Study on NbTi superconducting joint process for high field MRI magnet
고자장 MRI 마그네트를 위한 NbTi 초전도 접합 공정 연구
Abstract
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. Critical current of the joint of 28 filaments wires with 1.7 mm thickness of dimple was 450 A at 4.2K, 0.5T. Ic of the joint of 54 filaments wires with 2.0 mm thickness of dimple was 600 A at 4.2K, 2T. It is possible to manufacture MRI magnet by using these results.
