Both strength and modulus are usually amplified at cryogenic temperatures, so properties at both cryogenic and room temperatures must be characterized before the materials can be used for applications. In this study, we investigated a nickel-based alloy whose Young's modulus is higher than that of the stainless steels that have commonly been relied on as reinforcement materials in cryogenic environments. Our test alloy was subjected to a type of thermo-mechanical processing that strengthens the alloy through very fine planar defects. We first deformed the alloy to various magnitudes at room temperature, and we then measured its properties at both cryogenic and room temperatures. Finally, we assessed the properties (at both temperatures) of the materials that were deformed to different deformation strains at room temperature. We found that our test alloy had anisotropy in both elastic modulus and mechanical strength and had more resistance to plastic deformation at cryogenic temperatures than at room temperatures. We then investigated physical property changes in various magnetic fields and at various cryogenic temperatures. This paper summarizes 1) the changes that occurred in the microstructure of our alloy and 2) the properties desirable for effective reinforcement materials.","PeriodicalId":13104,"journal":{"name":"IEEE Transactions on Applied Superconductivity","volume":"35 5","pages":"1-5"},"PeriodicalIF":1.7,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748828","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}

The magnet cross-section has been carefully optimized for the HE type of the SCQ magnet to achieve a good field quality and superconductor efficiency in spite of the expected iron saturation.

Although some simulations have been performed, the detailed physics of its operation is not clear. Therefore, we are studying the behavior of superconducting nanostructured devices through numerical simulations using the thermal diffusion equation and the time-dependent Ginzburg-Landau (TDGL) equation. We previously reported on the simulation of a simple T-shaped line with a current confluence of a constant bias current and a short-time gate current. As the next step, we report the simulation on a T-shaped device with a constriction in the channel.

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.

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}

Electric aircraft enabled by HTS-based systems, such as motors and energy distribution cables, are highlighted among those applications. In this context, there is an urgent need for machines with specific powers ranging from 15 to 30 kW/kg, which can leverage the inherent compactness and low weight of HTS motors. This work presents an electromechanical drive built by an axial-flux type motor with an HTS rotor, where the latter uses HTS REBCO tapes. The drive enables the electronic changing of the number of magnetic poles generated by a double stator with conventional windings. Consequently, the rotor must dynamically reconfigure its distribution of currents in the tapes to adapt to different numbers of poles. The prototype of the polyphase power electronics converter for the drive is also introduced. It allows for generating 24 voltages with frequency, voltage, and phase shift defined by the user according to the desired number of poles. Despite its increased complexity, the converter and the motor allow for improved performance compared to conventional drives. Preliminary experimental results are presented to support the discussion and outline prospects for the proposed concept in the framework of electric aircraft applications.","PeriodicalId":13104,"journal":{"name":"IEEE Transactions on Applied Superconductivity","volume":"35 5","pages":"1-6"},"PeriodicalIF":1.7,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748827","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}

The distribution of magnetic flux density was analyzed using COMSOL Multiphysics, which helped in determining the optimal design parameters.
