Status of MgB_2 superconducting wires at Sam Dong Co., Ltd. in Korea

摘要

Magnesium diboride (MgB_2) superconducting wire has attracted more attention for various applications due to its high critical transition temperature (39 K) and relatively facile manufacture. Over the past few years, many studies have been made for specific 1.5 T magnetic resonance imaging (MRI), superconducting transmission cable, and superconducting magnetic energy storage (SMES). For this, a km-scale length MgB_2 wire is mandatorily required with superior superconducting properties and microstructural homogeneity along the rolling direction. In this paper, we will introduce the status of customized MgB_2 wires in Sam Dong Co., Ltd., Korea.
