A Low-Fluorine Solution with the F/Ba Mole Ratio of 2 for the Fabrication of YBCO Films
Wei Wu, Feng Feng, Yue Zhao +8
In the reported low-fluorine MOD-YBCO studies, the lowest F/Ba mole ratio of the precursor solution was 4.5. However, further lowering the F/Ba ratio is important according to the…
Evaluation of the effect of edge cracks on critical current degradation in REBCO tapes under tensile stress
Zhirong Yang, Peng Song, Mingzhi Guan +2
The slitting process used for fabrication of REBa2Cu3Ox (REBCO, RE=Rare earth) tapes of required width will greatly improve production efficiency and reduce production costs. Howev…
Critical Current Survival in YBCO Superconducting Layer of the Delaminated Coated Conductor
Feng Feng, Qishu Fu, Timing Qu +8
High temperature superconducting coated conductor (CC) could be practically applied in electric equipment due to its favorable mechanical properties and the critical current perfor…
Experimental and numerical study on current distribution in parallel co-wound no-insulation coils
Yulong Liu, Peng Song, Mianjun Xiao +4
No-insulation (NI) coils are known for their high thermal stability and self-protection features due to turn-to-turn contacts. Parallel co-winding is a promising method to reduce t…
Screening current effect on the stress and strain distribution in REBCO high-field magnets: experimental verification and numerical analysis
Yufan Yan, Canjie Xin, Yunfei Tan +1
Besides screening-current-induced magnetic fields (SCIF), the shielding effect in high-Tc coated conductors also has an strong influence on its strain distribution in a coil windin…
A Surrogate model for High Temperature Superconducting Magnets to Predict Current Distribution with Neural Network
Mianjun Xiao, Peng Song, Yulong Liu +7
Finite element methods (FEM) for high-temperature superconducting (HTS) magnets become time-consuming at larger scales, restricting the rapid optimization of meter-scale REBCO sole…
Accurate evaluation of the fractal dimension based on a single morphological image
Feng Feng, Binbin Liu, Xiangsong Zhang +4
Fractal dimension (D) is an effective parameter to represent the irregularity and fragmental property of a self-affine surface, which is common in physical vapor deposited thin fil…
