Book Description
Twenty five years have elapsed since the original publication of Helium Cryogenics. During this time, a considerable amount of research and development involving helium fluids has been carried out culminating in several large-scale projects. Furthermore, the field has matured through these efforts so that there is now a broad engineering base to assist the development of future projects. Helium Cryogenics, 2nd edition brings these advances in helium cryogenics together in an updated form. As in the original edition, the author's approach is to survey the field of cryogenics with emphasis on helium fluids. This approach is more specialized and fundamental than that contained in other cryogenics books, which treat the associated range of cryogenic fluids. As a result, the level of treatment is more advanced and assumes a certain knowledge of fundamental engineering and physics principles, including some quantum mechanics. The goal throughout the work is to bridge the gap between the physics and engineering aspects of helium fluids to provide a source for engineers and scientists to enhance their usefulness in low-temperature systems. Dr. Van Sciver is a Distinguished Research Professor and John H. Gorrie Professor of Mechanical Engineering at Florida State University. He is also a Program Director at the National High Magnetic Field Laboratory (NHMFL). Dr. Van Sciver joined the FAMU-FSU College of Engineering and the NHMFL in 1991, initiating and teaching a graduate program in magnet and materials engineering and in cryogenic thermal sciences and heat transfer. He also led the NHMFL development efforts of the cryogenic systems for the NHMFL Hybrid and 900 MHz NMR superconducting magnets. Between 1997 and 2003, he served as Director of Magnet Science and Technology at the NHMFL. Dr. Van Sciver is a Fellow of the ASME and the Cryogenic Society of America and American Editor for the journal Cryogenics. He is the 2010 recipient of the Kurt Mendelssohn Award. Prior to joining Florida State University, Dr. Van Sciver was Research Scientist and then Professor of Nuclear Engineering, Engineering Physics and Mechanical Engineering at the University of Wisconsin-Madison from 1976 to 1991. During that time he also served as the Associate Director of the Applied Superconductivity Center. Dr. Van Sciver received his PhD in Low Temperature Physics from the University of Washington-Seattle in 1976. He received his BS degree in Engineering Physics from Lehigh University in 1970. Dr. Van Sciver is author of over 200 publications and patents in low temperature physics, liquid helium technology, cryogenic engineering and magnet technology. The first edition of Helium Cryogenics was published by Plenum Press (1986). The present work is an update and expansion of that original project.

Book Description
Cryogenics, a term commonly used to refer to very low temperatures, had its beginning in the latter half of the 19th century. Traditionally, this field is separated from Cryogenic Engineering and Low Temperature Physics (LTP). Cryogenic engineering is concerned with the design and development of low-temperature systems and components, while low temperature physics is more related to the fundamental research of material or fluid properties. This book discusses some recent findings and developments as well as gives an outlook on the fields of helium cryogenics and LTP. The main focus will be given to the helium cryogenics, though a smaller review is also presented for the fields of cryogenic energy storage facilities. Some future trends and R&D activities are also discussed. To orient the reader, the first four chapters are related to LTP, while the major part of the book is then devoted to helium cryogenics, for example, refrigeration techniques, cryostats, low temperature electronics, safety, etc.It should be particularly suited for advanced students, young researchers or engineers, who are intending to proceed with careers in helium cryogenics or LTP. However, the authors believe that the book will also be of value to experienced scientists, since it describes several very recent advances in experimental low temperature physics and technology, for example, ultra-low temperature technique and thermometry, as well as progress in helium cryogenics, such as heat transfer, cryostat designs for large facilities, and refrigerator developments. Extensive references are provided for the readers interested in the details of the cryogenic engineering advances. And last but not least, the authors hope that this book will widen the horizons of many without a solid state background, but with a general interest in low temperature physics and helium cryogenics.In attempting to cover such a wide field, a large degree of selection has been necessary, as complete volumes have been written on many topics which here have had to be covered in very few pages or less. It is inevitable that not everyone will agree with the present choice, especially if it is their own subject which has been discussed very briefly or not mentioned at all, and the editor accepts full responsibility for the selections made. The book is written at a level which should be followed by a university graduate in science or engineering, although, if their background has not included a course in cryogenic engineering, general or solid-state physics, some groundwork may be lacking.

Book Description
The aim of this book is to provide information about performing experi ments at low temperatures, as well as basic facts concerning the low tem perature properties of liquid and solid matter. To orient the reader, I begin with chapters on these low temperature properties. The major part of the book is then devoted to refrigeration techniques and to the physics on which they are based. Of equal importance, of course, are the definition and measurement of temperature; hence low temperature thermometry is extensively discussed in subsequent chapters. Finally, I describe a variety of design and construction techniques which have turned out to be useful over the years. The content of the book is based on the three-hour-per-week lecture course which I have given several times at the University of Bayreuth between 1983 and 1991. It should be particularly suited for advanced stu dents whose intended masters (diploma) or Ph.D. subject is experimental condensed matter physics at low temperatures. However, I believe that the book will also be of value to experienced scientists, since it describes sev eral very recent advances in experimental low temperature physics and technology, for example, new developments in nuclear refrigeration and thermometry.
