Over the years the aim of the International Conference on Magnet Technology has been the exchange of information on the design, construction and operation of magnets for a variety of applications, such as high energy physics, fusion, electrical machinery and others. The aim has included advances in materials for magnet conductors, insulators and supporting structures. Since its inception the focus of the International Conference on Magnet Technology has gradually shifted to superconducting magnets. Now almost all papers are related to superconductivity. The 11th International Conference on Magnet Technology (MT-11) was organized by the combined efforts of the Institute of Electrical Engineers of Japan, the Association for Promotion of Electrical, Electronic and Information Engineering, and the Tokyo Section of the IEEE. The Conference was held at the Tsukuba University Hall, Tsukuba, Japan, from 28 August to 1 September 1989, courtesy ofthe University ofTsukuba. The Tsukuba University Hall was large enough to host invited talks, parallel sessions, poster sessions and industrial exhibitions. 461 participants from 19 countries registered for MT-ll, and 280 invited and contributed papers were presented. The papers were reviewed not only by the Program Committee but also by foreign participants. Working sessions and social events were characterized by a truly international atmo sphere. Scientific as well as cultural excursions were organized so that foreign visitors could experience the spirit of modern Japan. 26 companies, of which 8 were from Western countries, participated in the industrial exhibition which featured diverse products and services of interest to the magnet community.

This book contains the proceedings of the 16th ICEC/ICMC Conference, held in Kitakyushu, Japan, on 20th-24th May 1996. The Proceedings are presented in three volumes containing a total of 476 papers from 1484 authors. The proceedings covers the main areas of: Large Scale Refrigeration. Cryocoolers. Cryogenic Engineering. Space Cryogenics. Application of Superconductivity. Oxide Superconductors. Metallic Superconductors. Metallic Materials. Non Metallic Materials.In addition there are seven Plenary Lectures covering such diverse topics as commercialization of high-Tc superconductors, the continuing development of the Maglev system in Japan, and the Large Hadron Collider project. The Proceedings comprise an excellent and up-to-date summary of research and development in the fields of Cryogenics and Superconductivity.

This open access book is written by world-recognized experts in the fields of applied superconductivity and superconducting accelerator magnet technologies. It provides a contemporary review and assessment of the experience in research and development of high-field accelerator dipole magnets based on Nb3Sn superconductor over the past five decades. The reader attains clear insight into the development and the main properties of Nb3Sn composite superconducting wires and Rutherford cables, and details of accelerator dipole designs, technologies and performance. Special attention is given to innovative features of the developed Nb3Sn magnets. The book concludes with a discussion of accelerator magnet needs for future circular colliders.
