Journal ArticleDOI
The effects of co-wound Kapton, stainless steel and copper, in comparison with no insulation, on the time constant and stability of GdBCO pancake coils
Tae Sung Lee,Young Jin Hwang,Jiho Lee,Woo Seung Lee,Jinsub Kim,Seunghyun Song,Min Cheol Ahn,Tae Kuk Ko +7 more
TL;DR: In this article, the electrical characteristics of HTS coils based on the turn-to-turn inserted materials and conditions were presented. And the experimental results showed that the properties of materials inserted into the coil can control the time constant.
Journal ArticleDOI
Spatial and Temporal Variations of a Screening Current Induced Magnetic Field in a Double-Pancake HTS Insert of an LTS/HTS NMR Magnet
TL;DR: Experimental and simulation results of a screening current induced magnetic field (SCF) in a high temperature superconductor (HTS) insert that constitutes a low-/high-temperature super Conductor (LTS/HTS), NMR magnet are presented.
Journal ArticleDOI
Analysis of a Joint Method Between Superconducting YBCO Coated Conductors
Dong Keun Park,Min Cheol Ahn,Ho Min Kim,Haigun Lee,Ki Sung Chang,Sand Jin Lee,Seong Eun Yang,Tae Kuk Ko +7 more
TL;DR: In this paper, an analysis on the optimum lap joint method of the YBCO coated conductor (CC) wire was performed with low temperature InBi solder, and the characteristics of jointed CC tape were evaluated from the V-I curve and contact resistance was derived from experimental results.
Journal ArticleDOI
Operation and performance analyses of 350 and 700 MHz low-/high-temperature superconductor nuclear magnetic resonance magnets: A march toward operating frequencies above 1 GHz
Seungyong Hahn,Juan Bascunan,Haigun Lee,E.S. Bobrov,Woo-Seok Kim,Woo-Seok Kim,Min Cheol Ahn,Y. Iwasa +7 more
TL;DR: In this paper, the authors present extensive performance analyses of the two LTS/HTS NMR magnets, including spatial homogeneity and temporal stability of LH350 and LH700, examined with harmonic analysis.
Journal ArticleDOI
Proof-of-Concept of a Smart Fault Current Controller With a Superconducting Coil for the Smart Grid
Min Cheol Ahn,Tae Kuk Ko +1 more
TL;DR: A concept of the smart FCC, a fault current controller (FCC) named “smart FCC” that can not only limit but also control the current when a fault occurs is introduced and proved.
