Available in PDF, EPUB and Kindle. Book excerpt: This report describes the potential impact that high-temperature superconductors (HTSs) may have on transportation by magnetically levitated vehicles. It is not intended as a planning document, but rather as an overview of potential HTS applications to magnetic-levitation (maglev) transportation. The present maglev program in the United States is summarized, and the present status of development of HTSs is described. Areas identified for possible impact on maglev technology are (1) liquid-nitrogen-cooled levitation magnets, (2) magnetic-field shielding of the passenger compartment, (3) superconducting magnetic energy storage for wayside power, (4) superconducting bearings for flywheel energy storage for wayside power, (5) downleads to continuously powered liquid-helium-cooled levitation magnets, and (6) liquid-hydrogen-cooled levitation magnets and linear motor propulsion windings. Major technical issues that remain to be resolved for the use of HTSs in maglev applications include thermal magnetic stability, mechanical properties, and critical current density at liquid-nitrogen temperatures.

Available in PDF, EPUB and Kindle. Book excerpt: What Is High Temperature Superconductivity High-temperature superconductors are operatively defined as materials that behave as superconductors at temperatures above 77 K, the boiling point of liquid nitrogen, one of the simplest coolants in cryogenics. All materials currently known to conduct at ordinary pressures become superconducting at temperatures far below ambient, and therefore require cooling. The majority of high-temperature superconductors are ceramic materials. On the other hand, Metallic superconductors usually work below −200 °C: they are then called low-temperature superconductors. Metallic superconductors are also ordinary superconductors, since they were discovered and used before the high-temperature ones.

Book excerpt: This study was undertaken to (1) evaluate the potential contribution of high-temperature superconductors (HTSCs) to the technical and economic feasibility of magnetically levitated (maglev) vehicles, (2) determine the status of maglev transportation research in the United States and abroad, (3) identify the likelihood of a significant transportation market for high-speed maglev vehicles, and (4) provide a preliminary assessment of the potential energy and economic benefits of maglev systems. HTSCs should be considered as an enhancing, rather than an enabling, development for maglev transportation because they should improve reliability and reduce energy and maintenance costs. Superconducting maglev transportation technologies were developed in the United States in the late 1960s and early 1970s. Federal support was withdrawn in 1975, but major maglev transportation programs were continued in Japan and West Germany, where full-scale prototypes now carry passengers at speeds of 250 mi/h in demonstration runs. Maglev systems are generally viewed as very-high-speed train systems, but this study shows that the potential market for maglev technology as a train system, e.g., from one downtown to another, is limited. Rather, aircraft and maglev vehicles should be seen as complementing rather than competing transportation systems. If maglev systems were integrated into major hub airport operations, they could become economical in many relatively high-density US corridors. Air traffic congestion and associated noise and pollutant emissions around airports would also be reduced. 68 refs., 26 figs., 16 tabs.

This book was released on with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Superconductors: Fundamentals, Applications, and Beyond Superconductors, with their remarkable ability to conduct electricity without resistance, have fascinated scientists and engineers since their discovery over a century ago. This preface aims to provide an overview of the content and scope of this book, intended for students, researchers, and professionals keen to understand and harness the extraordinary properties of superconducting materials. Historical Context and Scientific Milestones The phenomenon of superconductivity was first observed by Heike Kamerlingh Onnes in 1911 when he discovered that mercury exhibited zero electrical resistance at temperatures close to absolute zero. This groundbreaking discovery set the stage for a century of research, leading to the development of theories and materials that have expanded our understanding and application of superconductors. From the BCS theory proposed by John Bardeen, Leon Cooper, and Robert Schrieffer in 1957, which explained superconductivity in terms of electron pairs or "Cooper pairs," to the discovery of high-temperature superconductors in the 1980s, each milestone has brought us closer to practical and widespread use of these materials. Purpose and Audience The primary purpose of this book is to bridge the gap between theoretical knowledge and practical application, offering insights into how superconductors can revolutionize various fields. It is designed for a diverse audience, including undergraduate and graduate students in physics, materials science, and engineering, as well as researchers and industry professionals seeking a thorough understanding of superconductors. Acknowledgments This work would not have been possible without the contributions of many individuals and institutions. We extend our deepest gratitude to the researchers whose pioneering work laid the foundation for our current understanding of superconductivity. Special thanks go to our collaborators and reviewers who provided invaluable feedback and insights. Finally, we are grateful to our families for their unwavering support and patience throughout the writing process. Conclusion Superconductors represent one of the most exciting frontiers in modern science and technology. As you embark on this journey through the world of superconductivity, we hope you find the content enlightening and inspiring. May this book not only deepen your understanding but also spark new ideas and innovations in this fascinating field.

Download or read book Applications of Superconductivity written by H. Weinstock and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, in essence the proceedings of a NATO Advanced Study Institute with the same title, is designed to provide in-depth coverage of many, but not all, of the major current applications of superconductivity, and of many that still are being developed. It will be of value to scientists and engineers who have interests in the research and production aspects of the technology, as well as in the applications themselves. The ftrst three chapters (by Clarke, Vrba and Wikswo) are devoted to an understanding of the principles, fabrication and uses of SQUID magnetometers and gradiometers, with the greatest emphasis on biomagnetism and nondestructive evaluation (NDE). For the most part, traditional low-temperature superconductor (LTS) SQUIDs are used, but particularly for NDE, high-temperature superconductor (HTS) SQUIDs are proving useful and often more convenient. The succeeding three chapters (by Przybysz, Likharev and Chaloupka) cover broader aspects of superconducting electronics. The ftrst two of these deal primarily with digital L TS circuits, while the third discusses in great detail passive component applications using HTS materials. Currently, HTS ftlters are undergoing intense J3-site testing at cellular telephone base stations. While it is clear that HTS ftlters outperform conventional ftlters in reducing signal loss and allowing for more channels in a given bandwidth, it isn't yet certain that the cellular telephone industry sees sufficient economic beneftts to make a ftrm decision to use HTS ftlters universally in its systems. If this application is generally adapted, the market for these ftlters should be quite large.
