Preface Ë xiiiLi-Ming Pan and his group, the Yuxin Machinery Co., Ltd., for providing help for the
rectangle-shape thin-bottom liquid nitrogen vessel. This book is based on the research
work of the ASCLab group that is composed of the above-mentioned researchers and
ACSLab alumni including Dr. Min-Xian Liu, Hua Jing, Qing-Yong He, Yu-Jie Qing, Dong-
Hui Jiang, Chang-Qing Ye, and Xing-Zhi Wang, whose work we are also thankful
for. We also thank my colleagues and friends outside our team for discussions and
exchanges about the HTS Maglev during their visits to our laboratory: Prof. Y. Iwasa
of the Francis Bitter Magnet Laboratory of MIT in USA, Dr. Frank N. Werfel of the
Adelwitz Technologiezentrum GmbH (ATZ), Dr. E. H. Brandt of the Institut für Physik,
and Dr. Wolfgang Gawalek of the IPHT-Jena in Germany, Prof. M. Izumi of the Tokyo
University of Marine Science and Technology, Prof. Masato Murakami of the Shibaura
Institute of Technology, Dr. Hiroyuki Fujimoto of the Railway Technical Research
Institute in Japan, Prof. Richard M. Stephan of the Federal University of Rio de Janeiro
in Brazil, and Prof. Du-Xing Chen of the Universitat Autonoma Barcelona in Spain.
During his visit, Prof. Iwasa presented draft chapters of his bookCase Studies in
Superconducting Magnets, Second Editionin three lectures. Not long after his visit
to ASCLab, Dr. Brandt got terminally ill. He gave his entire research archive to us
before he passed away. We will always remember the important contribution he made
to superconductor research and his devotion to scientific research. The continuous
collaboration between Werfel’s group and our team has been highly productive. As
part of the project of science and technology cooperation between the government
of China and Germany in 2004–2005, extensive and in-depth exchanges between our
team and Dr. Ludwig Schultz’s group of the IFW was conducted, and this cooperation
promoted the HTS Maglev development. Prof. Archie Campbell of Cambridge Univer-
sity in the UK sent the details of his research findings on Maglev in 2001. We also
acknowledge the National High-tech R&D Program (National 863 Program) and the
National Natural Science Foundation in China for their long-term research grants for
the HTS Maglev project from 1990 to 2010. Last but not least, we thank Wei Wang at
Cambridge University and Xin-Ju Wang at Intel for proofreading Chapters 1 to 6. We
highly appreciate Prof. D. G. Naugle at Texas A&M University for reviewing this book
rigorously.
