with high specific heat at 2-8 K in a proper design, have demonstrated significant improvement of minimum quench energy (MQE). This approach to improving energy margins of conductors is promising to reduce Nb3Sn magnet training. In this work we continue studying this type of conductors. Voltage-current (V-I) measurements from 15 T to 0 T and voltage-field (V-B) sweeps at various currents were conducted to investigate the influence of increased specific heat on the intrinsic stability of Nb3Sn conductors. Normal zone propagation velocity (NZPV) was also studied. Finally, a new scheme was put forward to introduce a new type of substances with not only high specific heat but also high thermal diffusivity to Nb3Sn conductors, which is expected to work more effectively.
