This title's readership includes engineers, scientists and students working in all areas of cryogenics and superconductivity as well as those working in areas that use cryogenics as an enabling technology (e.g. High Energy Physics, Astronomy, Space exploration, Materials science and Fusion energy). As this is an archival volume of cryogenic research, it should be included in the collections of all major University and research libraries as well as libraries maintained by National Labs and research centers. The information in these proceedings will be of interest to both US and foreign researchers and engineers. This conference is the principal North American Conference on cryogenic engineering. It is attended by scientists and engineers from all over the world. The papers published here have been fully refereed and cover all aspects of cryogenic engineering including: refrigeration, superconductivity, cryocoolers, air liquefaction, heat and mass transfer, insulation systems, cryostat design and space cryogenics.
