This book was released on 2008. Persistent Current in Coils Made Out of Second Generation High Temperature Superconductor Wire available in PDF, EPUB and Kindle. We report the results of an experimental study of a persistent coil made out of YBa2Cu3O7 coated conductors. The magnitude of the persistent current and the rate of decay were investigated. Two distinct modes of relaxation are evident -- one is flux creep and the other, which is much faster, is of less obvious origin. Our conclusion is that the persistent current in such a coil can be large enough and decay slowly enough so that coated conductors can be used to make persistent coils for a variety of applications.

This book was released on 2011-06-24. Second-Generation High-Temperature Superconducting Coils and Their Applications for Energy Storage available in PDF, EPUB and Kindle. Second-Generation High-Temperature Superconducting Coils and Their Applications for Energy Storage addresses the practical electric power applications of high-temperature superconductors. It validates the concept of a prototype energy storage system using newly available 2G HTS conductors by investigating the process of building a complete system from the initial design to the final experiment. It begins with a clear introduction of the related background and then presents a comprehensive design of a superconducting energy storage system that can store maximum energy using a limited length of superconductors. The author has created a modeling environment for analysis of the system and also presents experimental results that are highly consistent with his theoretical calculations.

Download and read online ebook Superconducting Accelerator Magnets write by K.-H. Mess. This book was released on 1996. Superconducting Accelerator Magnets available in PDF, EPUB and Kindle. The main topic of the book are the superconducting dipole and quadrupole magnets needed in high-energy accelerators and storage rings for protons, antiprotons or heavy ions. The basic principles of low-temperature superconductivity are outlined with special emphasis on the effects which are relevant for accelerator magnets. Properties and fabrication methods of practical superconductors are described. Analytical methods for field calculation and multipole expansion are presented for coils without and with iron yoke. The effect of yoke saturation and geometric distortions on field quality is studied. Persistent magnetization currents in the superconductor and eddy currents the copper part of the cable are analyzed in detail and their influence on field quality and magnet performance is investigated. Superconductor stability, quench origins and propagation and magnet protection are addressed. Some important concepts of accelerator physics are introduced which are needed to appreciate the demanding requirements on field quality in large storage rings. The operational experience with the superconducting HERA collider serves as an illustration. Finally superconducting correction coils and practical construction and fabrication methods of accelerator magnets are discussed. The physical and technical principles described in the book are substantiated with a wealth of experimental data on multipoles, persistent- and eddy-current effects, quench performance and much more.

This book was released on 2021-01-14. Development of high-temperature superconductor cables for high direct current applications available in PDF, EPUB and Kindle. A design process for HTS DC cables was developed for high current applications. Based on the design process, a 35 kA HTS DC cable demonstrator was developed. The superconducting elements of the demonstrator were manufactured and tested individually at 77 K. Afterwards, the demonstrator cable was assembled and tested at 77 K. The assembled demonstrator successfully reached 35 kA at 77 K and self field conditions.
