Cryogenics (low temperature physics) has become a critical component of every day life through its use in satellite communications, medical diagnosis, natural gas transport, infrared surveillance, and many more applications. In this new edition of one of the leading books in the field, the authors explain the underlying principles and effects of cooling systems, liquid nitrogen, liquid helium and the approach to absolute zero. Accompanied by instructive illustrations throughout, the text covers all aspects of cryogenics including, a historical perspective, basic physics, construction...
