Book Description
The authors begin this book with a systematic overview of superconductivity, superconducting materials, magnetic levitation, and superconducting magnetic levitation - the prerequisites to understand the latter part of the book - that forms a solid foundation for further study in High Temperature Superconducting Magnetic Levitation (HTS Maglev). This book presents our research progress on HTS Maglev at Applied Superconductivity Laboratory (ASCLab) of Southwest Jiaotong University (SWJTU), China, with an emphasis on the findings that led to the world‘s first manned HTS Maglev test vehicle "Century". The book provides a detailed description on our previous work at ASCLab including the designing of the HTS Maglev test and measurement method as well as the apparatus, building "Century", developing the HTS Maglev numerical simulation system, and making new progress on HTS Maglev. The final parts of this book discuss research and prototyping efforts at ASCLab in several adjacent fi elds including HTS Maglev bearing, Flywheel Energy Storage System (FESS) and HTS maglev launch technology. We hope this book becomes a valuable source for researchers and engineers working in the fascinating field of HTS Maglev science and engineering.

Book Description
Superconducting nanowire singe-photon detectors (SNSPD) are promising detectors in the field of applications, where single-photon resolution is required like in quantum optics, spectroscopy or astronomy. These cryogenic detectors gain from a broad spectrum in the optical and infrared range and deliver low dark count rates and low jitter times.

Ultra-Low Field Nuclear Magnetic Resonance
Author: Robert Kraus Jr.
Publisher: Oxford University Press
ISBN: 0199347883
Category : Medical
Languages : en
Pages : 266
Book Description
This book is designed to introduce the reader to the field of NMR/MRI at very low magnetic fields, from milli-Tesla to micro-Tesla, the ultra-low field (ULF) regime. The book is focused on applications to imaging the human brain, and hardware methods primarily based upon pre-polarization methods and SQUID-based detection. The goal of the text is to provide insight and tools for the reader to better understand what applications are best served by ULF NMR/MRI approaches. A discussion of the hardware challenges, such as shielding, operation of SQUID sensors in a dynamic field environment, and pulsed magnetic field generation are presented. One goal of the text is to provide the reader a framework of understanding the approaches to estimation and mitigation of low signal-to-noise and long imaging time, which are the main challenges. Special attention is paid to the combination of MEG and ULF MRI, and the benefits and challenges presented by trying to accomplish both with the same hardware. The book discusses the origin of unique relaxation contrast at ULF, and special considerations for image artifacts and how to correct them (i.e. concomitant gradients, ghost artifacts). A general discussion of MRI, with special consideration to the challenges of imaging at ULF and unique opportunities in pulse sequences, is presented. The book also presents an overview of some of the primary applications of ULF NMR/MRI being pursued.

Pages : 245
Book Description
Hands-on guide for scientists and engineers on how to use SQUID technology This practical book covers SQUID (superconducting quantum interference device) readout electronics and magnetometric systems. It illustrates their many practical applications in measuring extremely subtle magnetic fields and shows how the technique is developing into an enabling technology for many applications, such as biomagnetic imaging and geophysical prospecting. Clear and comprehensive, the book builds a bridge for scientists and engineers to fill in potential know-how gaps for all who work on SQUID systems and their practical applications. It helps make key words like readout electronics, flux quantization, Josephson effects, and noise contributions completely understandable to all who design and use simple and robust SQUID systems. Beginning with an introduction to the subject, SQUID Readout Electronics and Magnetometric Systems for Practical Applications offers in-depth chapter coverage of: Josephson junctions; dc SQUID’s I-V characteristics and its bias modes; functions of the SQUID's readout electronics; direct readout scheme (DRS); SQUID magnetometry system and SQUID parameters; flux modulation scheme (FMS); and flux feedback concepts and parallel feedback circuit. Other sections examine: analyses of the "series feedback coil (circuit)" (SFC); weakly damped SQUID; two-stage and double relaxation oscillation readout schemes; and radio-frequency (rf) SQUID. · Provides a unique view of how simplicity and robustness are crucial for practical SQUID systems in applications · Focuses on the readout electronics of SQUID systems, particularly the advantages and disadvantages of the various systems · Helps materials scientists, physicists, and engineers overcome various major know-how barriers in order to understand the important challenges and to design practical SQUID systems · Largely documents the joint achievements accomplished in the cooperation between SIMIT and FZJ in the field of superconducting electronics SQUID Readout Electronics and Magnetometric Systems for Practical Applications is an excellent book for all materials scientists, electrical engineers, and physicists who can benefit from SQUID systems and their applications.

Electron-phonon Interaction And Lattice Dynamics In High Tc Superconductors
Author: Han Zhang
Publisher: World Scientific
ISBN: 9813271159
Category : Science
Languages : en
Pages : 358
Book Description
Understanding the mechanism of the high-temperature superconductors has been a very important topic in condensed matter physics. Researchers have been trying to explain the role of electron-phonon interaction (EPI) in cuprates. Some important properties of the cuprates could not be explained by conventional BCS theory. This book contains the experimental and theoretical studies on the EPI. The experimental part covers the results of angle-resolved photoemission spectroscopy (ARPES), isotopic effect, elastic neutron scattering study of electron-phonon, lattice role and so on. The theoretical part covers the electron-phonon, polaron and bipolaron, effect of lattice, fine structure in the tunnelling spectra of electron-doped cuprates, identification of the bulk pairing symmetry in high-temperature superconductors.Students and researchers interested in high-temperature superconductors, especially the EPI in cuprates will find this title very useful.

Modular Systems for Energy and Fuel Recovery and Conversion
Author: Yatish T. Shah
Publisher: CRC Press
ISBN: 1000011739
Category : Technology & Engineering
Languages : en
Pages : 612
Book Description
Modular Systems for Energy and Fuel Recovery and Conversion surveys the benefits of the modular approach in the front end of the energy industry. The book also outlines strategies for managing modular approaches for fossil, renewable, and nuclear energy resource recovery and conversion with the help of successful industrial examples. The book points out that while the modular approach is most applicable for distributed and small-scale energy systems, it is also often used for parts of large-scale centralized systems. With the help of successful industrial examples of modular approaches for energy and fuel recovery and conversion, the book points out the need for more balance between large-scale centralized systems and small-scale distributed systems to serve the energy needs of rural and isolated communities. Coal, oil, natural gas, hydrogen, biomass, waste, nuclear, geothermal solar, wind, and hydro energy are examined, showing that modular operations are very successfully used in all these components of the energy industry. Aimed at academic researchers and industry professionals, this book provides successful examples and analysis of the modular operation for energy and fuel recovery and conversion. It is also a reference for those who are engaged in the development of modular systems for energy and fuel recovery and conversion.
