By optimizing these parameters, we were able to determine the precise conditions for obtaining a high-purity Tl-1223 phase. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to examine the crystalline structure and morphology, while magnetic properties were investigated using SQUID magnetometry. The phase diagram provides critical insights into the stability of Tl-1223, guiding future synthesis efforts. Our magnetic measurements confirmed superconducting behavior with a critical temperature of approximately 120 K, validating the optimized synthesis process. Though primarily focused on phase formation, this research also opens up the potential for applying Tl-1223 in the Future Circular Collider (FCC) as a beam screen coating material. The superconducting properties of Tl-1223 make it a promising candidate for overcoming the limitations of traditional materials under FCC operational conditions. Future work will explore the preparation of Tl-1223 films for this application.","PeriodicalId":13104,"journal":{"name":"IEEE Transactions on Applied Superconductivity","volume":"35 5","pages":"1-5"},"PeriodicalIF":1.7,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the barriers for spreading BEV use is definitely long charging time. Shorter charging time would be realized with very high power, higher voltage and higher current. Although conventional chargers, which are based on AC-to-DC (ACDC) power converters, receiving power from utility grids shows technologically high efficiency, the overall efficiency from power generation to battery charge is NOT so high due to multiplied efficiencies through the power path going down, typically below 90%. DC-to-DC (DCDC) boost converter technology allows us not only to make good use of renewable energy but to achieve very high charging efficiency by the way of direct power receiving from renewable sources. The bottle neck for large current charging is the current capacity of conventional inductors, which would be drastically improved by replacing the normal inductor to “superconducting coil”. Our group has designed and demonstrated a superconducting DCDC (SCDCDC) double-boost converter to prove the excellent potential as ultra-fast charger providing high voltage with large currents. We designed the SCDCDC by using Bi2223 and MgB2 coils. The converter with the MgB2 inductor which has already demonstrated nominal operation with liquid hydrogen cooling in a previous research, showed high efficiencies larger than 95% up to 15 kW of output power operations with liquid helium cooling.","PeriodicalId":13104,"journal":{"name":"IEEE Transactions on Applied Superconductivity","volume":"35 5","pages":"1-5"},"PeriodicalIF":1.7,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is useful to use a flux pump to power superconducting magnets in a non-contact manner. In order to facilitate the rapid excitation and current modulation of superconducting magnets updated flux pump was designed to deliver a higher DC voltage output. The distribution of magnetic flux density was analyzed using COMSOL Multiphysics, which helped in determining the optimal design parameters. We extended the coupling interval of the updated flux pump to 447 mm. The updated flux pump was tested at 77 K in liquid nitrogen, with a maximum output voltage of 118.24 mV, the updated flux pump can charge an insulated (INS) double pancake coil (DPC) with 75 turns per layer to a maximum current of 88.90 A in 9 s, exceeding the critical current (<inline-formula><tex-math>${I}_{C}$</tex-math></inline-formula>) for the DPC.

High-temperature superconducting materials possess the advantages of zero resistance and high current-carrying capacity. Building upon the conventional high-speed electromagnetic levitation train, this article proposes a parallel hybrid-excited superconducting electromagnetic support system that incorporates both high-temperature superconducting and conventional components. By considering the symmetry of the support arm and electromagnetic field, certain normally conducting electromagnets are replaced with superconducting ones. Utilizing the conventional electromagnetic support system as a basis, we conducted finite-element simulation to establish and analyze the superconducting hybrid electromagnetic support and linear motor traction system. At suspension gaps of 15 and 20 mm, superconducting electromagnets contribute 80% of the suspension force without significant traction loss, while normally conducting electromagnets require smaller currents for system support and traction functions. The suspension gap can be effectively controlled within a certain safe range (15–20 mm) by maintaining a constant current in the electromagnetic coil.","PeriodicalId":13104,"journal":{"name":"IEEE Transactions on Applied Superconductivity","volume":"35 3","pages":"1-5"},"PeriodicalIF":1.7,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These techniques play a vital role in quality assurance and quality control (QA/QC), ensuring the reliability and performance of HTS conductors and applications throughout the production cycle. We have developed a range of in-house devices for R2R measurements at the University of Houston and Princeton Plasma Physics Laboratory. These include one-dimensional (1D) scan using a magnetic circuit (MC) and two-dimensional (2D) magnetic field mapping systems based on scanning probe array microscope (SPAM) or scanning probe microscopy (SPM). Each technique offers distinct advantages: the MC system provides ultra-fast scanning speeds, ideal for rapid inspection in large-scale industrial production; the high-resolution SPM delivers detailed insights for conductor research and development; and the SPAM, with its simpler mechanical setup, can be upgraded for higher field and lower temperature conditions with a balanced 2D resolution. We compared the magnetization and detection capabilities of these techniques through experiments on rare-earth barium copper oxide (REBCO) coated conductor samples, with data analysis supported by numerical simulations. Based on our comprehensive comparative studies, we propose enhancements for each measurement system and provide guidelines for selecting the optimal technique combinations to meet specific application requirements.","PeriodicalId":13104,"journal":{"name":"IEEE Transactions on Applied Superconductivity","volume":"35 5","pages":"1-5"},"PeriodicalIF":1.7,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During magnet quench, high current density can quickly lead to local temperature increase and temperature gradient that can potentially damage the coil. This paper presents an analysis of the mechanical impact of the large thermal gradients. The study employs 3D finite element method (FEM) simulations to investigate the mechanical responses of second-generation HTS tapes to different hotspot temperature profiles. The focus is on analyzing the axial tape strain, normal stress and the various shear stresses in tape layer interfaces. We consider both single tapes and tape stacks. The normal zone propagation is not simulated, but we examine different end-temperature profiles to identify the critical thermal conditions that may lead to too large strain or stress. The results suggest that induced axial strain can exceed the elastic limit or lead to irreversible critical current reduction. Also, the shear stress computed using the Mohr-Coulomb criterion may reach very high values potentially leading to mixed-mode delamination. Future studies are needed to verify the damage methods after high temperatures and help in determining the maximum safe temperature in magnet design. The results highlight the importance of mechanical boundary conditions in this type of numerical or experimental study.","PeriodicalId":13104,"journal":{"name":"IEEE Transactions on Applied Superconductivity","volume":"35 5","pages":"1-6"},"PeriodicalIF":1.7,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10916518","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143654961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
