Temperature distribution and surface morphology are simulated by finite-element method. It is proposed that a Gaussian crater appears in the mitigation site, which width and depth are dependent on the laser parameters. Following, the effects of frequency, duty cycle, and beam diameter on the size of mitigation are also analyzed. For the same laser power, reducing the above three parameters may lead to higher temperature at the spot center. However, the effects on the size of ablation and melting are inconsistent. The results show that a small laser beam is suitable for smaller and deeper defects, whereas a big laser beam is suitable for bigger and shallower defects. In addition, frequency and duty cycle have a significant influence on the ablation. Large duty cycle or high frequency may reduce the ablation, and thereby, the surface of the ablation profile becomes smoother after melted material recondense. Correspondingly, the mitigation process is mainly ablation for low duty cycle or low frequency.]]>24514480<![CDATA[Magnetic Integration Technology in Controllable Reactor of Transformer Type Constituted by Various Magnetic Materials]]>24515307<![CDATA[Novel Decoupling Model-Based Predictive Current Control Strategy for Flux-Switching Permanent-Magnet Synchronous Machines With Low Torque Ripple and Switching Loss]]>245151505<![CDATA[Novel Linear Iteration Maximum Power Point Tracking Algorithm for Photovoltaic Power Generation]]>245161447<![CDATA[Parameters Analysis and Optimization Design for a Concentric Magnetic Gear Based on Sinusoidal Magnetizations]]>245151499<![CDATA[Study on Switching Overvoltage in Off-Shore Wind Farms]]>24515926<![CDATA[Methodology and Equipments for Analog Circuit Parametric Faults Diagnosis Based on Matrix Eigenvalues]]>24516581<![CDATA[Novel Flux-Regulatable Dual-Magnet Vernier Memory Machines for Electric Vehicle Propulsion]]>245151390<![CDATA[AC and Impulse Dielectric Strength of Polymer Materials Under Tensile Stress at 77 K]]>24514951<![CDATA[Modular Stator High Temperature Superconducting Flux-Switching Machines]]>24515990<![CDATA[Automatic Segmentation of 3-D Brain MR Images by Using Global Tissue Spatial Structure Information]]>24515457<![CDATA[New Hybrid Damping Strategy for Grid-Connected Photovoltaic Inverter With LCL Filter]]>245182436<![CDATA[A New Internal Detection Method for Fluid Transportation Pipeline Leak Based on Active Electrolocation]]>24515519<![CDATA[Parametric Characterization and Macroscopic Quantum Tunneling of <inline-formula> <tex-math notation="TeX">$hbox{Nb}/hbox{AlO}_{rm x}/hbox{Nb}$</tex-math></inline-formula> Josephson Junctions]]>x/Nb Josephson including its critical current and capacitance which determine the dynamic energy consumption and speed of the superconducting electronics have been measured.

This paper presents the fabrication and characterization of two types of in situ powder-in-tube processed mono (pure) and multifilament (carbon doped) MgB_{2} cables with different twist pitch lengths; thereby making them possible candidates for industrial AC applications. Critical current is not influenced by the cabling that results in various twist lengths. The total critical current of the braided cables is obtained by multiplying the critical current of six single wires without any dissipation. The critical current density (J_{c}) of pure (mono) and carbon doped (18-filament) six stranded cable reached 10000 A/cm^{2} at 5.5 and 10 T, respectively; without any observable deleterious effect caused by varying the twist pitch. The engineering current density (J_{e}) of both cables reached the same value of 10000 A/cm^{2} at 3.5 and 6.5 T, respectively. Compared to the literature, this work reports some of the highest J_{c} and J_{e} values for carbon doped multifilament cables that remain unaffected upon varying the twist pitch. The present results are promising in terms of scaling up these cables to industrial lengths for transformers, fault-current limiters-based applications and paves the way for the development of optimal protocols for practical functionality.]]>24514576<![CDATA[Investigation of Orthogonal Experiment for Fabrication of a Soldering Joint for a 4-T HTS Coil]]>24515693<![CDATA[Vision Inspection Methods for Uniformity Enhancement in Long-Length 2G HTS Wire Production]]>24515988<![CDATA[Effects of Second Milling Time on Temperature Dependence and Improved Steinmetz Parameters of Low Loss MnZn Power Ferrites]]>3 at wide temperature range (25 °C ~ 120 °C). The improved Steinmetz parameters reveal that the absolute value of ct_{0}, ct_{1} and ct_{2} of all samples present decreasing trends along with the increasing of frequency. Moreover, the minimum power loss temperature moves to a lower temperature, the total effect of temperature on power loss becomes smaller, and the temperature stability of low loss MnZn power ferrites becomes better.]]>24514635<![CDATA[High-Specific-Capacitance Supercapacitor Based on Vanadium Oxide Nanoribbon]]>24514517<![CDATA[Magnetic Anisotropic Properties Measurement and Analysis of the Soft Magnetic Composite Materials]]>245141000<![CDATA[Design Considerations in <inline-formula> <tex-math notation="TeX">$hbox{MgB}_{2}$</tex-math></inline-formula>-Based Superconducting Coils for Use in Saturated-Core Fault Current Limiters]]>2-based coil.

The results are discussed about Cooper pairs existing. Tunneling spectra were measured for Y-Bi2212 crystal-SiO-Ag planar junctions. For superconducting samples the V-shaped gap structure and zero bias conductance peaks (ZBCP) were observed. While neither superconducting gap nor ZBCP was observed for insulator samples. These results suggest that Cooper pairs break up on the insulating side of superconductor-insulator transition (SIT). We also measured tunneling spectra on (Bi_{1-y}Pb_{y})_{2}Sr_{2}Ca_{1-x}Y_{x}Cu_{2}O_{8+δ} samples.

An efficient way to improve I_{c} is to increase the thickness of YBCO film without much reduction in critical current density (J_{c}). Metallorganic solution deposition (MOD) is a traditional method to fabricate YBCO films while it takes time as long as 10h during the pyrolysis process. In comparison, Low-Fluorine MOD (LF-MOD) method is applied to reduce the pyrolysis time to less than 2h. In this paper, we successfully obtain YBCO thick films up to 1.7μm by double dip coating process using low-fluorine MOD method. Though wrinkles are frequently observed on the surface of the first layer after pyrolysis at 400 °C for 0.5h, the surface of the final double coated YBCO thick film is homogeneous and cracks are hardly found. Further tests show relatively good c-axis orientation and J_{c} value of about 10^{5} A/cm^{2} at 77K. With an optimization for the pyrolysis and crystallization processes, better superconducting properties of YBCO thick film are expected.]]>24513478<![CDATA[Progress in Production and Performance of Second Generation (2G) HTS Wire for Practical Applications]]>c (77K, self-field) of 300 ~ 500 A/cm-w and piece lengths of a few hundred meters are being routinely produced. Past and ongoing demonstration projects using the 2G HTS wires suggest that the practical application of this new material is appealing, promising and challenging. Further improvement in wire performance is desired and wire price is to be reduced. In this paper, important properties of 2G wires such as uniformity, in-field Ic and electromechanical behaviors are described. Recent technology advancements in using 2G HTS wire for practical applications are discussed.]]>24515861<![CDATA[Magnetization of 2-G Coils and Artificial Bulks]]>245151255<![CDATA[A Novel Calorimetric Method for Measurement of AC Losses of HTS Tapes by Optical Fiber Bragg Grating]]>24514519<![CDATA[Design, Fabrication, and Operation of the Cryogenic System for a 220 kV/300 MVA Saturated Iron-Core Superconducting Fault Current Limiter]]>24514739<![CDATA[Review of AC Loss Measuring Methods for HTS Tape and Unit]]>24516850<![CDATA[Parameter Identification and Calculation of Return Voltage Curve Based on FDS Data]]>24515603<![CDATA[Characterization of Partial Discharge With Polyimide Film in <inline-formula> <tex-math notation="TeX">$hbox{LN}_{2}$</tex-math></inline-formula> Considering High Temperature Superconducting Cable Insulation]]>2) and polyimide film have been used as a coolant and insulation in HTS cable systems. Partial discharge (PD) events may lead to material degradation and total breakdown. PD testing is an important quality check for the insulation of HTS cable. Thus it is necessary to consider PD for the insulation testing in LN_{2} which is generated in void defects of the insulation layers. The PD characterizations of polyimide film in different defects were investigated under 50 Hz AC voltages in LN_{2} and at room temperature (298 K). The results show that the number of discharges and the discharge quantity increase with the increasing of the applied voltage and the defect size. The PD inception voltage decreases when the void defect diameter enlarged and it is higher in LN_{2} than that at room temperature. The maximum field strength for HTS tape insulation increases with the defect close to the tape boundary and the addition of contaminant relative permittivity. Obtained results at cryogenic temperature provide necessary information for insulation design and pre-shipment inspections of HTS cable system.]]>24515318<![CDATA[Dielectric Characteristics of Laminated Paper and Polymer Sheets Used for Lapping Dielectric Structure at 77 K]]>24514838<![CDATA[A Universal LabVIEW-Based HTS Device Measurement and Control Platform and Verified Through a SMES System]]>245151380<![CDATA[Fault-Tolerant Routing Algorithm Simulation and Hardware Verification of NoC]]>245151016<![CDATA[Research on Characteristics of Noncontact Capacitive Voltage Divider Monitoring System Under AC and Lightning Overvoltages]]>24513340<![CDATA[Research on a New Type of Overvoltages Monitoring Sensor and Decoupling Technology]]>24514454<![CDATA[IEEE Transactions on Applied Superconductivity subject categories for article numbering]]>245C3C393<![CDATA[IEEE Transactions on Applied Superconductivity information for authors]]>245C4C4106
