초록

NbTi/Cu superconducting wires were jointed inserting the NbTi filaments into Cu/NbTi sleeve and pressing it. When the NbTi filaments were inserted into Cu/NbTi sleeve additional NbTi filaments were inserted together to increase the numbers of filaments in the hole of sleeve. The thickness of sleeves and dimples were changed to get optimal factor for high Ic of joint Critical current of the joint with additional NbTi Filaments and 17mm thickness of dimple was 450 A at 4.2K, 0.5T.
