Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Impact of Vibration-induced Disturbances on Superconducting Magnets by : Elizabeth Ann Scholle
Download or read book Impact of Vibration-induced Disturbances on Superconducting Magnets written by Elizabeth Ann Scholle and published by . This book was released on 1995 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: In magnetic levitation (maglev) systems, the interaction between the superconducting magnets (SCMs) and the discrete ground coils causes electromagnetic and mechanical vibrations. These disturbances limit the performance of the maglev, as occurred in the Japanese MLU002 maglev. Here I examine how the electromagnetic oscillations are translated into mechanical vibrations and the subsequent effects on thermal stability. Dynamic circuit theory is used to determine the harmonic forces on the SCM. The levitation, guidance and propulsion forces are represented by the summation of steady state forces and an oscillatory component due to the ground coils being discrete. The oscillatory component drives the vibrational response. Normal mode analysis is performed to determine the transient and steady state motion of the conductor. The energy dissipated within the conductor due to hysteretic and viscous damping is then determined from the conductor displacements. This energy forms the input to a two-dimensional, transient, thermal stability analysis. The results from the analysis methods described here have been qualitatively compared with experimental results obtained at the Japanese Railway Technical Research Institute's vibration test stand. Results indicate excellent qualitative agreement in functional form. Results show how variations in the mechanical properties of the conductor affect the stability of the MLU002 as a function of velocity. It was found that the vibrational resonances occur at certain combinations of Young's modulus and vehicle velocity, quenching the magnets. The use of high temperature superconductors has also been explored. The strains induced by the vibration of the conductor are detailed. Provided that the resonances can be avoided, the strains experienced by the conductor should not be problematic. The use of cryocoolers operating in the range of 20-40 K is also shown to be possible for maglev applications. The ability to predict the velocity at which resonances, and hence quenches, occur allows future maglevs to be designed to avoid such quenches by shifting the critical velocity above that intended for operation. An example of this is shown, using system parameters from the design of the new Japanese maglev test facility in the Yamanashi prefecture.
