초록

$Nb_3Sn$ superconducting wires were fabricated in order to investigate the effect of pre-heat treatment for internal tin process. 2 types of Sn reservoir were fabricated. One was arranged one large Sn reservoir in the center of wire, the other arranged several Sn reservoirs inthe wire. Diffusion of Sn is better in the strand divided Sn equally than in the strand had one large Sn reservoir during pre heat-treatment. Critical current was better in the wires divided Sn reservoirs uniformly after whole heat treatment.
