In the early 1980s, Graham Walker wrote his classic two-volume monograph Cryocoolers . Sections of that landmark work have been referenced more often and by more authors than any other cryogenic paper published in the mid-1980s. Nevertheless, in so dynamic a field, an update--one that is compact, inexpensive, and more ranging--is urgently needed. Low-Capacity Cryogenic Refrigeration provides an elementary yet comprehensive introduction to the subject, and features clear discussions of applications to scientific, medical, educational, military, and civil systems. Complementary to the earlier two-volume work, the book covers a wider range of topics and offers a wealth of information about the new developments in the last fifteen years. In addition to descriptions of all the principal methods to achieve low-capacity cryogenic refrigeration, this new volume contains a valuable guide to the literature sources, and references more advanced works. Physicists, chemists, and engineers concerned with low-temperature refrigeration will welcome this new book by an eminent authority in the subject.
