Cryogenics - the science that addresses the production, effects and maintenance of very low temperatures - underpins a range of enabling technologies that impact our daily lives in ways that are not immediately apparent. This book provides a practical, hands-on reference source to promote exploitation and innovation in all areas of cryogenic science and technology. The book is particularly designed to aid those practitioners coming newly into Cryogenics, giving them a context and signposts for where to go for further information. It spans a broad range of applications and undoubtedly will contain new information useful to those already involved with Cryogenics.
